1 Introduction

High-hazard industries, such as aviation and healthcare, rely heavily on effective functioning of teams primarily due to the complex, dynamic, and safety critical nature of their industries. It is not enough that these teams are made up of individual experts, but the team itself must be an expert team (Salas et al. 1997) in order to demonstrate high levels of not only technical performance but also team attitudes and behaviours to operate safely and adaptively to achieve their goals. An expert team is characterised, according to Salas et al. (2006), as having “a set of interdependent team members, each of whom possesses unique and expert-level knowledge, skills, and experience related to task performance, and who adapt, coordinate, and cooperate as a team, thereby producing sustainable, and repeatable team functioning at superior or at least near-optimal levels of performance” (p. 440).

Teams working on drilling rigs share similar characteristics to those in aviation and healthcare in that they operate in high-hazard environments where situations are dynamic, risky, uncertain, involve multiple operators, and where membership is not stable. Drilling teams are made up of skilled individuals who may or may not know each other and may not have worked together previously, moreover, team members can be geographically remote (Lauche et al. 2009). Key members of a drilling team, as illustrated in Fig. 1, include representatives from the operator, the contractor, and service companies (i.e. specialists who work within the team for varying periods of time dependent on the phase of operations). As Haavik (2011) states, cooperation between different disciplines and division of labour can lead to issues with differing goals, perspectives, and timescales.

Drilling team key roles and interactions

These personnel may only meet once the drilling plan is ready to be operationalised and will have to rapidly form an effective team. This team will work together for the duration of the drilling programme which may last weeks or months. The emphasis traditionally for drilling teams has focused on technical competence of team members, with less recognition of the impact of non-technical skills. However, following analyses of accidents in the oil and gas industry, including the Macondo tragedy in April 2010 (Chief Counsel 2011), there is growing recognition of the influence of skills such as communication, situation awareness and decision-making on safety.

Dynamic situations require that teams, particularly “control crews”, are trained to react in an effective and timely manner. Control crews are defined by Waller et al. (2004) as highly trained teams responsible for monitoring complex systems, performing routine procedures, and quickly responding to non-routine situations. Team members need assurance that their colleagues know and understand their roles and responsibilities, and can use their skills and knowledge individually and collaboratively to intervene and recover control. Assurance can be developed over time as team members increase their familiarity with each other and improve personal working relationships. Where there is the potential for things to rapidly deteriorate from ‘normal’ conditions to ‘abnormal’ conditions, such as in aviation when severe weather occurs, in healthcare when a patient responds unpredictably during an operation, or on the drill floor when a routine task starts to go wrong due to equipment failures, there is even more reliance on the team to respond quickly and adaptively to manage the situation (Entin and Serfaty 1999).

High reliability industries have typically introduced training, such as crew resource management (CRM: Helmreich and Foushee 1993; Helmreich et al. 1999), to support and enhance team performance. This type of training frequently incorporates simulator-based exercises to allow team members to practise both their technical and non-technical skills and receive feedback on their performance. Non-technical skills, in the aviation environment, refer to “all pilots’ attitudes and behaviours in the cockpit not directly related to aircraft control, system management and standard operating procedures” (van Avermaete 1998, p. 4).

The experiences of aviation and healthcare in integrating simulator-based exercises into training designed to improve safety and performance can therefore provide guidance when developing simulator-based exercises on drill floor simulators. Technical advances in drilling simulator software and hardware now means that simulator-based exercises are increasingly available to develop both the technical and non-technical skills of drilling team members. To ensure that training interventions are suitable for team members to develop and enhance the necessary skills and knowledge to carry out their operations, detailed, standardised guidance is required.

1.1 Five principles for developing simulator-based exercises

Based on the experiences described above, predominantly gleaned from aviation and healthcare, the following five principles should be applied when designing training interventions to improve safety and effectiveness:

Principle 1

Develop learning objectives and expected performance standards.

A team task analysis should precede any training intervention to identify the task and team requirements. Simulator-based training interventions should be developed around specific learning objectives, with predetermined measurements for performance standards. Cues to stimulate the expected behaviours should be embedded into the scenarios to allow the expected behaviours to be practised and demonstrated.

Principle 2

Train the team as a whole (simulator-based team training).

Although much can be gained from training individuals’ non-technical skills, there are huge advantages to training the team as a whole during simulator-based exercises. To improve team effectiveness, teams should be trained as a whole to develop team knowledge, skills, and attitudes, improve coordination, foster shared mental models and accurate expectations of the requirements of the team, and encourage adaptability and flexibility.

Principle 3

Use a structured observation tool (behavioural marker framework).

A structured observation tool should be used in order to capture positive team behaviours as well as areas for improvement. A predetermined descriptive framework should define the behaviours of the key non-technical skills to be observed. The framework can be used as a basis of the training design, used to provide feedback, and used for self-reflection.

Principle 4

Provide feedback during a structured debrief.

Feedback should take place face-to-face immediately following a scenario-based simulator exercise, and highlight team behaviours observed during the exercise. The debrief should focus on the team processes, such as who said what, who was involved in making decisions, which roles were involved in coordinating activities, and so forth, rather than only focus on the outcome of the exercise.

Principle 5

Repeat the simulator-based training regularly to enhance expertise and retain performance standards.

Simulator-based exercises should not be expected to change team behaviours after one exposure. Exercises should be repeated on a regular basis, dependent on access to the simulator, demands on the team, and also how long the team has worked together. Newly formed teams will benefit greatly from sharing experiences on a simulator to develop Team KSAs. Longer-established teams can also take advantage of the opportunity to test out new responses, practise new procedures, or become familiar with new equipment or processes.

This paper explains the rationale supporting these proposed principles. The paper starts by outlining work undertaken by Salas and colleagues emphasising the importance of structured training for improving team performance. The key concepts of simulator-based training (SBT) and simulator-based team training (SBTT) are presented along with a description of SBT in high-hazard environments such as aviation and healthcare, and reported benefits in terms of team behaviours, attitudes, and cognition. The development and use of a behavioural framework to evaluate team performance and provide feedback based on observations of team performance during simulator-based exercises is then outlined. Finally, support for repeated exposure to SBT is provided.

2 Training interventions and team performance

Over the past 25 years, Salas and colleagues have undertaken extensive research into team training and the critical factors involved in the creation of high performing teams, examples of which are summarised in Table 1.

Table 1 Summary of key research by Salas and colleagues into team training requirements and interventions

Salas et al. (1997) commented that training is not always effective in imparting crucial knowledge and skills, highlighting the lack of integration between training theory and training practice. What is required, therefore, are training strategies or guidelines for turning a team of experts into an expert team that includes aspects such as fostering shared mental models of the task and of other team member roles, training team members on teamwork skills (e.g. situation awareness, communication), and developing simulations that allow team members to experience different courses of action Salas et al. (1997). Team training, according to Salas and Cannon-Bowers (1997), comprises a set of tools and methods that, in combination with required [team-based] competencies and training objectives, forms an instructional strategy. The aim of team training is to improve team effectiveness by addressing both individual competencies and developing team competencies.

Team effectiveness depends on individuals attaining a set of competencies including knowledge, skills, and attitudesFootnote 1 (KSAs) (Salas et al. 2002, cited in Flin et al. 2008). Similarly, team competencies are the knowledge, skills and attitudes required by the team as an entity, i.e. Team KSAs, and are dependent on the type of team and the team’s task, that is whether the team is stable with few change-outs of personnel or not, and whether the team’s task is context-specific or variable (Paris et al. 2000). Training interventions therefore must match the requirements of the team, which are typically identified following a team’s competency (Cannon-Bowers et al. 1995) or task analysis (see Stanton et al. 2013 for further information on team task analysis techniques). A rigorous analysis of a team’s competencies and tasks ascertains the required Team KSAs which guide the instructional strategies and learning objectives of a training intervention designed to improve team effectiveness.

Delivery methods for team training, as described by Salas and Cannon-Bowers (1997) can be information-based (providing knowledge, facts, theories or concepts via lectures, presentations, etc.), demonstration-based (observation of videos or other operators), or practice-based (physical participation and feedback). Practice-based methods form the basis of SBT. However, simulator-based exercises in themselves are not enough to train the expected behaviours (see Salas et al. 1998; Assumption 2). What are also required are training strategies, learning objectives, and feedback from trained and competent observers (Salas et al. 2004). In particular, scenarios to be used for SBTT must incorporate events and/or cues to stimulate the practise and demonstration of the identified KSAs. Training structured around learning objectives, exercise design, performance measurement, and feedback has been shown to lead to improved team performance (Dwyer et al. 1999; Rosen et al. 2008; Salas et al. 2007, 2008). This underpins Principle 1 relating to the design of learning objectives and expected performance standards.

3 Simulator-based training (SBT)

Simulator-based training is defined as an instructional technique that accelerates expertise and skills development by providing active learner engagement, repetitive practice, variable scenario complexity, and performance measurement and feedback (Owen et al. 2006). SBT is characterised by “feedback, repetition, variations in degree of difficulty, use in a controlled environment and defined outcomes for measureable learning” (Issenberg et al. 2005, as cited in Bilotta et al. 2013, p. 4). As an experiential based learning technique, SBT involves active engagement and cognitive experiences based on realistic events (Fanning and Gaba 2007). Participants can apply their learning and experiences in a simulated environment, test out new responses and actions, and can respond adaptively to situational changes.

Simulators can range from low fidelity, such as paper and pen or computer games (Baker et al. 1993) through to high fidelity, virtual reality cockpit simulators (RAEs 2009), dependent on aspects such as cost-effectiveness, space, location, demand, and so forth. However, it is not the case that the higher the fidelity, the higher the opportunity for enhanced learning, rather it is the design of the training programme, based on training strategies as discussed above, that is crucial (Beaubien and Baker 2004). An effective SBT relies upon equipment fidelity, environment fidelity and psychological fidelity, with the latter being the most important for teamwork skills training. That is, that the simulation itself needs to closely match how tasks are performed in the real world; the simulation has to replicate the cognitive processes that would be experienced in the actual environment (Kozlowski and DeShon 2004). The potential of transfer of training from simulator-based exercises to reality is therefore increased.

SBT, in terms of both low to high-fidelity simulators, have been introduced in aviation and healthcare to enhance the skills, both technical and non-technical, of operators. The next section describes the experiences of both these sectors in terms of the benefits gained from the introduction of SBT in terms of improved safety and effectiveness.

3.1 Aviation

Crew resource management is a training intervention designed to support the development of interpersonal aspects of flight operations (Helmreich et al. 1999; Helmreich 2002). At the core of a CRM training programme are CRM skills, also known as non-technical skills. These skills are the cognitive, social and personal resource skills that complement technical skills, and contribute to safe and efficient task performance (Flin et al. 2008). CRM was introduced following the recognition that the majority of aviation accidents were attributable to human error, such as failures in coordination (Salas et al. 2004). Teamwork competencies are essential for aviation teams, particularly as these tend to be ad hoc teams in that the team members vary almost on a flight-by-flight basis.

In order to reduce the frequency of human errors, and to enhance non-technical skills, the aviation industry has typically integrated SBT into CRM training courses. SBT for aviation can range from low-fidelity simulation, such as role play or tabletop computer-based simulators (Baker et al. 1993), through to full-flight simulators (RAeS FSG 2009). Dependent on the task requirements, different levels of simulator fidelity can be used for specific objectives. For example, operations such as practising complex avionics or engine start procedures can be carried out on a low-fidelity simulator, whereas using a full-flight simulator allows aircrew to practise managing severe weather conditions, or even dealing with an engine failure, but in a safe environment. The intensity of SBT assists crew to handle challenging, but infrequent, situations (Bilotta et al. 2013).

The use of SBT is considered to have improved training standards and also contributed to improved aviation safety, according to Wise et al. (2010), through the introduction of CRM. As Bilotta et al. (2013) comment, SBT is now accepted by pilots (and mandated by aviation authorities) as a reliable and trustworthy educational tool (Cook et al. 1998).

Due, in part, to the benefits of SBT and non-technical skills training in improving safety, lessons learned from aviation have been used by other high-hazard industries. Healthcare, in particular, has adopted SBT for a range of settings including emergency medicine (Weaver et al. 2010), resuscitation (Ornato and Peberdy 2014), anaesthesia (Gaba 2010), obstetric crisis team training (Robertson et al. 2009) and interprofessional medical teams (Fung et al. 2015), as discussed below.

3.2 Healthcare

Toff (2010) comments that healthcare can learn much from the evolution of aviation safety, especially anaesthesia. He further suggests that the relevance of human factors in improving safety acknowledged in aviation was instrumental in the introduction of CRM-type training interventions being introduced in anaesthesia (Gaba et al. 2001). CRM training has also been introduced for surgeons leading to improvements in team coordination and reductions in errors (Guerlain et al. 2008). Comparing aviation and healthcare in terms of the use of simulation, Sir Liam Donaldson, Chief Medical Officer of England, cited in his 2009 annual report, ‘That when a person steps on a plane, their risk of dying in an air crash is 1 in 10 million. When a person is admitted into hospital, their risk of dying or being seriously harmed by a medical error is 1 in 300” (DOH 2009, p. 51). Sir Liam comments, amongst a number of key points, that surgeons trained on simulators make fewer errors and carry out technically more exact procedures (2009). Furthermore, simulators as highly realistic training environments are valuable for training and developing clinical teams, especially for providing behavioural debriefing. The report’s recommendations include that “The importance of human factors training to safe care should be widely communicated”.

Notwithstanding the Chief Medical Officer’s statement that simulation in the healthcare system still requires further expansion, the use of simulation has grown in the UK over the past 20 years. A number of general findings have been identified across the range of medical settings where SBT has been introduced relating to the structure and method of training, the importance of feedback and debriefing, facilitation, and the overall benefits of SBT.

It is worth noting that, similar to aviation, SBT in healthcare can be implemented on simulators with low physical fidelity (Weaver et al. 2010), or even on portable simulators (Paige et al. 2008), i.e. a transportable simulator that can be taken to different locations for training purposes. Low-fidelity simulations are often as useful as higher-fidelity simulations, as long as the psychological/cognitive fidelity of the tasks undertaken on the simulator is high (Bowers et al. 1992). Kneebone (2010) comments that, in healthcare, the relationship between clinical and simulator-based practice is a mutually dependent, two-way process, and that the simulation should mirror the essentials of a clinical setting but only needs to be ‘good enough’ to engage participants and achieve learning goals. Paige et al. (2008) found significant improvements in team competencies, such as role clarity, anticipatory response, cross-monitoring, and team cohesion and interaction, based on the use of a portable simulator.

3.3 Maritime and offshore oil and gas

In the maritime setting, specially designed simulators that realistically simulate complex conditions on board vessels have been used to provide experience and improve both technical and non-technical skills (Baldauf et al. 2012). Full-mission simulators are integral to the training of non-technical skills through CRM-type training courses specifically focused on learning attitudes, behaviours and cognition on board ship as practised in simulator-based exercises (Barnett et al. 2006; Hanzu-Pazara et al. 2008). Related to maritime transportation, SBT courses for offshore anchor handling vessels targeting teambuilding, leadership, and communication have shown positive influences for both individuals and groups (Havold et al. 2015).

Currently, in the oil and gas industry, simulators are predominantly used for technical training (Frink et al. 2004—coiled tubing; Veitch et al. 2008a—evacuation training; Veitch et al. 2008b—emergency response training) with little explicit emphasis on non-technical skills. Desktop simulators are used during assessment exercises for technical expertise by individuals for well-controlled accreditation training (IOGP 476). A high-fidelity power distribution simulator has also been designed and is currently being used for Responsible Electrical Person (REP) training (Moffat and Crichton 2015) for drilling rig electricians as well as electricians on production vessels. In this latter case, the focus is on both technical and non-technical skills of individuals resolving complex scenarios.

Non-technical skills training is increasingly being considered by the offshore oil and gas industry to enhance safety and performance (Energy Institute 2014). Guidance on the implementation of Well Operations Crew Resource Management has been published by the International Association of Oil and Gas Producers (IOGP) (WOCRM: IOGP 502) with the aim of providing learning objectives for CRM competencies/non-technical skills as well as guidance on training delivery and assessment. SBT is considered to be preferable, but not essential, for WOCRM training (IOGP 501).

3.4 Drilling

Given the predominance and experiences of simulation and SBT in aviation and healthcare, and the reported benefits in terms of the development of competence in both technical and non-technical skills, the drilling sector can learn much from these industries. The technical advances in building high-fidelity drill floor simulators provides the opportunity for drill teams to practise operations, especially high risk operations such as managing well control incidents, and to enhance the effectiveness of the team to become more flexible and adaptable in terms of their social and cognitive skills.

Drilling simulators can range from desktop well control simulators used by individuals during certification training to high-fidelity full-scale drill floor simulators designed for team training. High-fidelity drilling simulators mimic the layout of a drill floor, typically involving two cyber chairs for the roles of the driller and the assistant driller. The cyber chairs support electronic instrumentation for drilling processes such as setting pumps and rotary speeds, with data being displayed on human–machine interfaces (HMIs) attached to the chairs. Illustrations of virtual reality graphics of rig floor operations can also be presented to the team members. Additional drilling team roles can access the drilling data using separate HMIs displayed throughout the simulator suite. As drilling operation exercises are underway, team members communicate verbally while assessing situations and making decisions. Facilitators can introduce unexpected events or complexities into the scenario during the exercise to test out the individual’s and team’s knowledge and expertise.

Due to the relative stability of the team and the duration of time involved in drilling a well, or series of wells, there is a greater emphasis in drilling teams for teams to receive training and practise as a complete entity. This then leads to a greater requirement for SBTT.

4 Simulator-based team training (SBTT)

Simulator-based team training expands on the concepts of SBT to develop, practise, and enhance team competencies and KSAs. Whereas SBT provides active learner engagement, repetitive practice, and the ability to vary complexity in scenario-based exercises, along with directed feedback (Weaver et al. 2010), SBTT advances teamwork skills, such as team communication, cooperation and coordination, situation awareness, and shared mental models. Hamman (2004) comments that training programmes often focus on individual responsibilities but healthcare requires interdisciplinary teams, and therefore simulator-based interdisciplinary team training which crosses organisational divisions is required to allow communication, accountability, and teamwork, to be effective. SBTT has been used with a multidisciplinary healthcare team comprising surgeons, anaesthetists and nurses (Bilotta et al. 2013) where team members come together to work as a team. Teamwork training undertaken in an immersive simulator environment can expand traditional training leading to improved performance and reduced errors (Lateef 2009).

Reviewing the before, during and after effects of SBTT, Weaver et al. (2010) conclude that when bringing together a group of experts (e.g. clinicians), it is essential that the group knows how to coordinate, shares expertise, and is motivated to work as a team, in order to work safely and effectively. These authors have proposed recommendations to grow SBTT as a viable and efficient method to develop teamwork expertise in the US healthcare system. In this sense, SBTT requires training strategies, content, and methods, utilises either high- or low-fidelity simulation, and includes diagnostic feedback. Reductions in errors and performance improvements, as well as a significantly positive impact on teamwork behaviour in a medical setting, have been reported following SBTT compared to a control group (Morey et al. 2002; Shapiro et al. 2004). Similarly, Robertson et al. (2009) found positive changes in attitudes, perception of individual and team performance, and overall team performance following the introduction of an SBTT programme.

In sum, SBTT has been introduced in a variety of settings where teams must function safety and effectively. Such teams may comprise a number of team members, involve a variety of specialisms, and work in stressful situations, such as aviation and healthcare. Principle 2 is train the team as a whole (simulator-based team training).

5 Evaluating team performance: behavioural marker framework

The use of SBT and SBTT then raises the issue of the evaluation of performance and potential benefits directly linked to safe outcomes. A variety of methods have been developed to be used by observers to assess different aspects of team performance in complex systems (Stanton et al. 2013). These typically focus on technical skills and include Behavioural Observation Scales (BOS: Latham and Wexley 1977) and Behaviorally Anchored Rating Scales (BARS: Bernardin and Smith 1981). In order to address non-technical skills performance, however, behavioural marker frameworks are typically utilised (Flin and Martin 2001). Behavioural markers are defined as observable, non-technical behaviours that contribute to superior or substandard performance within a work environment (Klampfer et al. 2001; Carthey et al. 2003). The UK Civil Aviation Authority propose that it is necessary to assess the CRM [non-technical] skills of flight crew members from time to time (CAA 2006) and behavioural marker frameworks provide the basis for such an assessment. The purpose of an assessment is to give feedback to trainees, test skills in a competence assurance system, ascertain whether a CRM training programme has been effective, and audit the level of skill demonstrated in a work unit (Flin et al. 2008).

Associated initially with aviation CRM training programmes, descriptive behavioural marker frameworks have been developed as a means of defining and evaluating the behaviours relating to the key non-technical skills required by crew members. Examples from aviation and healthcare include Non-technical Skills (NOTECHS: van Avermaete and Kruijsen 1998), Anaesthetists Non-technical Skills (ANTS: Fletcher et al. 2003, 2004), and Non-technical Skills for Surgeons (NOTSS: Yule et al. 2008). It is acknowledged, however, that behavioural markers need to be validated and that raters using the systems must be adequately trained (Jepson et al. 2015).

Specific to team performance, an observational system, Observational Teamwork Assessment for Surgery (OTAS: Undre et al. 2006), has also been designed to provide a measure of teamwork on outcomes in the operating theatre. The OTAS system comprises a procedural task checklist for the patient, equipment and communication tasks, as well as ratings on team behaviour constructs such as communication, cooperation, coordination, shared-leadership and monitoring. Similarly, the University of Texas Behavioral Markers for Neonatal Resuscitation (UTBMNR: Thomas et al. 2004) is an audit form which aims to improve teamwork in healthcare to reduce and manage errors. A Team Behavioural Marker framework has also been developed and tested on drilling team behaviours during SBTT sessions (Crichton and Moffat 2015), with the four categories being Team Decision Making, Team Situation Awareness, Teamwork and Communication, and Team Workload and Stress Management.

Behavioural marker systems are often used both in real-life situations and during SBT sessions. The ultimate aim of the systems is to capture team performance behaviours, which will then be used as a basis for feedback during a debrief to improve performance. Principle 3 is to use a structured observation tool (behavioural marker framework) during simulator-based exercises.

6 Debrief and feedback

One aspect of SBT and SBTT almost universally deemed to be essential to improving performance is that of debriefing and feedback (Fanning and Gaba 2007). Debriefing is the critical phase of learning, as new information is given meaning (Barnett et al. 2006). Typically undertaken following a simulator-based exercise, a debrief offers constructive feedback to enhance learning and skill retention (Barnett et al. 2006; Bilotta et al. 2013; Havold et al. 2015). Ideally, a structured debrief should take place immediately following the termination of the training session (Weaver et al. 2010), and should reinforce lessons learned during the training as well as revisit the learning objectives (Beaubien and Baker 2004). The value of debriefing is highlighted by a finding that a 20–25% improvement in individual and team performance occurred following the introduction of debriefing (Tannenbaum and Cerasoli 2013). These authors propose four essential elements for a debrief including: active (vs. passive) self-learning, developmental (vs. administrative) intent, specific (vs. general) events, and multiple (vs. single) information sources.

Issenberg et al. (2005) propose that feedback is the most important feature of SBT medical education. In a review of SBTT in healthcare, Weaver et al. (2010) comment that trainees reflected on their performance in terms of both the outcome of the session and the process. The combination of both outcome and process feedback from sources such as self, peers, and facilitator assists with acquiring a more valid picture of performance. Reflecting on performance (either self-reflection by the trainee or facilitator-guided) should include what went well, what went wrong, why it went that way, and what can be learned from the experience.

In healthcare, debriefs are considered to be critical for improving patient safety as a part of training teams to successfully manage emergencies (Fanning and Gaba 2007). A debrief should be structured to ensure effective reflection and learning, and Lederman (1992) suggests seven elements for a debrief including the person conducting the debrief, the participants to be debriefed (who may indeed be the same in the case of self-reflected debriefing), an experience (such as a simulation exercise), the impact of the experience, recollection, report, and time. A tool for structured debriefings following SBTT, named TeamGAINS (Kolbe et al. 2013), has been designed and incorporates guided team self-correction, advocacy-inquiry, and systemic-constructivist techniques. Tests of this tool during SBT of clinical and behavioural skills for anaesthesia staff indicated a positive effect on psychological safety and leader inclusiveness following the debriefings.

Given the recognition of the importance of debriefs following SBT sessions to improve performance and behaviours, this raises the issue of the skills of an observer to provide effective feedback. Observers must be able to sensitively and constructively address non-technical skills, which can be more challenging than feeding back observations on technical skills. Based on experiences from aviation in providing non-technical skills training and debriefing, Dismukes and Smith (2000) describe the skills required for facilitation and debriefing. In healthcare, specific debriefing techniques for instructors have been identified (Rudolph et al. 2006). Fanning and Gaba (2007) to highlight the role of the facilitator in the debriefing process in that the facilitator should not act as a ‘teacher’ but rather should guide and direct the critical analysis of performance. Principle 4 is to provide feedback during a structured debrief.

7 Frequency of simulation training

In order to increase skills and knowledge, context-specific training opportunities must be experienced. Training is an ongoing process used to counteract the potential for skill degradation if little-used skills are not practised in situ. The development of expertise is the end result of individuals’ prolonged efforts to improve performance (Ericsson et al. 1993). While it is generally accepted that a training experience should not be a one-time activity (Beaubien and Baker 2004), one area of SBT and SBTT which still appears to remain unclear is that of how frequently training, especially using simulators, should occur (Shapiro et al. 2004). Kneebone (2005) suggests that one of the four key areas that underpin SBT is gaining technical proficiency through repeated practice. Such simulator-based repeated practice provides the opportunity to consolidate recently acquired skills within a defined curriculum. However, little research is available demonstrating the optimal frequency of recurrent training to retain performance levels.

Repetitive practice is a key feature in the use of high-fidelity simulations in medical education (Issenberg et al. 2005), but again there is variability in the regularity of programming of simulator-based exercises. High-hazard industries, such as aviation, nuclear power production, oil and gas industry, address competency assurance of safety critical roles, typically involving simulator-based exercises and observations; however, even in these settings there is little consistency in assessment timescales which can range from 6 months to 3 years (Flin 2005). In the UK, the Civil Aviation Authority (CAA) recommend that recurrent training in CRM should take place over a period not exceeding three years (CAA 2006). More research is required into how frequently simulator-based repeated practice should occur to maintain competence, bearing in mind that this will be affected by the type of operations and safety criticality of the individual’s and team’s tasks. Principle 5 is to repeat the SBT regularly to enhance expertise and retain performance standards.

8 Discussion

This paper reviews SBT and SBTT in order to identify the core principles that could be gleaned from other settings where SBT and SBTT has previously been implemented. Once identified, these principles should then be taken into account when developing training interventions for drilling teams. Aviation and healthcare comprise the two main industries where SBT and SBTT have been increasingly integrated into training interventions particularly to reinforce effective individual and team behaviours, and to improve safety. In both cases, simulation, whether low or high fidelity, is the medium that is used due to the opportunity to rehearse, test out, and reinforce decisions and actions.

In healthcare, there is a significant and growing recognition that SBT is educationally effective not only to develop technical skills but also to maximise safety and minimise risk, especially to patients (Ziv et al. 2003). Research by Riley et al. (2011) found an interdisciplinary team training programme in a medical setting using in situ simulation found significant improvements in non-technical skills leading to a 37% improvement in perinatal safety. Similarly, the impact of SBT and SBTT in aviation has been driven by its contribution to safety, as handling the aircraft during different conditions (e.g. severe weather, system failures, and unexpected situations) can be practised in a low risk environment.

A recognised aspect of planning and preparing for well operations in drilling is that of Drill the Well on Paper (DWOP) where relevant team members, representing the operator, the contractor and service companies, come together to review the drilling plan. Steps in the plan are examined, and methods are discussed to improve communication, performance, efficiency, and safety as well as risks and mitigations. A recent development is that of Drill the Well on the Simulator (DWOS) where more challenging sections of the drilling plan can be tested out on a simulator, and modifications can be made prior to operations commencing.

Analyses of accidents and near-misses during drilling operations have highlighted the impact of non-technical skills on safety and performance. In response, the drilling industry is now endorsing non-technical skills training for drilling teams. At this early stage in the development of non-technical skills training in oil and gas and the introduction of interventions incorporating simulator-based scenarios, such as CRM (IOGP 501; IOGP 502), lessons can be learned from the experiences of other high-hazard industries to the benefit of the individual, the team, and the industry, in terms of safety and performance especially for drilling teams. The five principles presented here provide guidance for designing and developing SBT, particularly for drilling teams, such as CRM/non-technical skills training courses, to enhance safe behaviours and performance.
