The Safety of PES in the Offshore Industry

Conference paper


The paper commences by outlining the development of legislation in the UK Continental Shelf, explaining why it has moved from a prescriptive (rule-based) regime to a goal setting approach. The flexibility provided by goal-setting has encouraged innovation and more cost effective solutions.

This approach should be welcomed by PES engineers who are themselves coping with one of the most rapidly advancing technologies. The paper sets out the main thrust of the emerging standards and guidelines: the use of risk-based approaches, and the demonstration that risks have been reduced as low as reasonably practicable (ALARP). This emphasis is in harmony with the new regulatory approach.

The role of independent verification in the forthcoming UK Design and Construction Regulations is then described, and a proposal for satisfying these requirements in the context of the emerging standards is presented.
