Thermal Comfort in Marine Workshop: Environmental Ergonomics Measurement Approach

Abstract

A field study conducted was to identify and determine the environmental ergonomics factor level in Marine 2-stroke Engines Workshop and Multifuel engines workshop. Thermal comfort is considered the main factor which is often emphasized by the occupant of the accommodation unit. The ambient temperature and relative humidity will lead to thermal comfort. Thermal comfort were calculated using the PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) according to the ISO 7730. Measurement data for all factors were collected by mean of “Thermal Comfort Multistation” before the data is then been transferred to Microsoft Excel for further analyze. Through this study, there are six environmental factors quantified by utilizing Thermal Comfort Multi-station (TCM) contrivance. The results were compared with standard the National Institute of Occupational Safety and Health (NIOSH) Malaysia, ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) and ISO (International Standard Organization). The results show that the PMV at the Marine 2-stroke Engine’s Workshop are in the range of 1.50–3. Its mean that the workshop can be conclude as not comfort and the thermal sensation is warm.
