The Mineral Workings (Offshore Installations) Act 1971 requires the appointment of an offshore installation manager (OIM) for UKCS installations. The regulations give the OIM general responsibility for safety, health and welfare and for maintaining discipline and order on the installation. At the present level of offshore activity (July, 1991), it is estimated that 400 - 500 OIMs are currently working on UKCS installations. There has been little if any formal research into the selection and training of OIMs or into the day to day demands of this managerial position. This paper presents preliminary data from a survey of the OIMs on the UKCS, which was designed to collect details of experience, training, work schedules, job responsibilities and perceptions of job satisfactions and hassles.
