OIM (offshore installation manager)


OIM (offshore installation manager)

The OIM is the most senior member of management on many larger drilling rigs, particularly large jack-up rigs and some semi-submersibles. On smaller rigs the Tool Pusher will usually be the most senior member of management, but will work under the OIM when one is present. Next in line of command would be the Driller (oil), who is in charge of the Roughnecks and Roustabouts.

In the UK oil and gas sector all offshore "installations" i.e. Production platforms and FPSO's (Floating Production Storage and Offloading Vessels) it is mandatory in law to have an "OIM" on board at all times.

The "OIM" is responsible for all matters of Health and Safety on board the installation and assumes the role of "On Scene Commander" in the event of an emergency. This means that he/she is responsible for managing the response to any emergency. In addition to this key emergency responsibility the OIM also manages all day to day aspects of the Oil and Gas production operation generally including; Budgets, Personnel, Production, Maintenance, Logistics (helicopters/supply boats/dive vessels etc).

On production installations the deputy OIM would generally be the Offshore Team Leader/Operations Engineer/Operations Superintendent, although on FPSO's this deputy position may be held by the Marine Superintendent - who must hold a master mariner qualification.
