An Offshore Platform rig is a large structure with facilities to drill wells, to extract and process oil and natural gas, or to temporarily store product until it can be brought to shore for refining and marketing. In many cases, the platform contains facilities to house the workforce as well.
An Offshore drilling unit operate by professionals Crew and management system are often the real determining factor concerning MODU performance and safety. This is often overlooked during the flurry of cost analysis, equipment evaluation, operating expenses assessment, and number crunching during bid analysis and MODU selection. It is often said that the low bid does not always give the best performance. A complete “hard” (equipment) and “soft” (crew, management, and safety) analysis must be done to make the best decision.
These policies and procedures should be reinforced throughout the personnel hierarchy, from the chief executive officer to the roustabout on the rig, in order to have a successful and well-performing organization and rig operation.
The staffing and organization of a MODU vary with each drilling contractor, operator, and country, and are controlled by classification and registration requirements. The most senior person on the MODU is usually the offshore installation manager (OIM) who is, by law, the “master” or “captain” of the vessel. The OIM is responsible for all departments, including:
- Drilling
- Maintenance
- Marine
- Auxiliary services
- Safety
The following are personal who working in the offshore platform:
1. OIM (offshore installation manager);
2. Operations team leader (OTL);
3. Offshore operations engineer (OOE) who is the senior technical authority on the platform;
4. PSTL or operations coordinator for managing crew changes;
5. Dynamic positioning operator, navigation, ship or vessel maneuvering (MODU), station keeping, fire and gas systems operations in the event of incident;
6. Automation systems specialist, to configure, maintain and troubleshoot the process control systems (PCS), process safety systems, emergency support systems and vessel management systems;
7. Second mate to meet manning requirements of flag state, operates fast rescue craft, cargo operations, 8. Fire team leader;
9. Third mate to meet manning requirements of flag state, operate fast rescue craft, cargo operations, fire team leader;
10. Ballast control operator to operate fire and gas systems;
11. Crane operators to operate the cranes for lifting cargo around the platform and between boats;
12. Scaffolders to rig up scaffolding for when it is required for workers to work at height;
13. Coxswains to maintain the lifeboats and manning them if necessary;
14. Control room operators, especially FPSO or production platforms;
15. Catering crew, including people tasked with performing essential functions such as cooking, laundry and cleaning the accommodation;
16. Production techs to run the production plant;
17. Helicopter pilot(s) living on some platforms that have a helicopter based offshore and transporting workers to other platforms or to shore on crew changes;
18. Maintenance technicians (instrument, electrical or mechanical).
19. Fully qualified medic.
20. Radio operator to operate all radio communications.
