Gulftide Conversion

Successful projects don't just happen. A successful MOPS conversion requires the right blend of people, systems and experience. All three were combined in the schedule-driven conversion of the jackup Gulftide using Oceaneering's fast-track project management methods. Highlights of the project include:

• Conversion accomplished in 115 days
• Simultaneous engineering & construction
• 240,000 manhours of work performed

UMC Petroleum Corp. contracted Oceaneering in February 1995 to convert and install the jackup drilling rig Gulftide for MOPS service offshore West Africa. Oceaneering purchased the Gulftide and towed it to a shipyard along the U.S. Gulf Coast, where work began immediately to remove drilling equipment and refurbish the venerable jackup. All conversion work was completed by June 26. The jackup MOPS was then loaded aboard a heavy lift transport vessel and dry-towed to West Africa. Upon arrival, Oceaneering supervised installation of the unit adjacent to a wellhead caisson platform and assisted with hookup and production startup, which occurred as scheduled on October 1, 1995.

Under the contract, Oceaneering provided engineering and project management for the rig conversion, including development of specifications and drawings and supervision of work performed by subcontractors. We contracted with the shipyard for all fabrication and installation services and provided procurement services to purchase all equipment and materials for the conversion process. Additionally, Oceaneering was responsible for classing the jackup MOPS with the American Bureau of Shipping and for assisting with preparation of the unit for the tow to West Africa.

Oceaneering supervised installation of the Gulftide at the field site and provided technical assistance for hookup and production startup. Following production startup, Oceaneering continued to provide technical support to the project, including coordination with all classification, registration, and certification authorities for the MOPS. Field support efforts included the upgrades of two gas generation sets and development of catastrophic protection and preventive maintenance plans for the MOPS.
