HOUSTON– InterMoor has successfully completed decommissioning the Innovator platform at Gomez field in the Gulf of Mexico.

The scope of work, conducted in Mississippi Canyon block 711 in 910 m (2,986 ft) of water, involved disconnecting 10 risers/umbilicals; disconnecting 12 mooring lines, and then towing the Innovator to Ingleside, Texas. The company developed special procedures for disconnection and towing, procured rigging and tow equipment for all vessels including the anchor handling vessel, floating production unit, and tug vessels, and provided personnel for the AHV and FPU throughout all phases of operations.

InterMoor’s involvement with theInnovator platform dates prior to 2006 when it was a mobile offshore drilling unit known as the Rowan Midland. At that time, the MODU was being converted by ATP to a production platform, and InterMoor provided the mooring design, project management, procurement, installation, and hook-up of the mooring system. The 12-leg mooring system consisted of suction embedded plate anchors (SEPLA), stud link chain, subsea connectors, and polyester mooring ropes. This was only the third permanent polyester mooring system installed in the Gulf of Mexico and the first permanent SEPLA mooring.

The company’s next assignment on the Innovator was in 2011, providing mooring line inspection, change-out of all rig wires, and upgrading five of the mooring legs due to new Metocean regulations and possible life extension. The company performed the upgraded mooring analyses, provided regulatory interface, and procured the upgrade mooring components.
