The work, conducted in water depths of 910m, involved disconnecting 10 risers/umbilicals, disconnecting 12 mooring lines and then towing the Innovator to Ingleside, Texas.

InterMoor developed special procedures for the disconnection and towing, procured rigging and tow equipment for all vessels including the anchor handling vessel, floating production unit and tugs.

It also provided the essential personnel for the AHV and FPU throughout all phases of the operation.

InterMoor's involvement with the Innovator platform dates back to 2006 when it was a mobile offshore drilling unit known as the Rowen Midland.

At the time the MODU was being converted by ATP to a production platform.

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.

It was leading-edge technology at the time as it was only the third permanent polyester mooring system installed in the GoM and the first SEPLA mooring.

InterMoor's next assignment on the Innovator was in 2011 when it provided mooring line inspection, changed out all rig wires and upgraded five of the mooring legs to meet Metocean regulations and possible life extension.

It also performed upgraded mooring analyses, provided a regulatory interface and procured the upgraded mooring components.

Therefore, InterMoor had a detailed understanding of the Innovator's mooring system, which made the decommissioning program that much easier.
