GMC ICPTM lowering SyStem

GMC ICPTM Lowering System, has been designed for installation of subsea modules, the system uses GMC’s patented ICPTM Connection system for deploying the hard-ware to the seabed. The system can be used for safely lowering modules such as PLET’s PLEM’s Manifolds, and general subsea hardware from any crane barge or vessel of opportunity in deep water hostile environments.

The GMC ICPLS system offers fast deployment, using high fatigue, quick connect snaplay connector’s on light weight high strength tubular. Once in position the subsea module is released and the deployment system is recovered to surface and ready for the next deployment. Reducing installation time and cost, and enabling large heavy modules to be lowered safely in a controlled manner in deep water applications. See overleaf for installation sequence.

• Tension = 2000 MT up to 3000M Water Depth

• Weight in Air = 5.6mt/50m• Weight in Water = 3.7mt/50mt• Connection Type = GMC Connector

— high-fatigue, — non-rotational, — quick connect.
