AME’s premium ILSC, The Colossus, is the primary motion compensation system required for operation.

01 Capability

AME was initially contracted through Transocean to provide 2x primary motion compensators and Tension Lift Frames for the completions and well testing of the Gorgon Stage 2 wells onboard the Transocean Development Driller 1.

The primary motion compensation system is required during locked to bottom operations to solve ton-mile issues inherent in active heave draw works systems. Extended locked to bottom campaigns and high string loads can often exceed the allowable ton-miles for the draw works wire causing possible fatigue failure in the wire.

A simple yet innovative, primary passive compensation solution

The system comprised of a 500ton primary motion compensator that is fully self-contained allowing minimal deck space for support equipment, as well as significantly reducing rigup time on critical path. The design also removes any requirement for high pressure & high flow gas lines in the derrick and external deck mounted accumulator banks.

The Colossus compensator connects to a modified 500ton AME Tension Lift Frame system to allow the required wireline operations for the completions and well testing.
