Sapura Well Services' Intervention Compensation System (ICS) is a modular frame which provides four guide wires and a compensated deployment sheave to enable the deployment of umbilicals and tools to the subsea well. This field proven system was designed and built under full DNV survey and classed as an offshore crane.

The ICS is designed to be installed onto a work vessel that has a heave compensated crane sufficiently rated to deploy the intervention lubricator packages. The modular frames have been developed for ease of road transport and shipping, and can be loaded to a vessel with a single lift during mobilisation.
