This field proven system was designed and built under full DNV survey and classed as an offshore crane.
The ICS comprises two separate H-frames, each with two hydro-pneumatic guide wire tensioning systems, which can be deployed over a vessel’s moonpool or over the side/stern. The 5 m3 air receivers allow the wire tension to be quickly and easily adjusted between 0-6 tonnes. The heave compensation system is installed in one of the frames and can be engaged and disengaged remotely. The system provides heave compensated deployment of subsea and down-hole tooling when teamed with a suitable winch.
Each H-frame can be skidded independently, increasing or decreasing the size of the moonpool opening. This is also beneficial for deepwater applications as the two unitised frames can be mounted at a larger spacing to facilitate separation between umbilicals and wire line activities and reduce the risk of entanglement.
The ICS is designed to be installed onto a work vessel that has a heave compensated crane sufficiently rated to deploy the intervention lubricator and/or other 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.
