The Seawell is a DP2 light well intervention and saturation diving vessel which features a purpose built Module Handling System (MHS) tower positioned over a 7.0m x 5.0 m moonpool.
The unique design and multi-service capability significantly reduces intervention time and provides a cost-effective method of maintaining subsea well stock, through well maintenance and production enhancement solutions.
Its track record is second to none, having intervened in more than 700 wells, decommissioning over 200 live and suspended wells, including 15 subsea fields.
The main winch is rated to 150 Te (SWL) hookload capacity in both passive or active heave compensation modes. The tower also incorporates guide wire tensioners and winches, active and passive podlines and constant tension Launch and Recovery System (LARS) winches.
The Seawell’s MHS is capable of deploying both 5” and 7” SIL systems to 500m water depth. This includes the 73/8” Electro-Hydraulic SIL which enables communication with next generation Subsea Trees.
The subsea crane provides an AHC lifting capacity of 45Te. Inbuilt vessel tanks provide generous storage for chemical treatment (pumping) capabilities.
