Well Intervention // Seawell

Since 1987, the monohull MSV Seawell has served as a pioneer of the Light Well Intervention industry throughout the North Sea.

The DP2 Seawell’s 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.  The vessel’s track record covers more than 650 wells, decommissioning over 150 live and suspended wells including 5 subsea fields.

Seawell features a purpose built derrick over a 7m x 5m moonpool and has a travelling block rated to 80Te capacity in passive mode.  The vessel’s derrick is equipped with guide line tensioners, a subsea wireline lubricator winch, and both active and passive compensation.

Seawell’s twin bell saturation diving system is rated to 300m and has capacity for an 18-man dive team. The diving spread, combined with the vessel’s observation class ROVs, provides for full IRM and light construction services.

Seawell’s  versatility is one of the biggest attractions for users of the vessel. Seawell can flow (and flare) hydrocarbons back to surface, conduct complex chemical pumping operations, fully abandon a subsea field, and have saturation divers working on the seabed, quite often simultaneously with wireline operations.
