Engines for World’s First Elevating Support Vessel

Remedial Offshore announced the purchase of V228 medium-speed diesel engines from GE Marine, Erie (USA). The engines will be used to power the new Remedial Offshore Elevating Support Vessels™ (ESVs). As the world’s first self-propelled, 325-foot/100-meter nominal water depth-rated jack-up well intervention vessel, Remedial Offhore’s ESV™ design provides a hybrid between a jack-up drilling rig and a marine vessel. The new ESV concept offers tremendous versatility and operational functionality, ranging from an incorporated electric well workover package to a large open deck for offshore support functions.

Each vessel is uniquely outfitted to provide a stable work environment for deploying today’s most advanced well intervention or production enhancement technologies. ESV abilities include well workovers, sidetracking, well abandonment, facility upgrades, brownfield rejuvenation projects and small field developments, as well as providing complete services for well intervention. The GE engines meet Remedial Offshore’s design and operational criteria, such as the ability to have sufficient power available with a minimal number of engines in the existing space, while ensuring adequate redundancy.


Remedial Offshore’s ESV technology provides stable offshore work platforms specifically designed and purpose-built to support remedial oil and gas activities and applications. The Remedial Offshore ESV concept is fully compatible with advanced well intervention technologies and facilitates mature field rejuvenation. Each Elevating Support Vessel:
Allows global deployment in a vast number of mature basins;
Can work in nominal water depths to 325 feet/100 meters;
Is self-propelled (7 knots), eliminating need for tugs or anchor-handling vessels;
Can carry more than 3,000 tons/2,722 metric tons of variable load;
With a high-capacity (308 tons/280 metric tons) pedestal crane on a traversing gantry that does not obstruct equipment on the large, open deck (~10,000 ft2/930m2 );
Is self-elevating, which enhances safety, extends the “weather window” in which it can operate, and optimizes its onboard crane lift capabilities;
Includes an electric 500-kip “doubles” workover rig; and
Benefits from numerous proprietary design features.
