What is an ESV™ unit? Elevating Support Vessel (ESV™) units are self-propelled jack-up well intervention vessels rated for service in 325 ft (100m) water depths, carrying a dedicated electric workover rig.
Remedial Offshore's innovative ESV™ concept offers offshore oil & gas operators a unique way to combine the capabilities of jack-up rigs with the self-contained efficiencies of ocean-going vessels. Our robust ESV™ units improve the logistics and economics of conducting remedial work offshore.
Our unique vessels provide 14,000 ft2 (1060 m2) available deck area for equipment rig-up, plus a high-capacity pedestal crane (300-ton/280 MT) mounted on a moveable structure. With structure stand-off and longitudinal travel, the ESV™ main crane can place 110-ton (100 MT) loads at 158 ft (48 m) from the vessel's transom.
The 250-ton (227 MT) modular electric “doubles” workover package is fully deployable (in either tender-assist or cantilever-supported mode) within three crane lifts for faster rig-up.
Accommodations for 120 individuals are available in 4-person suites, semi-private or private rooms, so ~94 customer or third-party contractor personnel can be housed onboard (in addition to the ESV™ crew). Available deck area combined with ample onboard accommodations makes each of our ESV™ units ideal mobile platforms for supporting simultaneous multi-well intervention programs and 24/7 operations.
