ABS approves GMS cantilever system for SESV


GMS has received ABS approval and certification of its cantilever system for GMS Evolution, a self-elevating support vessel (SESV) delivered in May this year.

ABS provides classification and technical services to the offshore industry.

GMS Evolution is equipped with a small removable skidding cantilever system, installed with a well workover unit (WOU) designed in collaboration with Dwellop.

“This system offers cost-effective solutions for work that has traditionally been performed by more expensive non-propelled drilling rigs.”

ABS Middle East regional vice-president Darren Leskoski said: “As a technology leader, ABS is thrilled to be working with enterprising partners such as GMS as it develops and launches assets with increasingly greater capabilities and flexibility.

“GMS Evolution represents a milestone for GMS in attaining innovative efficient solutions for well intervention and workover.”

The combination of a self-propelled jack-up with a removable cantilever and workover unit is claimed to be one of the first of its kind to be used for well intervention.

The cantilever system acts as a versatile vessel for well services while the WOU can be skidded over a platform or subsea well.

GMS Evolution is capable of accommodating 150 people besides featuring multi cranes, including one of 200t capacity and DP 2 positioning.

GMS CEO Duncan Anderson said: “Our new cantilever system will give clients a range of options in the way they use our barges to service their offshore assets.

“This system offers cost-effective solutions for work that has traditionally been performed by more expensive non-propelled drilling rigs.”

Based in Abu Dhabi, UAE, GMS manufactures and operates a fleet containing 14 SESVs in which GMS Evolution represents the final vessel of its seven DP 2 GUSTO designs.
