Oil & Gas

GMS operates the largest independent self-elevated support vessel (SESV) fleet in the MENA region and is the largest in the world. We charter our SESVs to a high quality client base comprising leading NOCs, oil majors and broader oil and gas services companies operating in the MENA region and northwest Europe, for use as customised work platforms for offshore oil and gas construction and well maintenance services. (We also charter our SESVs for use by leading offshore renewable energy companies to support their construction and maintenance of wind farms.)

Our vessels support our clients in two principal areas that span the lifecycle of shallow water offshore oil and gas fields (and offshore renewable energy projects):

Opex Activities, which we define as brownfield projects, operations, maintenance and modifications, with respect to both oil and gas and offshore renewable energy projects, as well as well servicing retrofit or upgrade activities with respect to oil and gas assets. These activities are typically funded out of our clients’ operating budgets.

Capex Activities, which we define as greenfield projects, engineering, procurement and construction activities, installation and decommissioning with respect to both oil and gas and offshore renewable energy projects and, with respect to enhanced oil recovery activities, water injection and gas injection. These activities are typically funded out of our clients’ capital expenditure budgets.


Key advantages of the self-propelled jackup over conventional barges include:

Independent: Dynamic Positioning (DP2) allows the vessel to move under her own power with high accuracy positioning alongside a platform.

Fast: The vessel can move faster than conventional jackups between locations due to higher transit speeds of six knots and by not requiring anchor deployment.

Flexible: GMS is both builder and operator and can adapt/configure the vessel to clients’ requirements, with the vessel able to move easily between oil and gas operations to wind farm installation and maintenance contracts.

Safe: Day-to-day work is free from the added hazards a moving vessel introduces. A safer working environment for large numbers of offshore workers.

Comfortable: The four-legged design provides a stable platform for those living on board; the efficiency of a man well-rested in a stable bed is greater than someone trying to sleep on a moving vessel (for crew and non-seafarers).

Convenient: Two gangways installed in combined operations provide an effective solution for top side maintenance on a smaller platform.

Cost effective: The weather window for a conventional jackup barge to move in-field is an average of three days; GMS’ self-propelled jackups can do it in a few hours. No need for tug support/anchor handling. Fuel-efficient.
