UAE-based support vessels provider Gulf Marine Services (GMS) has announced the completion of the first well intervention workscope, using its cantilever workover system.

The deployment of cantilever technology is part of a contract for an undisclosed national oil company (NOC) client in the MENA region.

For the first time, the GMS-developed cantilever system has been used on a live well.

The technology reduces the time required for vessel moves and enables safer operations.

Jack-up vessel GMS Evolution carried out the work.

GMS executive chairman Tim Summers said: “GMS is the only company in the world with this SESV technology.  We are able to provide our clients with safe, innovative cost-saving technology solutions to enhance their oil and gas production, which is ever more valuable in these challenging times.

“The cantilever system onboard Evolution is capable of carrying out aspects of well workover activity normally conducted by a drilling rig; however, its real strength comes when frequent moves within the field are required.

“Being self-propelled, and unlike a drilling rig, the vessel does not rely on tug support so can move between locations at a fraction of the time a drilling rig requires. This offers significant cost and time savings to our clients for a well intervention programme. We look forward to developing this technology to its full potential.”

Other operational advantages of the cantilever technology include the elimination of lifting over live wellheads, a reduction in well-intervention time, a radical improvement in transfer platform-to-platform times over conventional rigs, and further cost savings.
