GMS teams with Dwellop for well intervention, workover services

Offshore staff

ABU DHABI, UAEGulf Marine Services (GMS), a specialist in self-propelled self-elevating support vessels (SESVs) for offshore construction and other services, has formed a partnership with Norway-based Dwellop.

The latter, formerly owned by Rolls-Royce Marine Engineering provides topsides handling systems for well intervention and workover operations.

The partnership will offer a cantilever system for the vessels that should provide GMS’ clients with alternative solutions for work traditionally been performed by more expensive, non-propelled drilling rigs.

GMS operates typically on mature oil fields where drilling rigs undertake a large volume of workover activity. The company claims its vessels can move more quickly between surface wellheads and adding the cantilever solution should lead to cost savings and further reductions in non-productive time.

According to Dwellop CEO Helge Hustoft, “The technology is proven and was developed for the harsh environment of the North Sea. The first rig was delivered to Talisman. This new partnership with GMS marks the first step of our growth strategy to enter into new markets globally.”

The partners have entered into a three-year exclusive agreement for cantilever solutions for the GMS SESVs, with the first two systems due to be delivered this year.

The first will be for well intervention with wireline and coiled tubing, while the second will be equipped with the workover rig. Capabilities will include P&A, light drilling, change out of submerged pumps, and completions.
