Trendsetter completes subsea well incident containment system

Offshore staff

Trendsetter Engineering has completed work on a containment toolkit that can be deployed to minimize the environmental impact of a subsea well incident.

The toolkit works alongside standard industry well test hardware (i.e. vessels, well test equipment, drilling riser, BOP, inner string, coil tubing unit), incorporates items generally considered to require long-lead times, said Trendsetter.

Also included are a flowline end termination; side-entry flow spool with subsea test tree latch; diverless subsea connectors; coiled tubing termination head; chemical distribution assembly; deployment reels for flying leads; flexible jumpers/flowlines; topsides transfer pumps and coolers; hose end valves; and offloading hoses.

In cases where a well cannot be shut in, the containment system can be used to flow hydrocarbons from a subsea well to the surface for storage and disposal. During a response, it can be assembled in one, two, or three containment legs as needed.

Trendsetter said the toolkit will be stored in strategic locations to facilitate timely response worldwide. Its flexible subsea jumpers and subsea flowlines are too large to be transported by air, so three sets will be stored in the UK, Brazil, and Singapore for onward transit.

The equipment will be owned by OSRL and will be made available to all operators worldwide on a subscription basis.
