The Subsea Services Alliance, a collaboration between Helix Energy Solutions Group Inc. and Schlumberger, have launched development of the first riserless open-water abandonment module (ROAM).

In a news release, Schlumberger said the 18¾-in. large bore system will enhance well abandonment capacity from a well intervention vessel by allowing tubing to be pulled in open water in a safe and environmentally contained manner.

The ROAM system, which will be engineered and built at the OneSubsea’s Aberdeen manufacturing facility, is expected to be available in third-quarter 2017.

“We are taking this step in response to a market requirement to lower the cost of subsea abandonment that is impacting our customers globally,” Mike Garding, president at OneSubsea, a Schlumberger company, said in a news release. “The ROAM system will extend our capability into true lower completion abandonment and also reduce the uncertainty of well integrity that our customers face when they proceed to upper completion abandonment operations.”
