ROAM

Riserless open-water abandonment module

Developed through the Subsea Services Alliance with Helix Energy Solutions, the riserless open-water abandonment module (ROAM) is an environmentally friendly tubing removal in open water solution. When run as a complement to the intervention riser system (IRS) or subsea intervention lubricator (SIL), ROAM enable the ability to capture contaminants or gas within the system and circulate them back to the safe handling systems on board the vessel.

The 18 3/4-in fullbore ID enables pulling tubing hangers through the ROAM to the surface. ROAM has two barriers capable of shearing and sealing landing strings and production tubing that will pass through the system during recovery. ROAM also provides an additional barrier on the well when running current technology into the well to perforate and inject or circulate cement.
