U.S. Patent 9,745,816
The Riserless Open-Water Abandonment Module (ROAM) is the Subsea Services Alliance solution for environmentally friendly production tubing removal in open water. When run as a complement to the Intervention Riser System (IRS) or Subsea Intervention Lubricator (SIL), ROAM enables the ability to capture contaminants or gas within the system and circulate them back to the safe handling systems on board the vessel. By doing such, high confidence is gained that nothing unwanted is released into the environment. The 18 3/4” Full Bore ID allows for the ability to pull tubing hangers through the ROAM to surface.
The ROAM has two barriers capable of shearing and sealing landing strings and production tubing that will pass through the system during recovery.
