US-based hydraulic repair, manufacturing, and rental company, Logan Industries, has delivered a custom A-frame to TechnipFMC for one of their new remotely operated vehicles (ROVs), which will deploy later this year in the Gulf of Mexico (GOM).

Logan said the A-frame, which weighs approximately 50,000 lb, is a heavy weather, work-class ROV launching system, designed to move some of the largest work-class ROVs in the market. The A-frame is designed for the ROV and a tether management system (TMS) and can handle 17 MT overboard at a 5.3-m overboard reach. It can also launch and recover large, work- class ROV-TMS combinations in a wide range of sea states.

It has enough room to fully separate the ROV and TMS and stage them both on the A-frame deck, which is fitted with seal-welded drip pans to capture and contain effluent fluids.

Dean Carey, Technical Director at Logan Industries, said, “ … The unique low-reach feature means operators will be able to grab and release the ROV lower than ever before, ensuring safe deployment in rough seas. Operators will be provided with simple controls and enough room to split the system while on deck.”

Logan added that the A-frame is DNV-certified for operations and for lift at 0°C (32°F) and conforms to the following rules: ST-0378; ST-E273 (R-30); SWL [Safe Working Load]: 37,500 lb overboard; and SWL: 31,000 lb luffing.
