Aberdeen based Interventek Subsea Engineering is launching a new Open Water Well Control Valve at the forthcoming Offshore Technology Conference (OTC) in Houston (1st-4th May 2017). Designed for Light Well Intervention (LWI) and workover operations, including large bore, deep water and HPHT applications, this shear and seal valve brings a new class of well control equipment to the market.
Utilising a newly developed, linear form of their patented revolution technology, Interventek’s open water well control valve provides critical safety protection during LWI, particularly in emergency disconnect situations. It can cut through obstructions and immediately provide bi-directional sealing protection at full working pressure. The use of resilient seals for fluid containment avoids the risk of rapid gas decompression. The uniquely separated cutting and sealing mechanisms within the valve means that, unlike other products, such as gate valves, its sealing surfaces are protected during cutting.
The new valve has been designed to exceed the standard cutting capability of wireline/ coiled tubing class shear and seal products. It is able to shear slickline, braided cable, coiled tubing and notably 2” sinker bar.
The open water well control valve is the third of Interventek’s ingenious applications of its patented revolution technology.
