Manual gate valve for topside applications

21 July 2021

The recently qualified Oliver Valves ½” bore topside manual gate valve has provided its client a solution for use in an industry first high-pressure development in the Gulf of Mexico. The project required 20ksi DBB Isolation for vents, drains and chemical injection points around the TUTA (Topside Umbilical Termination Assembly), boarding valves and production manifold. 

Process operating pressures were expected to be around 16,500psi. A fully rated API 20k valve was required by the customers’ specifications. Small bore instrumentation needle or ball valves were available to the customer at working pressures of 20,000psi but a full through bore gate valve, such as the one above, was a new market requirement.

As the supplier of choice, Oliver’s were required to design and build a valve very quickly to meet the stringent application and also the project time-line. All of the considerations below had to be met: conceptual design and engineering calculations, size & weight considerations, FEA Analysis , Fire Testing et cetera.

Oliver Valves team was able to meet and exceed all of the customers’ requirements. Collaboration with the customer from an early stage in the project resulted in a mutually beneficial solution.
