Oliver Valvetek Double Gate Valves on the Norwegian Continental Shelf
Oliver Valvetek has manufactured a number of 1 ” Double Block Subsea Gate Valves with manual and hydraulic actuation destined for the Norwegian Continental Shelf ( NCS ).
This dual functioning valve consists of a 1 ” hydraulic gate valve and a 1 ” multi-turn manual Gate valve both positioned on a single unitary forged valve block for dual redundancy and functionality . This unique and customised design brings additional benefits to subsea tree engineers in that it now provides flexibility to be used as stand-alone and fully functioning valves on other applications of the tree due to its standardised valve footprint .
To date , Oliver Valvetek has manufactured more than 150 double gate valves with the hydraulic gate valve being a coil spring design as specified by the end-user .
Interestingly , a continental shelf is a shallow and relatively flat stretch of seabed that extends from the shoreline to water depths of around 200 metres , before dropping off to deeper waters in what ’ s called the continental slope .
The importance of the continental shelf to Norway is that it holds huge natural resources such as oil and gas , but also fishing . The bestknown fishing areas are found on the Shelf and at the edges where it meets the deep sea . Under international law , coastal states are entitled to their continental shelf up to 200 nautical miles from their shores with some exceptions made to lengthen this , with NCS being one .
