Culzean Oil Field
Hobbs Valve has been appointed as supplier of a multi-million pound order of TOV (triple offset butterfly valves) to the major Culzean uHP/HT (ultra high pressure / high temperature) gas field. Culzean is located in Block 22/25 of the UK Central North Sea and was discovered in 2008.
The TOV valve is a zero-leakage solution that is versatile enough in service to outperform any other butterfly valve in its class, uni/bi-directionally. This oil field represents one of the largest projects to which Hobbs has ever been appointed.
The valves are being used topside in a standalone facility that will consist of a complex of bridge-linked platforms comprising a 12 slot wellhead platform (WHP), a central processing facility and utilities/living quarters for 100 people. The total investment for the project is expected to be in excess of £3bn (US$4.7bn).
Hobbs’ valves have multiple uses in the oil and gas production industry, such as: isolation of reservoirs and storage; steam piping and condensate; cooling water systems; desalinization; and transport of hydrocarbons.
The development of the Culzean discovery has been made possible by the UK government’s consultation on an extended uHP/HT allowance, reducing taxes on profits from 62% to 30% at current rates. Forecast plateau production at Culzean is expected to be 400-500 million standard cubic feet per day.
