Intro
Ravenspurn WT1 is a steel jacket wellhead tower installed in 1990 on the Ravenspurn North field in the Southern North Sea, Block 43/26a. It provides wellhead support and tie-in functions for the central processing complex. WT1 is bridge-linked to the main concrete gravity base CPP and supports dry gas production.
Field
WT1 is part of Ravenspurn North, a Permian Leman/Rotliegend sandstone gas field discovered in 1984. The field’s development includes a central CPP with compression and processing, bridge-linked WT1, and satellite platforms ST2 and ST3 feeding into the CPP.
Facilities
WT1 hosts multiple wells producing gas to the adjacent Ravenspurn North CPP. Its steel jacket structure is connected by a bridge to the concrete gravity base CPP and accommodates wellheads that feed directly into the central slug catcher and separation headers. The CPP handles major processing functions — two-stage three-phase separation, glycol dehydration, compression trains for high and low pressure gas, metering, and export system tie-ins. Gas from WT1 and satellites is routed through the CPP slug catcher and processed within the separation and dehydration trains before export via a 24-inch pipeline to the Cleeton hub. Condensate from separators is co-exported with gas; water is treated and discharged overboard to required standards. WT1’s design supports integration of well control, emergency shutdown, and electrical tie-backs to CPP power generation and utility systems, enabling centralized operations while providing robust wellhead support close to the processing heart of the field.
