Kelvin WHP's infrastructure comprises a minimal-facilities wellhead platform with support for one primary production well and associated Christmas tree equipment. Structurally it consists of a three-leg piled steel jacket and topsides designed to support subsea well completions and flow metering facilities. The platform gathers gas at reservoir pressure and routes it into a dedicated subsea pipeline (~12 km) connected to the nearby Murdoch complex, where further aggregation, metering and processing occurred. Kilometric export pipelines from Murdoch historically carried gas to the onshore Theddlethorpe Gas Terminal via the Caister-Murdoch export trunkline. Utility systems on Kelvin WHP are minimal due to its role as a wellhead host; power generation (small diesel or generator sets) supports lighting, control instrumentation, SCADA monitoring and emergency shutdown systems, while safety infrastructure comprises fire and gas detection, emergency blowdown, and basic offshore evacuation provisions. The platform design focused on robust support for remote operations and subsea tie-backs, with corrosion protection, periodic inspection provisions, and interfaces for intervention vessels to access wellheads and manifolds as needed over field life. Decommissioning programmes have been proposed as part of CMS removal, reflecting the system's mature status while ensuring safe cessation protocols.
