Intro
The Syd Arne Wellhead Platform North (SA WHPN) is a fixed steel jacket satellite in the Danish North Sea, commissioned in 2013 to support the South Arne oil and gas field. It serves as a production gathering node with wellheads routed to the main South Arne host for processing and export. Water depth is ~60-m.
Field
The South Arne (Syd Arne) field in Blocks 5604/29 & /30 produces crude oil and associated gas from Danian and Upper Cretaceous chalk reservoirs. Discovered in 1969, production began in 1999. The field comprises a central platform with bridge-linked satellites for well access and export integration to tanker and pipeline systems.
Facilities
Syd Arne WHPN comprises well slots drilled into chalk reservoirs, collecting fluids for transport to the central South Arne processing platform (SA) via bridge or short tie-backs. It hosts wellhead manifolds, flowlines and subsea isolation systems; no primary processing occurs onboard. Oil and gas are routed to the SA main platform where multiphase separation, emulsion breaking, and gas compression occur before export. Oil is stabilized and then exported using a subsea oil export system and single anchor leg mooring (SAL), while gas is sent ashore via a long-distance export pipeline to Nybro. Utilities on WHPN are limited to power distribution and control systems linked to SA; there is no accommodation module. Safety systems include emergency shutdown valves, fire and gas detection, and remote monitoring. Stable features include fixed jacket structure with corrosion protection, well control systems, and pipeline/riser support.
