Ringhorne

The Ringhorne installation is a wellhead platform in the central Norwegian North Sea serving the Ringhorne Øst field, installed in the early 2000s to produce oil with associated gas. It ties into the Balder FPSO for processing, storage and export, without standalone major processing on the platform itself.

Field

The Ringhorne Øst field lies ~6-km northeast of Balder in the North Sea, producing oil from Jurassic sandstone reservoirs with natural aquifer support and gas lift. Discovered in 2003, it started production in 2006.

Facilities

The Ringhorne platform functions primarily as a dry wellhead facility with multiple production wells tied back to the Balder FPSO for primary separation, storage and export. There is no extensive separation or compression plant on the platform; instead, wellstreams are routed via subsea flowlines and risers to the Balder floating production vessel where processing and export operations occur. Utilities on Ringhorne include power distribution (often via a connection to Balder systems), emergency shutdown and safety systems, corrosion protection, and subsea control modules for well and flowline management. Produced oil flows through the FPSO's storage and offloading systems onto shuttle tankers, while any associated gas may be exported through linked networks or used for injection. Structural design emphasises wellhead integrity and riser support for safe fluid transfer in the North Sea environment.
