P11-B-De Ruyter's facilities centre on a robust GBS with an integrated production deck that supports oil separation and storage, gas handling, produced-water treatment, and power generation. Oil from multiple wells is processed, stabilized and temporarily stored within the GBS before periodic export via a TMLS to shuttle tankers. Gas from the field is compressed and exported via an ~8-inch pipeline to the TAQA operated P15-D platform, and onward into onshore gas networks. Subsea tie-backs such as Van Nes and Van Ghent have been developed via subsea flowlines and control umbilicals, integrated into De Ruyter's processing system as part of the Medway development. The recent Unity project (P11-Unity) adds a minimum-facilities wellhead platform tied back for gas from Witte de With and Van Ghent East, routed to De Ruyter. Topside utilities include power generation (typically diesel/gas turbines), produced water and hydrocarbon handling, safety and fire systems, flare and vent systems, and accommodation modules. The GBS design provides stability in ~33-34-m water depth; stable features include subsea control systems, export metering, and robust structural integrity measures for long-term operation.
