Halfdan CA comprises well slots and manifold headers for production wells, with minimal processing. It sends hydrocarbons via subsea flowlines and riser ties to the Halfdan B complex for main separation, dehydration and export conditioning. Remote power and communications are supplied through the host, with safety shutdown and flow assurance systems integrated into the Halfdan hub's process controls. Export infrastructure routes gas predominantly to Tyra West and oil via established pipelines to Gorm and Dan installations. Stable features include fixed jacket supports, subsea tie-backs, corrosion protection, and remote instrumentation.
