DEEPSEA
Deep Sea Systems
Flexible pipeline systems engineered for deepwater offshore developments where corrosion resistance, fatigue performance, and installation efficiency are critical. FPS deep-sea RTP, TCP, and flexible pipeline systems connect subsea infrastructure such as PLEMs, subsea trees, and manifolds to floating production facilities including FPSOs, FSOs, and Tension Leg Platforms.
All FPS deep-sea RTP and TCP systems are manufactured and qualified to API 15S, API 17J, and API Q1 standards with full traceability, inspection, and fatigue testing under ISO 9001, ISO 14001, and ISO 45001 systems. With annual production capacity exceeding 7,000 kilometres of pipe, FPS global manufacturing capability delivers reliable offshore pipeline systems for major energy developments worldwide.
