National Oilwell Varco announces contract awarded by BW Offshore for submerged turret production system offshore of Australia.

APL, which is part of NOV’s Completion & Production Solutions segment, has received a contract award from BW Offshore for the supply of a large submerged turret production (STP) system in the Barossa gas and condensate field located offshore of Australia.

Located approximately 300 kilometer northwest of Darwin in the Timor Sea, the Barossa field features water depths ranging between 220 and 280 meter. The Barossa development consists of infield subsea infrastructure tied back to the centrally located floating production storage and offloading (FPSO) vessel. The FPSO processes high-pressure reservoir fluids for gas export to the Darwin liquefied natural gas (LNG) facility via a 290 kilometer long subsea pipeline for condensate storage and offloading.

The Barossa FPSO is a new, purpose-built vessel equipped with our STP system, which provides permanent mooring and connection to subsea facilities. The FPSO is designed for a 25-year life of uninterrupted operation without drydocking.

“Our STP system is a unique, innovative, and flexible turret mooring system for FPSOs. The system includes our STP swivel, which is designed for high pressures, temperature, and volumes, and the system transfers all fluids, signals, and power between the subsea system and the freely weathervaning production vessel,” NOV states in a release.

Hans Hoegh-Omdal, Vice President, Turret, Mooring, & Surf Group for BW Offshore (BWO) commented, “BWO has worked with APL on numerous FPSO projects over the years, the latest being our successful Catcher FPSO project. With APL’s first-class turret technology and our successful cooperation in the past, it was easy for BWO to turn to APL for their assistance for the Barossa project.”
