DUBAI, UAE – Drydocks World will build the turret for Shell’s (RDS.A:NYSE) Prelude floating LNG project offshore Western Australia. What will be the world’s largest marine turret is being built under contract with SBM Offshore N.V. (AMS:SBMO).
The Drydocks work scope includes fabrication and load-out of six modules that will constitute the internal turret. SBM will provide the design, material, and equipment under its contract with a Technip/Samsung Heavy Industries consortium.
The turret will be 30 m (98 ft) in diameter, 90 m (295 ft) tall, and weigh 11,500 metric tons (12,677 tons). The FLNG vessel will measure 488 m (1,600 ft) in length and weigh about 600,000 metric tons (661,397 tons) when loaded.
The facility design calls for the vessel to weathervane in response to weather conditions and is being designed to withstand a Category 5 storm.
