July 16, 2019

Congratulations to Shell on its achievement of first shipment of liquefied natural gas, which sailed from the Prelude Floating Liquefied Natural Gas (FLNG) facility on June 11, 2019.

SBM Offshore designed and built the turret and mooring system, which ensures that Prelude can operate safely in the most extreme weather conditions.

Editor’s notes:

  • The turret runs through the front of the facility and connects to chains that keep it moored securely over the Prelude gas field.
  • At 93 metres (305 feet), the turret runs through the facility, secured to the seabed by mooring lines.
  • Safety in design: with the turret, Prelude is designed to withstand a 1-in-10,000-year storm.
  • Prelude FLNG is moored in the Browse 475km north-north east of Broome in Western Australia, in about 250 metres of water and will operate for around 25 years.
  • Dimensions of Prelude FLNG: 488m length, 74m width and 93m height (top of the turret)
