Shell’s Prelude FLNG gets Lloyd’s Register classification

  • Vessels

Shell’s floating liquefied natural gas (FLNG) facility Prelude has officially entered into Lloyd’s Register class.

At 488 metres long, 74 metres wide and displacing about 600,000 tonnes of water, Prelude is the largest floating offshore facility in the world, Lloyd’s Register said on Wednesday.

Last month Prelude arrived at its operating location in the Browse Basin, offshore northwest Australia. It has been connected to all of its 16 mooring lines at the Prelude field, 475km North-North East of Broome and will not be dry-docked for the first 25 years of its expected 50-year operational life.

The Prelude FLNG facility will produce 3.6 million tons per annum (mtpa) of LNG, 1.3 mtpa of condensate and 0.4 mtpa of LPG.

The project will be operated by Shell in a joint venture with Inpex (17.5 percent), Kogas (10 percent) and OPIC (5 percent).

Lloyd’s Register said it has been actively involved with the project from the start, helping to ensure it will operate safely by applying FLNG expertise through classification, equipment certification, validation and verification against performance standards.

Prelude’s substructure and turret have been designed and constructed in accordance with LR’s Rules for Floating Offshore Installations at a Fixed Location and its topsides certified to an agreed set of industry codes and standards.

LR also confirmed compliance of the facility with Shell’s design and engineering practices, where applicable, and the performance standards specified by Prelude’s safety case.

The intended risk based classification scheme is expected to benefit from the use of the latest in remote inspection technologies to gather accurate and repeatable survey data to allow a predictive and focused approach.

The LR team in Perth will be welcoming colleagues from LR’s Geoje office in the coming months to assist in the transition from the yard through offshore commissioning to the operations phase, the classification society said.
