Project Profile
Value: US$4,000 Million
Startup Year: 2016
Upstream Gas Reserves: 2,500 billion ft³
Upstream condensate reserves: 120 million boe
LNG: 3.5 million tonne/year
Water Depth: 250m
Block WA-371-P lies in water depths of between 200 metres and 300 metres and is next to Inpex\'s Ichthys gas and condensate fields. The project will see the drilling of eight production wells over a period of two years. The wells will be tied back to manifolds and connected to the FLNG vessel through four flowlines. The Prelude gas field has 2.5-3 Tcf (70.8-84.9 Bcm) of gas and around 120m bbl of condensate. The project will have the world’s first FLNG facility with a capacity to produce 3.5 million tons of LNG a year.
Operator:
Shell Australia Ltd.: Operator with 100% interest
Contractors:
Technip Samsung Consortium: FEED for FLNG & Subsea installation contract
Songa Offshore: Drilling rig
SBM Offshore: Internal turret
FMC Technologies: Subsea production and topside systems
Rolls-Royce: Provision of three Rolls-Royce electrically powered USL 455 azimuth thrusters at the Samsung Heavy Industries shipyard in Geoje, South Korea. Rolls-Royce teams in Norway, Finland, Korea and the UK were involved in tailoring the solution specifically for Prelude. To facilitate thruster overhaul or replacement while at sea, each electrically-powered thruster is located at the base of a purpose designed trunk which links to the higher workshop area with its dedicated cranage. Thruster condition monitoring system (CMS) is also part of the Rolls-Royce supply.
Samsung Heavy Industries: Construction and fabrication of the azimuth thrusters supplied by Rolls-Royce in shipyard in Geoje, South Korea
ABB: Five-year contract to deliver equipment and services for Shell’s Prelude FLNG, the world’s first floating liquefied natural gas (FLNG) facility, the largest floating facility ever built. ABB’s equipment will minimize downtime and optimize the efficiency of the facility. The order includes the delivery of motors, generators, variable speed drives and low-voltage switchgear and guarantees service and lifecycle management of the electrical equipment as well as service and support for motors from third-party vendors. ABB will build up a spare parts inventory, workshop repairs, training and provide round-the-clock technical support both over the phone and on-site. Spare parts and replacement systems are being procured this year, with training to begin soon after. Prelude is 488 meters long, 74 meters wide, with a loaded displacement of 600,000 tons with the facility’s deck longer than 4 football fields laid end to end. (March 2016)
