Angel
The Angel platform – the North West Shelf Venture’s newest offshore gas production facility – is located about 120 km north-west of Karratha.
The remotely operated platform is tied in to the first trunkline at the North Rankin A platform via a 50 km subsea pipeline and is designed to allow for the tie-back of other discoveries in the area.
Angel stands in about 80 metres of water and is supplied by three subsea production wells. Its unique design enables it to be safely and securely powered and remotely controlled from North Rankin A via a subsea cable.
Hydrocarbons are produced through one ‘dry export’ processing unit with a daily capacity of up to 22,200 tonnes of gas (800 million standard cubic feet of raw gas) and up to 50,000 barrels of condensate, and are processed onshore at the Karratha Gas Plant. The Angel Platform achieved unmanned status in 2009.
Also in 2009, the Angel Platform was named overall winner of the WA Engineering Excellence Awards. It Also recieved a National Engineering Excellence Award.
