Comments

The Pluto project is located northwest of Australia, with first gas scheduled for late 2010. The development will consist of a large onshore LNG plant at the Burrup LNG Park, with 36" flowline from an unmanned riser platform 190 km (118 miles) from shore at 85 m (279 feet) water depth. The drilling center will be located further out at 850 m (2,789 feet) water depth. Subsea equipment from FMC will thus be some of the largest for true deepwater application.

Pluto will utilize the new WEL Gas Tree Standard (GTS), which are conventional 7" trees with 18-3/4" interface to accommodate both workover riser and wellhead. The tree system features a separate flow module with integrated production choke, wet gas meter, MEG injection system and instrumentation.

Pluto will be the first Woodside operated project to utilize FMC’s tie-in system Stabcon. Due to different pipeline sizes, FMC will deliver Stabcon 1 and Stabcon 2 tie-in systems.

Stabcon 1 has been developed for deepwater projects such as Girassol and Stabcon 2 has been developed for larger flowline diameters as for Ormen Lange.
