Malaysian offshore fabricator Ramunia has won a $26.4 million job to build the 4000-tonne platform topsides for Woodside Petroleum's Pluto gas project in Australia.

Ramunia said in a statement to the Malaysian Stock Exchange that its workscope comprises the engineering, procurement, construction, commissioning and load-out of the riser platform topsides.

The Pluto platform will feature minimal facilities to minimise the operation and maintenance burden.

It will have no processing capability, and will feature multiple risers and J-tubes for production and compression.

The platform will be connected to five subsea big bore wells on the Pluto field, with first gas to be produced in late 2010.
