The latest letter of intent awarded from the Chiyoda JGC JV is for the fabrication and construction of the topsides for the PNG LNG condensate offloading jetty.

The contract is valued at around $US53 million and follows the recent $US258 million contract awarded for the design and construction of the offloading jetty.

Under the latest contract, the JV will fabricate and assemble the topsides at Clough's Sattahip Fabrication yard in Thailand before transporting and installing them at the jetty site, 20 kilometres northwest of Port Moresby.

"Clough and our long-term partner BAM International are delighted to be given the opportunity to deliver our topsides for the EPC project, which will provide continuity of quality of work for our yard in Thailand," Clough chief executive officer John Smith said.

The BAM Clough JV is a 50:50 JV between BAM International and Clough.

First production from the two train 6.6 million tonne per annum PNG LNG project is expected in 2014.
