Arup to engineer Indonesian LNG project

ENERGY World Corporation has awarded an engineering contract for its Sengkang liquefied natural gas plant being built in Sulawesi, Indonesia, to Arup Energy.

Arup will provide LNG storage, ship loading, maritime and civil engineering services for the project, which will be Energy World's second LNG facility and the first plant configured using modular liquefaction components.

The facility will have a capacity of 2 million tonnes per annum built from 500,000tpa units.

The project will include development of Arup's patented concrete storage tank.

The tank eliminates the need for a liner in the primary container and utilises a simple and cost-effective water vapour barrier on the tank secondary wall.

Arup Energy business leader Brian Raine said the company achieved savings through design, simplicity and speed of construction.

"We avoid the long lead time associated with proprietary liners, membranes and 9 percent nickel-steel. Construction is less reliant on participation of specialist subcontractors," he said.

Civil construction group Slipform Engineering will construct the tank and Arup will provide all engineering documentation.

The LNG plant is expected to be operational by the end of 2009.
