Arup Energy appointed to engineer Sengkang LNG Project

Global design and consulting firm Arup Energy said it has been appointed by Energy World Group to provide LNG storage, ship loading, maritime and civil engineering services for the proposed Sengkang LNG liquefaction facility to be built in Sulawesi.

The Sengkang project 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 tons per annum built from 0.5 million tons per annum units, the company said.

The project will include development of Arup's All Concrete Liquefied Natural Gas (ACLNG) storage tank for the 80,000 cubic meter capacity full containment tank.

Arup and the Energy World Group have been working together since signing an agreement in 2001 to jointly develop and deliver the innovative storage tank solution. The Sengkang project is the first Energy World project application.

Arup developed the storage tank solution after completing a systematic review of existing cryogenic storage tank technologies to identify improvements in cost and construction schedule. The review concluded that fundamental changes to the use of materials were necessary to simplify the construction process and realize cost and schedule savings.

The tank eliminates the need for a liner in the primary container and utilizes a simple and cost-effective water vapor barrier on the tank secondary wall. Construction relies on well-established civil engineering technology that is available anywhere in the world.

The tank will be constructed by the civil construction group, Slipform Engineering (Hong Kong) Limited. Arup Energy will provide all engineering documentation. The storage tank will be constructed in less than 24 months. The plant will be operational by end of 2009, the company said. (denny)
