OWNER: ExxonMobil CLIENT: Chiyoda JGC Joint Venture EPCMJoint Venture:

BAM Clough Joint Venture is a 50 / 50 joint venture between BAM International bv and Clough Limited. Established in 1964, the joint venture has successfully delivered 13 major jetty projects for the energy and resources sectors.

Scope of Work:

In August 2010 the Chiyoda JGC Joint Venture (CJJV) awarded the contract to design and construct the LNG and condensate offloading jetty for the PNG LNG project to the BAM Clough Joint Venture. The award represents a third contract for Clough on the PNG LNG Project.

The LNG and condensate jetty will be constructed adjacent to the planned LNG facility twenty kilometres northwest of Port Moresby on the coast of the Gulf of Papua, utilising an anticipated workforce of 500 people. The scope includes the design and construction of a 2.4 kilometre long trestle with substation platform, loading platform and single LNG load-out berth.

In October 2010, BAM Clough received an additional Letter of Intent for the fabrication and construction of the topsides for the PNG LNG condensate offloading jetty. The second contract is valued at approximately $53 million, bringing the total value of contracts awarded to BAM Clough for the PNG LNG jetty project to $376 million.

An integrated design team within the project organisation ensures short communication lines and frequent constructability reviews integrated throughout the development of the design.

Project Execution:

The approach-trestle consists of precast concrete headstocks on steel piles with precast concrete T-beams over the concrete headstocks for the roadway.

The pre-cast structural elements are fabricated at BAMs Decorient Precast Yard in Indonesia and transported to site.

The pipe-rack modules (topsides) are fabricated and assembled at Cloughs Sattahip Fabrication Yard in Thailand and transported to site for installation.

BAM Clough has designed and fabricated a Cantilever Bridge (CLB) (see image above left) and its supporting equipment such as a Self Propelled Trailer (see image above right). This CLB will be used for the construction of the approach trestle over a section of water which is not accessible by conventional marine spread thereby leaving a minimal environmental footprint.
