ZHEJIANG, CHINA: Australia-listed construction services provider Leighton Holdings will add one more newbuild pipelayer to support its projects in Asia.
‘The new vessel, Leighton Faulkner, is under construction in Zhejiang, China. When complete, the 76-metre (249-ft) long and 24-metre (79-ft) wide pipelayer will be capable of laying up to 32-inch pipes using a 10-point mooring system. Leighton Faulkner will start its first assignment laying a twin 4,500-metre (14,764-ft), 20-inch wide subsea pipeline in support of the expansion of an aviation fuel facility in Tuen Mun, Hong Kong. The pipelayer is scheduled to install a 24-inch, 13.4-kilometre (8.3-mile) offshore pipeline as part of a project commissioned by the Brunei Economic Development Board. The US$73 million project is due for completion by February 2010 and will also involve the engineering, procurement, installation and commissioning of an associated pipeline end manifold and a single point mooring (SPM) system. The pipeline system is designed to handle a flow of up to 1,600 tonnes (1,760 tons) an hour of methanol. The SPM will be a catenary anchor leg mooring type turret buoy with a capacity to accommodate 46,000 dead weight tonne tankers. It will be located in waters approximately 25 metres (82 ft) deep. The project will be supported by a 2,400-hp anchor handling tug, a 2,000-hp tug, two 55-metre (180-ft) supply barges and a crew boat.
