Tanjung bin submarine pipeline

In 2007, the Murray & Roberts–SYS joint venture was contracted by Kencana Infrastructure Sdn Bhd to install a 900-meter-long, 580mm OD submarine pipeline across the Pulai River to supply water to the Tanjung Bin Power Station. The project, valued at RM 8.3 million, was completed within a six-month contract period from February 2007 to July 2007.

Initially, the pipeline was intended for installation using a horizontal directional drilling (HDD) method. However, due to technical difficulties, the HDD option was abandoned, and the project was completed using an “open-trench” and “bottom-tow” method instead. To address the pipeline’s positive buoyancy, concrete half-shells were attached to form a continuous weight-coat for the bottom-tow installation. 

A wire rope was laid across the river, connecting the pipeline to a 300-ton capacity linear winch on the opposite bank. The pipeline was successfully pulled across the river in a single continuous operation, and the project was completed in June 2007
