Black Point Power Station
Tixobent For Pipe Jacking
in Hong Kong
Located in the New Territories region of Hong Kong, Black Point is one of the world’s largest gas-fired combined-cycle power stations with ultra low-sulphur diesel as backup fuel source. Leighton Asia won the contract to upgrade the power station that has been in operation since 1996. Siam Minerals was brought on board to provide slurry materials, as well as quality control (QC) services and equipment.
The scope of work on the power station included excavation and lateral support activities, as well as developing deep shafts and pipe jacking for the delivery of a new cooling water intake and discharge facility, which includes a new pumping station and underground cooling water pipelines. In addition, a maintenance shaft and turbine hall will be used to house the power generation equipment and associated facilities.
