The cooling water intake station project was initiated to provide additional cooling facilities for utilities and plants in Shell Bukom refinery.
With this construction, conveyance of water is possible from a sea inlet into a pump station, and then finally through the myriads of pipes into the cooling structures for new plant facilities.
With a treacherous seabed consisting of six 66 kVA subsea cables, aplenty of risks stands in the way of constructing the submerged offshore intake structure. In anticipation of the dire consequences of hitting the subsea cables, HSL expertise was called upon and careful studies were performed by the project team. Regular meetings and detailed presentation of the execution plan further convinced the relevant stakeholders before the project commencement that works can be executed safely as planned.
Apart from performing surveys to accurately locate the subsea pipelines, divers were deployed before pitching of every pile. Based on HSL past experiences and documentation of potential issues with cooling water intake station, we further recommended compartmentalized inlets to allow periodic maintenance and shutdown of the station.
The project was successfully completed with full compliance to HSL’s safety philosophy of ensuring zero harm to the people involved in the project. With each passing year, cost savings are passed on to Shell as the water intake station continues to provide reliable cooling with minimized shutdown time for maintenance.
