Dampier Bulk Liquids Berth

The Dampier Bulk Liquids Berth opened in 2005 and was constructed to promote and support the downstream gas processing industry on the Burrup Peninsula in the Northwest of Western Australia. 

The marine facility consists of a 500m long jetty comprising 15 spans of 32m and a 20m long access bridge connecting the approach trestle to the 37m x 34m loading platform. The platform was constructed using precast concrete pile caps and beams, with an insitu concrete deck.  It currently supports two loading arms (diesel and ammonia) but has the capacity to accommodate up to seven loading arms in total.  The four berthing and mooring dolphins allow for vessels up to 65,000 DWT to berth alongside for loading and unloading.

Maintenance has generally been carried out on a cyclical basis with replacement of components as required but, as part of a broader asset management strategy, the Pilbara Ports Authority requires a detailed asset inspection and management plan to determine appropriate maintenance strategies for the future.

The Pilbara Ports Authority engaged Pritchard Francis to undertake such an inspection in accordance with the Ports Australia Wharf Structures Condition Assessment Manual.  From the information gathered on site, a 10 year asset management plan and budget estimate were created.  Liaison with sub consultants specialising in corrosion mitigation and marine construction was also undertaken throughout the project.
