Design, supply, install, test, commission, mobilise, demobilise, operate and maintain a dewatering system capable of operating at flows of 1000 l/s and removal of sea water from within the construction zone to allow civil earthworks to be completed at the John Holland laydown facility at Fisherman’s Landing, Gladstone, Queensland for use on the GLNG Materials Offloading Facility on Curtis Island.

Due to the critical nature of the project, the system was under 24 hour surveillance and maintenance by our pump technicians.

The project duration was February to July 2013 (Mob to Demob) and all tasks were completed efficiently and effectively.
