Ship mounted reverse osmosis plant to supply water to Australian LNG plant

Adelaide-based Osmoflo will build two ship-mounted plants to potable and process water to crew working on LNG and hydrocarbons from Ichthys field in the Timor Sea.

Following a global tendering process, South Korea's Daewoo Shipbuilding Marine Engineers and Samsung Heavy Industries selected Osmoflo for this project.

The two ships are currently under construction in South Korean yards. One vessel will carry a single pass reverse osmosis plant consisting of two 100 kilolitre per day (KL/d) trains which will process seawater to potable standard.

Additional treatment including remineralisation, ultra violet (UV) sterilisation will provide high purity process water which will be used to clean generator turbine blades.

On the second ship, Osmoflo will build a two pass reverse osmosis system in two 150kL/d trains to process seawater for potable requirements.

Both reverse osmosis plants are being built at Osmoflo’s main facility in Burton, South Australia. The units will be designed to meet oil and gas industry, marine and environmental requirements. They will be fitted and commissioned before the vessels leave the shipyards.

The ships will be permanently moored at a location some 440 km north of Broome and 800 km from Darwin. The first will partially process recovered gas to remove water, raw liquids and condensate prior its transportation by pipeline to an on-shore processing facility at Blaydon Point, Darwin.

Currently under construction at a cost in excess of $40b the Ichthys project includes the development of Timor Sea wells, a connecting pipeline to Darwin and the construction of a large processing facility.

Lead developer is the Japanese company INPEX. The Darwin facility will initially produce 8.4 million tonnes of LNG per annum and 1.6 million tonnes of liquefied petroleum gas as well as approximately 100,000 barrels of condensate per day at peak.

Last year Osmoflo was awarded a contract for a membrane based demineralisation plant which will provide 1,565kL/d of high purity water to a new power station that will provide electricity to the Darwin processing facility.

These latest contracts consolidate Osmoflo’s position as a preferred supplier to the LNG industry. All three massive LNG projects currently under development off the north-west coast of Australia, Gorgon, Wheatstone and now Ichthys have placed multiple orders with Osmoflo for desalination systems.

“The oil and gas sector demands a rapid response and high compliance with industry standards from its service companies along with the capability and competitiveness to participate in global tendering. Osmoflo is structured to enable us to provide world’s best practice at the right price, factors that account for our continuing success in this industry sector,” said Marc Fabig, Osmoflo Managing Director.
