Current projects


In 2008 SubSea Infrastructure installed a temporary modular desalination plant for Limassol, Cyprus. This plant was delivered in an unprecedented 8-months. This is the first of a generation of high output, low-impact, mobile desalination solutions to be employed around the world.

The plant, located at Moni, produces 21,000m3 of water/per day, providing the perfect interim solution to the serious water shortage problems being experiences on the island.

The mobile plant will operate until the end of 2011. It can then be completely removed, relocated, and pumping water within 3-months, either as a barge or land-based solution. The modular nature of the design would also enable the option of scaling up production as desired.

East Coast USA – Long Term, Scalable, Water Provision

SubSea Infrastructure recently worked on a feasibility study to provide a number of growing conurbations on the East coast of the USA with an offshore water supply solution covering a period of 40-years.

The complexity of the situation was such that the supply profile started very low at 2.8MIGD (10,000m3) rising to 75MIGD (285,000m3) over 40-years.

Additionally, minimisation of environmental impact was critical as was the desire to minimise the loss of prime, green field, beach front, real estate to industrial plants.

The highly flexible and easilly scalable nature of the SubSea Infrastructure offshore solution meant we were able to engineer three alternative senarios that ensured an almost infinitely adaptable approach could be developed.

Importantly the only impact onshore was the need for a narrow corridoor for the water delivery pipeline to the network interconnection. Since this would be buried after installation there would be effectively no significant impact on the beach front environment and no visual pollution whatsoever.

By deploying the desalination plants offshore from floating vessels an added advantage is the ability to disperse the brine discharge more widely. In this regard SubSea Infrastructure has a patented dispersal system. In addition, where the marine environment is ultra sensitive, we are able to demonstrate a brine dilution system prior to ever discharging the brine stream into the sea.

Saudi Arabia – 2 x 26,000m3 SWRO desalination barges

In 2007 SubSea Infrastructure responded to a tender for the provision of two desalination barges, each providing 26,000m3 of water/per day.

This marks the first commercial tender for medium-to-large-scale SWRO desalination from floating units and SubSea Infrastructure submitted a technical and well detailed response.

While SubSea Infrastructure did not secure this tender the barges were built and are currently in service, having been fully employed since 2009.
