Hatenboer-Water has secured contracts from Daewoo Shipbuilding & Marine Engineering (DSME) for the supply of Demitech reverse osmose installations for four new drillships.

In Okpo Bay in Korea director Hyun-Kyoo Choi, Offshore Procurement at DSME and sales manager Guy Heijnen at Hatenboer-Water, signed contracts for the delivery of the four on board water supply installations for the ships that will be delivered to Vantage Energy, Atwood Oceanics and two for Aker Solutions.

Director offshore procurement Hyun-Kyoo Choi of DSME hands over the contract to Guy Heijnen of Hatenboer-Water.

The drillships are the newest generation of ultra deep drilling ships, which can drill to a water depth of 12,000 ft (3 km). The ships are currently under construction, and the delivery of the watermakers is planned for this year.

Maritime and offshore applications
The Demitec RO system is a heavy duty installation specially designed for 24/7 operation in maritime and offshore applications. Worldwide there are more that 200 Demitec systems in operation. They work on the principle of reverse osmosis (RO) and have a capacity of 50 m3 per day.

Salt content below 10 ppm TDS
Drilling at great depths demands an extremely high quality of product water. The installations can supply water with a purity of only 10 ppm TDS. To obtain such a standard, the installation is in a two-stage configuration, with two RO installations in-line. The first unit desalinates to 500 ppm TDS and the second delivers product water with a salt content no higher than 10 ppm TDS.

World's second largest shipbuilder
DSME is second largest shipbuilder in the world. The four new orders confirm of the good relationship between Hatenboer-Water and DSME. In 2011, installations were delivered for drillships for Transocean, Petroserv, Odebrecht and TMT, among others. Hatenboer-Water also received orders in 2011 from DSME for Heerema’s Aegir and the Pieter Schelte, which was built for Allseas.
