South Korea: DSME Orders Watermakers for 4 Drillships from Hatenboer-Water BV

Hatenboer-Water BV has recently secured contracts from Daewoo Shipbuilding & Marine Engineering (DSME) for the supply of Demitec® watermakers for four new drillships.

In Okpo Bay in Korea, Guy Heijnen, Manager, Sales & Water Quality at Hatenboer-Water, signed contracts for the projects H3612, 13, 14 and 15. These relate to drillships for Vantage Energy, Atwood Oceanics and two for Aker Solutions. 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.

High quality product water

The watermakers work on the principle of reverse osmosis (RO) and have a capacity of 50 m3 per day. 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.

DSME

DSME is second largest shipbuilder in the world, and the company is well known for its high quality and advanced technology. DSME also enjoys the reputation as always delivering ships on time, and produces an average of one ship per week. These four orders are a confirmation of the excellent working 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.

Demitec®

DEMITEC® is the trade name van Hatenboer-Water RO type watermakers. These are heavy duty installations specially designed for 24/7 operation in maritime and offshore applications. Worldwide there are more that 200 DEMITEC® RO systems in operation.
