At 204.7m long, the JSS will be the largest vessel in the Navy’s fleet. The JSS is 28m longer and 10,000 tonnes heavier than HMS Johan de Witt, which was built in 2007. The JSS will be used for replenishment at sea, sea transport and sea basing and provides facilities for replenishment, storage, transport, loading and unloading, provisions for medical, technical and logistical support, and accommodation for the crew (maximum 300 persons) and evacuees. The ship is to take to the seas in 2014.
The ballast water capacity of the installation for the JSS is 1,400m3 per hour and Hatenboer-Water decided to place two identical 700 m3/hr installations in parallel, one on the port side and one on the starboard side. The systems can function completely independently from one another, securing a backup capability, but they can also be linked. Hatenboer-Water has also supplied installations that can treat 150 to 1,000m³/hr of ballast water, and by installing parallel systems it is therefore now possible to treat as much as 6,000m³/hr.
The GloEn-Patrol system uses filtration to remove suspended particulates and UV-C radiation to destroy organisms and microorganisms. The system is fully IMO certified.
In addition to the ballast water treatment, Hatenboer-Water is also covering the ship’s drinking water supply, including complete drinking water production, distribution and after-treatment to ensure the quality of the water.
