DESMI Ocean Guard to supply ballast water treatment systems for seven Maersk ships

(AALBORG, Denmark) — DESMI Ocean Guard has announced that the RayClean ballast water treatment system (BWTS) has been selected for installation on a series of new container vessels for Maersk Line. The vessels will be built at COSCO Zhoushan Shipyard Co. Ltd. and the ballast water treatment systems will all be delivered in 2016 and 2017. The order is for seven vessels each equipped with two RayClean 500 BWTS. The order includes options for two additional vessels.

The RayClean system was developed in close collaboration with Maersk Line, and therefore the system meets the requirements of the shipping giant for proven performance under all conditions, low operational cost, and ease of use. Total cost of ownership analyses have shown that the RayClean system will provide considerable operational savings to Maersk Line compared to competing systems, due to the low power consumption and long lifetime of the UV lamps.

At the same time the RayClean system is certified for use in all salinities and down to extremely low UV transmission levels. UV transmission is a measure of how dirty and challenging the water is to treat for a UV-based system. The lower the UV transmission, the more challenging it is to treat the water according to the IMO and U.S. Coast Guard discharge standards.

Another deciding factor for the selection of the RayClean system was that it has completed all the required testing for U.S. Coast Guard type approval, and a full type-approval application was submitted to the USCG earlier this year.

This contract for DESMI Ocean Guard is the latest in a string of contracts, including supply of the RayClean system for the Royal Canadian Navy’s new Arctic offshore patrol ships and retrofit projects on Danish shipowner Nordana existing vessels.
