DESMI Ocean Guard BWTS picked for Maersk newbuilds

NOVEMBER 9, 2015 — Aalborg, Denmark, based DESMI Ocean Guard A/S is to supply 14 RayClean ballast water treatment systems (BWTS) for a series of new container vessels to be built at China’s COSCO Zhoushan shipyard for Maersk Line.

The BWTS 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.

DESMI Ocean Guard notes that the RayClean system was developed in close collaboration with Maersk Line and meets Maersk’s requirements for proven performance under all conditions, low operational cost, and ease of use.

“We are pleased with our cooperation based on which we are comfortable that DESMI Ocean Guard can deliver the right system for this project,” says Maersk Line’s Michael Heimann.

“Total Cost of Ownership analyses have shown us that the RayClean system will provide considerable operational cost savings to Maersk Line compared to competing systems, due to the low power consumption and long lifetime of the UV lamps,” says Rasmus Folsø, CEO of DESMI Ocean Guard. “At the same time, the RayClean system is certified for use in all salinities and down to extremely low UV-Transmission levels not matched by any other system on the market.”

DESMI Ocean Guard says that 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 IMO and U.S. Coast Guard discharge standards.

The company says that another deciding factor for Maersk Line’s selection of the RayClean™ system was that the system 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.
