Goltens wins contracts to retrofit ten Royal Netherlands Naval vessels with Optimarin Ballast Water Treatment systems


For immediate release  

May 26, 2016 

Goltens Worldwide announces that the Defence Material Organization has awarded three contracts to its Green Technologies business unit for the engineering and turnkey installation of sixteen Optimarin Ballast Systems (OBS) on ten Naval vessels.


On May 25 an official signing ceremony was held at the Defence Material Organization in The Hague whereby Captain RNLN J. F. Kwak, Head Projects Procurement Division, officially signed the contract on behalf of the Ministry of Defence. Mr. M. C. Jeronimus, Vice President of Goltens Europe, signed on behalf of Goltens Green Technologies.

Goltens Green Technologies will engineer and install the UV based Ballast Water Treatment Systems (BWTS) onboard the Royal Netherlands Navy vessels during 2016 and 2017, ensuring compliance with both the pending IMO and existing US Coast Guard regulations on ballast water treatment.

Optimarin’s DNV-GL type approved system is fully compliant with the IMO Ballast Water Management Convention, which is currently just shy of the 35% of global tonnage it requires for ratification, and holds an AMS certificate from the USCG. In addition, it is now in the final stages of full USCG approval, having satisfied all marine water tests, with certification expected in the second half of 2016. This will ensure that Goltens provides The Royal Netherlands Navy with a BWTS that is fully compliant for all future operations.

Landing Platform Dock (LPD) vessels HNLMS Rotterdam and HNLMS Johan de Witt, the frigates HNLMS Tromp, HNLMS Evertsen, HNLMS De Zeven Provinciën and HNLMS De Ruyter, as well as special purpose vessels MOV Van Kinsbergen, HNLMS Pelikaan, HNLMS Luymes and HNLMS Snellius will all be fitted with ballast treatment systems during their scheduled maintenance periods.

Goltens Green Technologies, based in Groningen, the Netherlands, is a highly skilled and experienced global force with resources stationed all around the world. Goltens Green Technologies delivers turnkey solutions to address a wide array of environmental compliance challenges by using the latest laser scanning and design methods and technological expertise.
