Ulstein Verft has contracted Norwegian Greentech to deliver the ballast water treatment systems (BWTS) to two Commissioning Service Operation Vessels (CSOVs) that the Norwegian shipyard is constructing for Bernhard Schulte Offshore.  

“We have delivered multiple BWTS systems to Ulstein Verft over the years and are therefore highly familiar with their stringent quality requirements. We are proud to be chosen for these two newbuilds,” says Lars-Tore Lynge, Sales Manager at Norwegian Greentech. 

FOR THE OFFSHORE WIND INDUSTRY 
The two vessels – NB320 and NB321 – are both CSOVs for the offshore wind industry. The vessels are of the ULSTEIN SX222 design. The ships will have hybrid battery propulsion and be prepared for methanol fuel to enable carbon-neutral operations. 

Norwegian Greentech will supply its energy efficient ballast water treatment system to the two newbuilds. The company has developed a method that combine UV and filters. The chemical-free system has a highly compact design, which is ideal for difficult-to-fit engine or pump rooms.

TAKE GREAT PRIDE 
“We take great pride in our technology and the significant environmental and operational benefits it offers to shipowners. Hence, we consider our system to be a good match for the extensive fuel efficiency features that these CSOVs will be equipped with,” says Børge Gjelseth, SVP Commercial at Norwegian Greentech. 

Norwegian Greentech will manufacture the ballast water treatment systems at its headquarters in Fosnavåg, Norway, and deliver them to Ulstein Verft. The company has not disclosed the value of the contract.
