“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.

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.

“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.
