Norwegian Greentech is an industry pioneer in small footprint BWTS who understood early the ship owners` demanding requirements in the field.

Direct access to one of the world`s strongest and most innovative maritime clusters – the Norwegian Maritime Cluster, enabled us to create a BWMS unlike any other. Extensive water treatment knowledge, in-depth research and strong partnerships resulted into a smart, cost-effective and scalable BWM solution.

Our state-of-the-art system combines, for the first time in the industry, the smallest footprint with low power consumption, installation flexibility and intuitive operation. Unique system features along with automatic control of the UV dose ensure superior energy performance, low life-cycle costs and easy maintenance. Requiring minimal space, our chemical-free system is ideally designed for difficult to fit engine or pump rooms. The high-quality BWMS of Norwegian Greentech is built to last. 

Over the past decade, Norwegian Greentech has equipped many vessels with well-proven, effective and reliable BWMS (see our Reference List). 


We are on a constant quest to improve the performance of our systems. This motivates us, and we strive to become a leading supplier of compact and highly energy-efficient BWMS. With the driving force of solution innovation, Norwegian Greentech helps ship owners and vessel operators fight the spread of invasive aquatic species. 

Norwegian Greentech is a lean organization that brings value to its customers. This is reflected in our commitment and dedication to help our customers achieve compliance and efficiency in BWT operation by solving their most complex challenges with regards to space and limited power resources available. We define the challenges our customers face, offer competent advice and find an efficient solution that responds their true needs. 

Customer satisfaction is the highest priority at Norwegian Greentech. Easy contact, open dialogue and focused results constitute a solid foundation for the close ties we build with our customers. Besides delivering an approved system, our project execution capacity and service offerings makes us one of the most qualified and trustworthy BWT partner providing customers with a complete scope – from the first contact throughout the vessel`s life.

With strong backgrounds in the maritime industry, both offshore and onshore, our pool of skilled water treatment specialists have over 20 years of industry-defining expertise.
