Maritime background, our experience and expertise allow us to be a reliable partner to shipowners, shipyards and designers and this is the cornerstone to our business.
Propulsion & Manoeuvring Systems

Innovative Solutions for Efficient Manoeuvring and Propulsion.
Your trusted partner related to propeller propulsion and manoeuvring solutions: from consultation and design to manufacturing, commissioning, maintenance, and repair, we offer a comprehensive range of services with the high-profile manufactor Brunvoll.
Waterjet Propulsion

Waterjets without compromise
HamiltonJet are a single focus manufacturer specialising in the design and manufacture of waterjets and controls.
Waterjets are used when high speed, high acceleration, agile maneuverability or use in shallow water is required.
The HamiltonJet waterjet offers many advantages over competing marine propulsion systems and is particularly suited to high-speed planing vessels operating in the 20 -50+ knot range.
Vacuum Sanitary Systems

The Vacuum and sanitary system for any vessel
By combining Jets® Vacuum and Poloplast we can offer a package whose elements match perfectly.
- Jets® Vacuum and Sanitary Systems
- Poloplast pipes for vacuum application
Flexible and durably sanitary solutions
The simple in-line installation of the Vacuumarator® pump, a small footprint and low weight make Jets® the preferred solution for vessels – from one-toilet cabin systems to the world’s largest cruise vessels.
Three Layers for Eternity
The three-layer, reinforced polypropylene (PP) vacuum piping system is suitable for both black and grey water applications. Its properties make poloplast superior in noise and scaling reduction.
Ballast Water Management Systems

Ballast Water Management Systems made by Norwegian Greentech – One of the most compact and most efficient systems in the market today.
An important part of this system is the ultraviolet chamber, ensuring high performance with the lowest energy consumption when compared to competitors. This is achieved thanks to smart light control based on water transmittance and flow needs.
Norwegian Greentech BWMS is certified in accordance with IMO and USCG.
