This tunnel thruster is the largest and most powerful thruster we have ever produced. It has a propeller diameter of 3,5 meters and is capable of a power output of 5000kW. Twelve units have been sold to three different cruise vessels, and the first units will be delivered in 2027.
Brunvoll has expanded its rim-driven thruster series with the RDT2100, a thruster with a 2,1-meter propeller diameter and a power range of up to 1600 kW. RDT2100 is a result of market demand, and the first units are for a Service Operation Vessel project in the United States.
This is a new size of Brunvoll’s ducted azimuth propulsion unit. It was developed in 2023, and the first installations took place on an offshore wind vessel in the United States in Q1 2025
Perpendicular Twin-In Singel-Out (PTS) means the gearbox takes in power from two electrical motors positioned vertically above the gearbox and has one single shaft out. This solution has a short building length compared to other solutions with the motors in front, which enables alternative arrangements and space savings.
These tunnel thrusters are resiliently well-mounted, which dampens the noise and vibration levels on board the vessel. The first five were delivered and installed in 2024.
Brunvoll has a long tradition of designing and producing retractable azimuth thrusters. These new thrusters are developed with a specialised solution to allow for emergency repair of the thruster unit in situations where dry-docking the vessel is challenging.
The very first Brunvoll BruCon DP2 dynamic positioning system was installed on the offshore support vessel Stril Mar in January 2024. The BruCon DP2 installation was part of a larger power and energy management system upgrade onboard Stril Mar, delivered by SEAM AS. The installation and sea trial was a success, which resulted in an additional order of dynamic positioning systems for two of Simon Møkster Shipping vessels, the Stril Mermaid and the Stril Mariner. The second DP2 system for Simon Møkster was installed on Stril Mariner in December 2024, completing everything from installation to technical testing and sea trials in just 20 days.
The Brunvoll BruCon DP2 system is a modern control system with a human-centred interface design, fully developed in-house. The engineers behind it have delved into the latest research and methods on control theory, with estimation and filtering based on nonlinear passive observers.
BruCon FishPilot – system for efficient fishery
BruCon FishPilot is a solution for fishing vessels that enables less focus on vessel manoeuvring and more on gear and catch. This way, the crew can continue their successful operations with increased autonomy, safety, and efficiency. In short, FishPilot autonomy takes control over the vessel’s course, speed, or track, depending on the operator’s preferences. It allows for steadier vessel operations, enabling energy efficiency through reduced accelerations.
At Brunvoll, we believe that progress is built on continuous innovation. By listening to the market and pushing technological boundaries, we are shaping the next generation of maritime solutions—ensuring efficiency, sustainability, and reliability for years to come.
