To achieve maximum efficiency all aspects must be considered. The single most important parameter is to understand how the equipment is going to be used, what is the operational profile and what is the intended purpose of the vessel. At Berg Propulsion, we work closely with each customer to make sure we understand the full picture before we start to find the best solutions.
This insight allows us to configure azimuth thrusters that are precisely matched to real-world conditions, ensuring optimal performance, reduced energy consumption, and long-term value. The equipment is designed for maximum efficiency considering drive line torque, propeller diameter, hydrodynamic efficiency as well as mechanical efficiency.
Selecting the right thruster size can significantly impact lifecycle costs.
In many cases, choosing a slightly larger unit enables:
This strategic choice can reduce operating expenses enough to offset the initial investment, delivering superior total cost of ownership.
Our continuous product development has led to significantly increased propeller shaft torque within the same thruster size.
What this means for you:
The result is a more powerful and efficient propulsion system.
Berg Propulsion azimuth thrusters are designed using advanced CFD simulations combined with decades of engineering experience. In the design iterations, the azimuth thruster body including propeller and nozzle and the integration thereof are all considered. The interface between the thruster unit and the nozzle are selected with great care. All calculations are made including a typical vessel hull to get a realistic flow condition.
Mechanical losses directly impact fuel consumption and operational costs. That’s why Berg Propulsion azimuth thrusters are engineered to minimize internal losses.
Key features include:
This highly efficient design reduces heat generation to such an extent that, in most configurations, no external cooling system is required. A clear proof of minimal energy loss.
By combining optimized design with application-specific configuration, Berg Propulsion azimuth thrusters deliver:
For electric and hybrid vessels, higher efficiency also means reduced battery capacity requirements, unlocking further cost and weight savings.
Whether
for new vessels or upgrades, the same principles apply: maximize efficiency,
minimize losses, and tailor the solution to your operation.
