Kongsberg Maritime has launched a new rim-drive azimuth thruster, the RD-AZ-2300, designed to fill a perceived gap in the market and offer a powerful and efficient propulsor for a wider variety of vessels.
The RD-AZ-2300, with a propeller diameter of 2300mm, sits between the existing RD-AZ-1900 and RD-AZ-2600 models, providing ship owners and operators with additional flexibility in selecting the right thruster for specific applications. The RD-AZ-2300 is suited for vessels operating in demanding environments such as offshore wind farms, where precise manoeuvrability and low noise levels are essential. In adherence to DNV’s Silent R classification, the RD-AZ-2300 provides advantages to underwater research vessels by reducing underwater radiated noise (URN) below sea levels, which is beneficial to marine ecosystems and enhances onboard comfort for crew and passengers.
The thruster’s robust design and high torque output make it suitable for the demanding conditions often encountered in these operations, helping to minimise environmental impact, above and below sea level.
Anton Westerlund, Kongsberg Maritime VP Product Management, Thruster Systems said: “We are excited to introduce the RD-AZ-2300 to the market. This new thruster size further strengthens our position as a leading provider of electric propulsion solutions. The RD-AZ series offers exceptional performance, efficiency, and manoeuvrability, making it an ideal choice for a wide range of vessel types.”
Kongsberg Maritime has a long history of electric propulsion technology. The company’s rim-drive azimuth thrusters are known for compact design, high efficiency, and low environmental impact. By eliminating the need for gearboxes and traditional shaft lines, the thrusters reduce noise and vibration, while improving fuel consumption and reducing emissions.
