Rim Drive Technology has reached an important milestone: the POD series has received DNV Type Approval. This
A subsea bow thruster tunnel set is a complete tunnel solution for safely installing a bow thruster in a submarine, ROV, or other subsea system. The tunnel protects the motor and ensures stable integration into the hull. The subsea bow thruster tunnel from Rim Drive Technology is designed for demanding underwater environments where reliability, protection, and control are essential.
Thanks to the strong stainless steel construction, the bow thruster remains well protected, even under harsh conditions. The various mounting options make installation flexible and suitable for diverse ship designs. In combination with our electric rim drive motors, you benefit from quiet operation, direct response, and minimal maintenance requirements.
Due to the compact design, the bow thruster can be efficiently positioned in the nose of the submarine, ROV, or subsea system. This saves space and supports precise maneuverability underwater. When additional control is required at the rear, the same technology can also be applied as a stern thruster. This makes the tunnel kit flexibly deployable for both bow and stern positioning, depending on the design and desired control.

Within this category, the Bow Thruster 11.0-S, 15.0-S, 25.0-S, and 30.0-S tunnel sets are among the best-selling models. These subsea bow thruster tunnel sets combine powerful performance with a protected tunnel construction. This allows you to easily select a solution that matches your application, power requirements, and preferred installation.
The 11.0-S tunnel set is suitable for compact subsea systems where control and efficiency are important. The tunnel protects the bow thruster and makes hull integration straightforward. This model offers a strong balance between power, reliability, and ease of installation.
The 15.0-S tunnel set provides additional power for heavier underwater applications. Thanks to the strong tunnel construction, the bow thruster remains protected during prolonged underwater use. This makes this version suitable for submarines, ROVs, and professional subsea projects.
The 25.0-S tunnel set is developed for applications where high performance and protection come together. This subsea bow thruster tunnel set provides powerful support and is suitable for larger systems. The different mounting options make integration simple and flexible.
The 30.0-S tunnel set is suitable for demanding installations with higher power requirements. This version delivers reliable performance under harsh conditions and keeps the motor safely protected. Ideal for professional underwater projects where continuous power is important.
Whether you are working on a compact submarine, ROV, or professional subsea vehicle, Rim Drive Technology offers a suitable subsea bow thruster tunnel set. Thanks to the different power classes and mounting options, the solution can be tailored to your design and application.
