Copenhagen Subsea is a leading developer of electric underwater thrusters for subsea robotics systems such as offshore ROVs (remotely operated vehicles) and AUVs (autonomous underwater vehicles), as well as USVs (unmanned surface vessels). We can provide customized subsea propulsion solutions to meet your unique application requirements.
We have also developed the Gorilla ROV, which combines our leading submersible thruster technology with high-reliability industrial electronics, to deliver a robust ROV for underwater inspections in challenging offshore environments.
Electric Underwater Thrusters
Submersible thrusters for ROVs, USVs, AUVs
Our powerful and silent underwater electric thrusters feature an unprecedented power-to-size ratio, delivering a fast response time and excellent maneuverability making them ideal for ROVs, USVs and AUVs.
With only one moving part, the thrusters exhibit a low acoustic signature and are ultra-reliable, with a thousand hours of in-water endurance tests.
We can provide thruster solutions with a combination of different propellers, as well as inlet and outlet rings that can be configured in two different setups:
- Asymmetric configurations are optimized for high and efficient thrust in a primary direction – ideal for main propulsion in vehicles that have a forward direction
- Symmetric configurations are optimized to deliver the same amount of thrust in both directions – ideal for station-keeping ROVs
Our electric submersible thrusters have been equipped worldwide on a variety of subsea and surface robotic platforms, including Embry-Riddle University’s WAM-V 16 Autonomous Surface Vessel (ASV) entry for the RobotX unmanned systems competition.

Gorilla Remotely Operated Vehicle
The Gorilla ROV is an offshore ROV designed to undertake challenging missions in harsh underwater environments. Featuring eight of our powerful, electric underwater thrusters, the system is equipped with an intelligent Dynamic Positioning system that provides automatic control of position, depth, altitude, heading, pitch and roll.
The electronic subsystems of the Gorilla ROV are based around highly reliable industrial-grade components from OMRON, built to handle extreme working conditions including high current inrush and current overload from the thrusters. The open platform and widely available spare parts allow users to easily maintain the system themselves.

Maneuvering Subsea System
Precise heading & positioning control for subsea tools & equipment
Our Maneuvering Subsea System is a complete electric propulsion solution that incorporates a control panel, control cabinet, motorized cable winch, and our innovative subsea thrusters. Industrial-grade hardware provides an excellent level of reliability and maneuverability, resulting in precise positioning of subsea tools with extremely fast response times.
The versatile system can be adapted to a wide range of subsea equipment, tasks and applications, such as cable and pipe detection, seabed installation, and inspection and repair.

AUV Propulsion Solution
Powerful propulsion for subsea robotic vehicles
Our AUV propulsion solution is based around our highly reliable electric thruster technology and features a specially-designed 3D-printed composite bracket that attaches the thruster to the AUV and also acts as an inlet nozzle.
The seawater-cooled AUV thrusters can be customised to fit specific electrical requirements, and are equipped with an angled penetrator for easy mounting. Brackets are available to fit all of our thrusters sizes, from VS to VXL.
