Submersible and special engines from Marotechniek

With more than 30 years of experience in underwater drives, controls and special solutions for the Dredging, Marine, Offshore and Industrial sectors, Marotechniek is your reliable partner. We supply components and complete installations, including controls, software and automation, also as turn-key solutions.

At Marotechniek, we have our own production, assembly and repair facilities, and our service and repair department is available to you 24/7 for on-site inspection and repair. Our engineering department develops and designs all submersible motors in SolidWorks 3D CAD software, and this is done to high quality standards and standards in accordance with IEC 60034 (LV).

Upon request, we can supply our products under a witness load test or full certification by a notified body (NoBo), such as DNV/GL, B.V. or LR.

In 2014, Marotechniek developed an innovative new electric underwater motor based on Permanent Magnet Technology. This motor features built-in “Permanent Magnets,” eliminating the need to magnetize the rotor. The elimination of reactive current reduces the required amperage, leading to higher efficiency. Overall, this motor is 4-6% more efficient than the traditional short-circuit anchor motor and is much more compact and lighter in weight. As of 2015, approximately 30 units are now in successful operation.

Below is an overview of the product range of Marotechniek’s underwater and specialty motors.
