Fishing vessels




DEIF offers a complete range of devices that help you design, build, install, and operate power and energy control solutions for anything from small single-engine boats to large factory ships with extensive processing equipment.

We help you control any energy source plus the necessary breakers, inverters, converters, and power distribution. Our PMS and EMS (power and energy management systems) work with all power and energy sources, from diesel engines to fuel cells, and you can use them with AC and DC architectures – or a combination of both.

Need a power boost to haul in the catch? Need to save fuel and reduce emissions? Need to get home after an engine failure? With DEIF, you can help crews handle all this and more, and work towards a future of climate-conscious fishing. In short, you can build anything your fishing industry customers need.



Check out the application examples below to see some of the possibilities you get with DEIF expertise and devices.




Full range of devices

Networked controllers like the iE Marine series , PPM 300 , and AGC 150 Generator Marine ensure continuous control of all energy sources. Compact and efficient iE Convert power converters handle all energy conversion tasks. And our complete range of bridge instruments , graphical interfaces , switchboard equipment , and accessories give crews the full control they require – from each individual controller, from the engine room switchboard, and from the bridge. Compatible with a wide range of devices, DEIF devices can be integrated on existing vessels or form the backbone of your newbuilds.





Emission reduction ready

DEIF devices support emission-reduction technologies that cut fuel consumption and optimise energy utilisation. Examples includes integrating batteries, fuel cells, and shore connections in hybrid power solutions, and controlling waste heat recovery systems that reduce power generation requirements.

Custom engineering available

Our devices support all standard operating scenarios and are very flexible and scalable. If you nevertheless find that our off-the-shelf devices do not deliver the features or performance your customers need, we can engineer a bespoke solution that does.

Knowledgeable global support

DEIF has been in business since 1933, and we have decades of experience in maritime power and energy control. When you work with us, you get knowledgeable support round the world based on that extensive experience, and we supply the documentation and training you need to make the most of your devices.



Custom DEIF devices combine AC and DC busbars in hybrid solution for fishing

A custom engineered DEIF control system is handling energy management on two Norwegian fishing vessels energised by an innovative hybrid solution with AC and DC busbars. DEIF solutions and support are helping the shipyard and electrical installation company introduce innovative ideas and solutions that contribute to the energy transition at sea. “We can give them nothing but our warmest recommendations,” says the co-owner of the installation company.
