Flexible open-source programmable DEIF solution helps Croatian ship designer win order
Flow Ship Design used CODESYS-based DEIF controllers and user-friendly operator screens to develop a simple but efficient complete control solution that helped the company win a strategically important order for a new fish farm inspection vessel.
“The modularity of the system, the flexibility, the programmable development platform – for us, these are the strong points,” says Ivan Vidić, Senior Electrical Project Engineer at Flow Ship Design. The company recently won an order with Norwegian shipyard Moen Marin, the world’s largest supplier of working boats to the aquaculture industry.
The order calls for a complete control system for a new fish farm inspection vessel, and the Flow Ship Design solution is based on DEIF components. While Flow Ship Design was already familiar with DEIF power management solutions, it is the first time that they have used DEIF components for a complete control solution on board – but it may not be the last.
Fast delivery with DEIF
For the order with Moen Marin, Flow Ship Design chose to carry out all design and construction work themselves instead of working with external suppliers, but the company soon ran into delivery issues: The controller suppliers they usually work with could not deliver on time. Looking for a partner that was capable of better logistics performance, Flow Ship Design contacted DEIF.
“To be honest, we originally only considered DEIF for the power management system, but we had big issues with our usual suppliers regarding delivery dates,” explains Ivan Vidić. “So far, DEIF have given us really good delivery dates. With other suppliers, CPUs have been delayed for a year which makes it impossible to make projects; you can’t tell your customer, ‘In two years, I’ll complete your project’.”
Accordingly, DEIF delivered PPM 300 power management controllers for the vessel’s genset and shore connection, both mounted in four-slot racks, plus an AMC 300 controller for the control system. The AMC 300 was mounted in a seven-slot rack with two extension racks to accommodate more I/O modules. In addition, the order included AGI 400 graphical interfaces.
Endlessly flexible and marine approved
Delivery was a very important parameter for Flow Ship Design, but it was not the only deciding factor. While the company had used DEIF power management systems before, Ivan Vidić and his colleagues were unaware that DEIF offers an advanced controller that can be customised to almost any marine control requirement using CODESYS: the AMC 300.
“One of the strong points of the DEIF controller is that it is completely based on CODESYS which is open for programming,” says Ivan Vidić. “We are a small company, and CODESYS allows us to do all the software without investing in expensive licenses and development environments. With CODESYS, you get a basic system which means that I can start from scratch. Also, the marine approvals of the complete equipment are really easy to work with. You don’t need to see what’s approved and what isn’t – everything is pre-approved from the factory.”
The modular design of the PPM 300 and AMC 300 makes them very flexible. Modules can be added or removed for both controllers as required, and they can even be interchanged between the controllers because they are all based on DEIF’s tried and tested Multiline 300 hardware platform.

A strategically important job
The project with Moen Marin is an important step for Flow Ship Design. Ivan Vidić explains the strategic importance of the order. “If it goes well, which I hope it does, we will open up a completely new market and significantly expand our offering,” he says. “We hope that this project is going to mean repeat business for us.”
In addition to reliable, flexible, and modular products, DEIF provided complete freedom with the CODESYS-based solution and fast delivery. The Flow Ship Design engineers are satisfied with DEIF’s general performance on the project.
“We selected DEIF because it’s a proven manufacturer,” concludes Ivan Vidić. “We were convinced from 10 years of using PMS systems from DEIF. And we can rely on the equipment so we can offer it to our customers without any issues. I hope we can cooperate again on our next projects.”
The modularity of the system, the flexibility, and the open-source development platform are the strong points
