CATC is all about reducing power consumption onboard ships.
We believe that, with our extensive experience in marine automation we can lower the power consumption onboard any vessel without sacrificing passenger and crew comfort.
All above contributing to a cut in fuel costs and reduced emissions.


A constantly ongoing development is the key to the success of any technology-oriented company. A tight relation to our customers is helping us to identify new saving potential in various areas onboard. Our core competence lies within HVAC controls but any automation intensive system is subject to our interest. Examples of projects finalized: HVAC control system, engine room ventilation control, SW/LT pump control, fuel and power monitoring, BNWAS system, SCR controls…. (The list is growing.) Our solutions apply to new builds and retrofits.


We have chosen the name “ViewPort” for our control system solution. We strongly believe that a system with high complexity needs a simple interface to be used onboard a ship. Today’s ship management requires more and more crew rotation and each individual handling the system must be able to quickly grasp and use the system without additional training. We believe that ViewPort fulfill these requirements. Products used in our projects are mainly of marine type, long life cycle and well proven in the marine environment.
