This ship carries out surveys of the sea bed. Their main task is inspecting underseas cables and pipelines. It has a huge amount of underwater sensing equipment, systems, and computers.

The diesel generator runs continually to supply power to the survey equipment and the powerful computers. But the main engines run all day as well. So the idea is to provide the 230v board net with an inverter supplied by a battery bank. This is charged by the 24v DC from both main engines alternators. With this, the diesel generator would no longer be necessary, saving emissions and costs….

We install a Victron Quattro charger/inverter with a power of 8kVA, supplied by 4x 220Ah GEL batteries. These are charged by the alternators on the main engines. 8 kVA is sufficient for all survey systems, computers, and domestic equipment.

We refit the entire primary DC distribution.

New cables are run to the ship’s AC system…

…And a new AC distribution cabinet is installed.

The Victron Cerbo monitors and controls the entire system.

The result: 2 months later, during a visit on board, the skipper tells us he doesn’t use the diesel generator at all! Previously, the genset ran 24/7!!!

We implemented this project in close collaboration with employers and suppliers:
