Damen Shiprepair Vlissingen (DSV) has commissioned a shore power facility with increased capacity for dry docks 1 and 2. The shore power ensures that docked vessels can get their power directly from shore, eliminating the need to use generators. This provides major benefits, explains DSV E-Coordinator Marco Proost. “We are now making efficient use of the power available in the yard,” he says. “This solution provides huge savings in terms of CO2 emissions and we can save on the expensive fuel costs for gas or diesel and the maintenance of the generators.”

The new generations of ships demand more electric power, which meant that diesel generators increasingly had to be used. As E-Coordinator, Marco started looking for a cleaner and cheaper alternative a year ago. He could remember working in the past with an inverter truck that could be connected to the pump room when more power was needed. “Basically, we recycled an old idea,” he says.

He put the idea to installer Delmeco, which resulted in a solution. The yard has an existing 10KV cable for the dry dock pumps and a static transformer is now connected to it. 1200A can now be supplied through this transformer instead of the previous 350A. The yard’s fixed dock pumps are normally used only during the dry-docking of a ship. Once a ship is in dock, this electrical power can be used for other applications, such as for the power consumption of a ship.

The first ship that could benefit from the new shore power supply is the patrol vessel HNLMS Friesland. The ship has been at DSV since August and representatives of the Dutch Naval Maintenance and Sustainment Agency were present when the installation was commissioned.
