Vacon® NXP Grid Converter Low Voltage Drives Danfoss / Vacon

Cleaner power for ships and ports

The VACON® NXP Grid Converter is an alternative source of marine power technology that plays a key role in reducing fuel intake and improving efficiency. It can be applied to power generation for ship engines and harbor power supplies to meet the demands of governments and port authorities.

When used with a shore-supply solution, VACON NXP Grid Converter allows electrical power to be sourced from the local grid via a set of cables, rather than the ship’s main engine or generators. This process, sometimes known as ‘cold ironing’, has a significantly positive impact on fuel economy. It causes reductions in CO2, NOx and SOx emissions, as well as noise and vibration levels.

VACON NXP Grid Converter can also be applied to shaft-generator solutions, ensuring that propulsion machinery is able to operate at various speeds. The shaft generator decouples shaft RPMs from the electricity (frequency) which allows better electrical quality and improved fuel economy. Additionally, power can either be taken from or entered into the propeller shaft. This is particularly useful for ships that often alternate their speeds as it creates fuel savings and minimizes exhaust emissions by up to 15%. It also creates an emergency mode meaning that the vessel can operate even if the main engine fails.
