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.

Smart grid converter

VACON NXP Grid Converter for smart grids improves stability in the grid by supporting a diverse range of energy generators and energy storage systems. By enabling peak shaving, it in turn reduces the capital investment required for grid infrastructure. It is certified for grid code compliance in a wide range of countries, for fast system certification for system integrators.

Shore supply power conversion

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.

Support for system integrators

Danfoss supports system integrators (SI) in designing their systems to bid on projects. Our aim is to help customers by providing tools and reference designs to make their system design easier. For instance, Danfoss can provide configurable 3D models as well as 2D general arrangement drawings from our product offering.
