Selection Guide l VACON® NXP Grid Converter r Reduce emissions and noise in ports and on ships with grid converter technology 10% fuel costs savings on shaft generator with VACON® NXP Grid Converter technology at M/V Bore Sea.

Reduce emissions and improve efficiency The limits of the worlds natural resources dominate our times, and the marine industry is taking on the same challenges as everybody else regarding energy usage. VACON® NXP Grid Converter technology helps ship owners and port authorities reduce fuel intake and improve efficiency. This will please investors and environmental legislators alike – after all, lower energy consumption equals lower costs. Ships require power when at sea and when docked in the harbour. Power is not only required to propel ships around the world, it also provides electricity to...

Shore supply solution with VACON® NXP Grid Converter Ships travel from port to port, sometimes stopping in a new country each day. Ports don’t all use the same electrical frequencies, and ships have historically used a fuel-driven onboard generator to provide electrical power while docked. This is costly though, and city councils and local residents are reluctant to tolerate the noise and poor air quality that is often associated with a busy city harbour. Many port authorities now prohibit, or at least strictly limit, the use of diesel generators while ships are docked. VACON® NXP Grid...

Case studies Clean power for the largest port in the world The port of Shanghai Location: Shanghai, China The Port of Shanghai is the busiest in the world in terms of cargo throughput, with nearly 170 large ships docking each day. Annual trade accounts for around ¼ of China’s total foreign trade. This activity inevitably puts a strain on the local environment, which is why the port uses a movable 2000 kVA shore supply system to supply electricity from the national grid to ships that are docked. VACON® NXP Grid Converter technology plays a key role in this design, ensuring 10 kV of shore...

Shaft generator solution with VACON® NXP Grid Converter The cruise liners and cargo ships of today tend to resemble mobile cities with vast infrastructures. They require a huge amount of electricity to maintain both their internal setup and the mechanical power that’s needed to travel around the world. Due to constant voltage and frequency requirements of the ship’s electrical network, the main engine operates at a fixed speed. For a number of years now, shaft generators have been used to supplement this with variable amounts of electrical power. With VACON® NXP Grid Converter technology,...

Case studies RoFlex® vessel with energy efficient shaft generator configuration WE Tech / M/V Bore Sea Location: Helsinki, Finland M/V Bore Sea was one of two RoFlex vessels ordered by Rorel Ltd to transport Airbus components. After the enforcement of the SEEMP in January 2013, WE Tech Solutions Oy developed a solution which optimized main propulsion machinery and improved energy efficiency. They chose a solution based on VACON® NXP Grid Converter technology. This is a system combining the shaft generator and the ship’s electrical network which allows for large variation to the main...
