Product catalog summary
Introduction
The document explores the application of VACON® NXP Grid Converter technology to minimize emissions and noise in maritime environments. This technology aids ship owners and port authorities in reducing fuel consumption and enhancing efficiency, aligning with environmental regulations and lowering operational costs.
Specifications and Benefits
The VACON® NXP Grid Converter enables ships to draw energy from local grids while docked, eliminating the need for fuel-driven onboard generators. This leads to decreased CO2 and NOx emissions, noise pollution, and fuel consumption. Additionally, it facilitates planned engine maintenance and prolongs the main engine's lifespan.
Government Regulations
The International Maritime Organization (IMO) has set forth the Energy Efficiency Design Index (EEDI) and the Ship Energy Efficiency Management Plan (SEEMP) to enhance carbon efficiency and energy management on ships.
Shore Supply Solution
This solution involves connecting ships to local grids using VACON® NXP Grid Converter technology, synchronizing the ship's frequency with the local grid. This allows the main engine to be turned off, reducing emissions and noise while enabling maintenance.
Case Studies
  • Port of Shanghai: Uses a 2000 kVA shore supply system to deliver clean power, significantly cutting harmful emissions and coal consumption.
  • STX Europe: Adopted a grid converter solution to meet EU directives, resulting in reduced emissions and noise at their Turku shipyard.
Shaft Generator Solution
This solution optimizes engine speed while maintaining constant voltage and frequency, enhancing efficiency and allowing flexible speed control, particularly beneficial for ships needing frequent speed adjustments.
Additional Case Studies
  • WE Tech / M/V Bore Sea: Achieved around 10% fuel cost savings and significant CO2 emission reductions using VACON® NXP Grid Converter technology.
  • Viking River: Implemented a shaft generator network to lower fuel consumption and emissions, improving maneuverability and passenger experience.
Technical Specifications
The document provides detailed technical specifications for various product codes, including AC current, DC power, power loss, dimensions, and weight, essential for selecting the appropriate grid converter for specific applications.
Specifications
Details are provided for NX Liquid-Cooled frequency converters with an enclosure class of IP00, emphasizing drive dimensioning for low frequencies, especially below 5 Hz, recommending a maximum current of 0.66*ITH or selecting a drive according to IH. Overrating may be necessary for processes requiring high starting torque.
Product Ratings and Dimensions
Detailed ratings and dimensions for various VACON® NXP Grid Converters are provided, specifying DC power, size, protection, dimensions, and weight for different voltage ranges (465-800 V DC, 640-1100 V DC, and 640-1200 V DC), including product codes and overload capacities at 40°C.
Type Code Key
A breakdown of the type code key for VACON® NXP Grid Converters is provided, explaining the significance of each segment in the code, such as nominal current, mains voltage, control keypad options, enclosure class, EMC emission level, and cooling type.
Grid Converter Configurations
The document illustrates typical configurations for shore supply and shaft generator applications, detailing generator types, power units, filters, and software applications. It specifies shore grid harmonics requirements and equipment used on both generator and ship grid sides.

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 operate...

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 Converter...

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 power...

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, the...
