High Voltage Shore Connection System Onboard and On-shore Emission-free Power Supply

 Open the catalogue to page 1

Container Solution Increasing pressures on ship operators and port authorities to minimise the impact of air pollution and noise emissions by way of meeting strict environmental regulations are now a worldwide concern. One particular solution for reducing emissions during port docking is the use of high voltage onshore power supply systems (HVSC) also variously known as cold ironing, alternative marine power, shore supply or shore power. As such, shore power covers provision of shoreside electrical power to a vessel while its main and auxiliary engines are turned off. As a result this solution...

For retrofitting of existing vessels Wärtsilä SAM is providing container solutions as well as single components for installation on board. Due to the use of 40' high cube standard containers, a flexible location on board is possible. On request or depending on the project, a solution with 20' container is also available. For low voltage applications we are offering a solution with step-down transformer (SCS-TR). The components are either installed in different locations on board or combined in a container. The following equipment could be installed in a container: n Cable reel [SCS-CR] n Cable...

Single Component Solution The SAMCon system consists of several modules as there are: Management and control cabinet [SCS-MC] Cable reel [SCS-CR] including n Interface for safety interlocks between shore and ship installation n Communication between ship and shore, scope of information to beexchanged according to individual port specifications n Interface to ship automation system n Medium voltage cable including fibre optic-, control cable and protective earth n Plug, incl. power-, control- and fibre optic cable contacts for shore connection according to standards required by individual ports...

High Voltage On-shore Power Supply System (OPS) Most of the international operating vessels calling ports in Europe, Far East and America are equipped with 60 Hz power supply systems. Against this European harbors are equipped with 50 Hz power grids. This doesn’t match! SAMCon provides solutions to allow vessels to be connected to shore by using frequency conversion to adapt the different type of vessels to shore regardless of the local grid frequency. SAMCon consist of key components like, stateof-the-art switchgears, low loss frequency converters and power transformers, control and protection...

High Voltage On-shore Power Supply System (OPS) At the beginning of 2009, the Wärtsilä SAM Electronics project team was able to realise the first complete onshore power supply system, supplying container ships with electrical energy from shore, converted from 50Hz to 60 Hz, in Antwerp ( Belgium). Frequency Converter and switchboard at terminal The on shore 50Hz/60Hz frequency converter is fed from the 15.5kV utility network via circuit breaker and step-down transformer (15.5kV / 690V). The frequency converter is based on a platform of Wärtsilä SAM standard PWM inverter systems (pulse width modulation)...

The essential control voltage for the converter, the PLC’s power supply (programmable logic controller) and the switchboard control voltage are powered by a UPS unit (uninterruptible power supply). In case of utility voltage drop, the converter will either stay on continuous working operation or will shut down safely, dependent on the dropping duration. The shore supply and converter systems are controlled by two microprocessor units. One unit belongs to the converter, the other PLC unit belongs to the control cabinet on ship side. The PLC’s are connected via fibre optic core, which is integral...
