Wärtsilä helps ship operators and port authorities to meet increasingly
stringent environmental regulations by enabling ships to meet their electrical
power requirements, even when the engines are shut down. By taking electrical
power from shore, instead of from the engines, there are no exhaust emissions
or noise pollution. Wärtsilä Shore Power solutions are available in a built in shore power system or a deck mounted container configuration.
The shore power system is standardised in a globally applicable norm the IEC 80005, so that all commercial ships and ports can easily connect. The highest adoption have high voltage solutions (6.6kV or 11kV). The IEC 80005 explicitly covers container ships, cruise ships, Ro-Ro cargo ships, LNG carriers and tankers. The rules can easily be applied also to PCTCs, ferries and mega yachts. All other vessel types like bulkers or offshore vessels use a low voltage shore power system, also standardised in the IEC norm. Wärtsilä has solutions for all above mentioned vessel types. Many cruise vessels have shore power solutions onboard.
The most progressive segment for shore power is and has been the Container vessel segment as Los Angeles Port has started already in 2014 to make use of shore power mandatory for increasing share of the fleet calling Los Angeles. The state of California, USA is extending the 2020 requirements that covered container ships, “reefers” (carrying refrigerated cargo) and cruise ships. The updated regulation adds auto carriers and tankers. And the Chinese Government also recommends that shore connection systems - or 'cold ironing' - be provided by all new bulk and cruise terminals. The EU Fit For 55 published in July 2021 includes provision for shore charging which will further drive the expansion of shore charging.
The SPC system with all the necessary components is completely containerised. This standard 40ft high cube container can be installed in any suitable location onboard the vessel. However, if requested or required by the project, a 20ft container solution is also possible as a single component solution. For low voltage applications, our solution can include a step-down transformer. Furthermore, for retrofit applications we offer complete onboard installation with a connection to the existing main switchboards.
Wärtsilä provides the following services for both retrofit and newbuild projects:
Since certain projects require a customised solution, Wärtsilä also offers a single component solution. This enables flexibility whereby the main SPC components can be installed in different locations onboard the vessel. As example the shore cable reel will be install in a 20ft container on deck while the Monitoring and Control Cabinet and the Medium Voltage Switchboard will be install in a different location under deck or in a second 20ft container on deck. We have a lot more options and solution for your special project.
For both onboard container installation and single component solutions with connections to the main switchboard, Wärtsilä offers the engineering and installation services for the below listed items, including the foundations, cables, cable trays, and any additional materials needed onboard the ship.
For the bolted SPC version, the following connection box is available:
For the pluggable SPC version, the following connection boxes are available:
Connection to the vessel's main switchboard is made by modifying the existing panel, or by building a new panel for low and high voltage switchboards, including the protection device and power management.
For vessels equipped with a Wärtsilä shaft generator system, we offer a retrofit solution utilising the main components of the installed system. Instead of taking the feed from the shaft generator, the system is extended via a shore connection.
