What is shore power?

Shore power is a way of supplying electricity to a ship while docked at a port. Instead of relying on its own generators, the vessel connects to the local power grid through a shore power system, allowing the vessel to power all onboard systems and electrical appliances without running the engine. Therefore, it’s considered an important tool for reducing the environmental footprint within the maritime industry and improving air quality in port cities.

How does it work?

When a ship docks at a port equipped with shore power infrastructure, it connects to the local electrical grid via specially designed power sockets installed on the dock, usually located at the ships berth for easy access. The electricity from the local grid is then transmitted through connections to the ship’s onboard electrical system. It may undergo voltage conversion to match the ship’s electrical requirements. Once onboard, the power is distributed to various electrical systems and equipment, including HVAC (heating, ventilation, and air conditioning), refrigeration, navigation, and communication systems in the usual way. Shore Power can also charge the ship’s batteries!

What are the benefits?

Shore power reduces air and noise pollution by allowing ships to turn off their engines while in port, thereby decreasing emissions and noise levels. It also reduces expenses associated with running on-board generators, keeping costs as low as possible. Some ports may require ships to use shore power to comply with environmental regulations aimed at reducing emissions. Overall, it provides a stable and reliable source of electricity, eliminating the need for a vessel to rely on its own generators while docked.

igus’® role within shore power

igus® has been developing and manufacturing customised cable management systems for the maritime industry for many years. To ensure docks reach their maximum capacity, it’s essential that a ships’ berthing position is planned so that shore connections are not restricted due to unsuitable cable lengths. This is where igus® provides the flexibility necessary for your terminal and helps to minimise costs with the igus® mobile SPO technology. The igus® e-spool® is a low maintenance and inspection friendly motorised cable reel suitable for use in high-voltage or low-voltage shore power connections. It can accommodate up to ten rotations allowing it to run uninterrupted from the cabinet to a junction box!

Are there drawbacks?

As with many things, there are some downsides to shore power. Installing this infrastructure at ports can be expensive as the existing port facilities must be upgraded to accommodate the new equipment and not all ships are properly equipped or even willing to connect to it. While shore power has the potential to minimise the impact on the environment, this is only effective if the electricity being used is derived from renewable sources rather than fossil fuel power plants. So, its potential is dependent on many factors that need to be carefully considered when evaluating the feasibility and effectiveness of shore power projects but setbacks aside, this method of supplying power is likely to be an integral part of the future.

The future of shore power

The future is bright, with continued growth expected in its adoption and deployment across ports worldwide. As technology matures, regulations evolve, and awareness of environmental issues grows, shore power is ready to play a pivotal role in shaping a more sustainable and eco-friendly maritime industry. Therefore, widespread adoption will be dependent upon things such as economic feasibility and regulatory support to encourage co-operation from less convinced parties. With proven and trusted products, igus® can offer continued support and solutions to this industry.
