For existing terminals, retrofitting shore power is not only a challenge in terms of planning but is also very cost-intensive. Ports already equipped with shore power often carry out detailed analyses of the incoming ships in order to determine the connecting positions as exactly as possible and to save costs. Subsequently, SPOs are built in every 100m to 120m as fixed installed systems in the quayside.
Today, however, new and larger ships that have installed a cable guidance system on board amidships put into these harbours. It is often the case now that SPOs can no longer be reached. Whether new shore power connections have to be planned or existing ones expanded, adding stationary SPOs is so cost-intensive that alternative solutions are called for.
Find out how you can use the igus e-chain reel to create a safe and permanent solution, and design your shore power supply system flexibly to meet the needs of the future.
When new terminals are being planned, stationary SPOs need to be considered at an early stage. As the extension length of the cable guidance system on board the ships is restricted to 35-55m, a stationary SPO has to be installed every 30-50m. For a terminal of approx. 400m in length, this means that 8-15 SPOs have to be installed.
All SPOs have to be connected to switchgear in the distribution station. The costs are immense. Connecting the cables (10kg/m) that come from the ship involves a huge amount of work for the harbour personnel. Several people are needed to handle the cables. An alternative solution is a shore power supply system with mobile SPOs. With the igus® e-chain® technology for long travels, distances of up to 800m can be covered. The combination of shore power supply and power & data supply for the STS cranes offers further potential for savings.
