Early February TenneT marked the official opening of a special cable storage facility in Eemshaven.
TenneT explained that the facility’s location in Eemshaven is ideal for various reasons, including mooring space for vessels in front of the storage facility facilitating quick and efficient loading and unloading of cables.
These massive cables are used for subsea connections that link offshore wind farms to the onshore grid, and for offshore direct-current interconnectors like the NorNed cable.
The facility provides 2,309 m² of floor space, enabling the storage of up to 4,600 tonnes of high-voltage electricity cables. The cables concerned measure between 10 and 24cm in diameter, with weights ranging from 30 to 100 kg per metre.
The facility is also located near the converter station for the NorNed interconnector and the planned landing point of the COBRA project.
The storage facility includes two ‘turntables’ that are used to roll up the cables. Each turntable is divided into six sections, allowing storage of twelve different cable systems at any given time to a total of 2,300 tonnes.
