Sunday 19 July the tug Kamarina with barge CC Atlantique carrying more than 8,000 tonnes of high voltage cable has safely arrived in Rotterdam, the Netherlands. The cables will form the connection of TenneT’s Hollandse Kust (Zuid) Alpha Platform to the onshore grid.

Blue Offshore is proud to be able to contribute to the Dutch energy transition, as it has been awarded the contract by Van Oord to supply a full cable transport spread for both the Hollandse Kust (Zuid) 2020 Alpha and 2021 Beta cable transport campaigns.

For this transport Blue Offshore has mobilized the world’s first certified double basket carrousel barge, with each carrousel carrying approximately 4,000 tonnes of cable. The transport took place from Hellenic Cables in Greece to the port of Rotterdam in The Netherlands. For this transport the 122m long barge CC Atlantique has been chartered by Van Oord. Besides two large carousels and the dedicated control systems, all deck engineering, technical crew and complete mobilisation service was provided by Blue Offshore.

In the upcoming phase of the project the cables will be loaded into Van Oord’s cable lay vessel the Nexus for the installation offshore. A spare cable will be delivered to TenneT in Eemshaven.

The Hollandse Kust (Zuid) Alpha grid connection must be ready in 2021. Beta is scheduled for completion in 2022. The HKZ wind parks combined will supply 1,500 MW of renewable energy, sufficient to supply up to 3 million households with power.
