DEME signs with Port of Thyboron for Marshalling Vesterhav Nord and Syd Foundations

DEME and the Port of Thyboron have signed a contract concerning the installation of foundations for Vattenfall’s Vesterhav Nord and Syd offshore wind farms. marshalling of the 41 foundations for the 8.4 MW Siemens Gamesa offshore wind turbines will be in the Port of Thyboron.

The 77 m long monopiles, each weighing around 622t, will be produced by EEW in Rostock, Germany. The associated transition pieces (TPs) will be produced in Aalborg by Bladt Industries A/S. Each TP will be 22.5 m high and weigh 275t. The foundations will be shipped on barges in sets to the Port of Thyboron during spring. DEME’s large installation vessel, Innovation will load the foundations at the port.



DEME’s project manager, Jan Van de Velde, sees great opportunities in the project quay at the Port of Thyboron, with solid heavy-lift facilities and lots of quayside space. He notes: “There are clear advantages in the fact that we can work undisturbed at the quay in Thyboron throughout the installation project, and without disturbing others as we work at the port.”



This is the first time such a large offshore wind farm installation project will be serviced from the Port of Thyboron. By choosing the port for the installation, DEME and Vattenfall AB are actively contributing to the expansion of port capacity near the North Sea, in relation to the future need for large quayside areas and deep water in the offshore wind energy sector. There has been close dialogue and  cooperation between DEME and the Port of Thyboron on the project for a long time.



It is part of the Port of Thyboron’s strategy to develop the port in close cooperation with its users. The close cooperation with DEME during this project has given the Port of Thyboron a valuable foundation for yet another expansion that supports the sector. This has resulted in the establishment of a new 11 m deep channel from the North Sea all the way to the offshore project quay facilities at the port.

“As a port, we have found DEME to be a very professional and serious partner who has helped push us the last mile. In all modesty, we have also shown that a port like Thyboron can deliver the conditions we have promised. We are proud of this,” says Director Jesper Holt Jensen from the Port of Thyboron. “When Innovation arrives probable on 18 February to pick up the first 4 foundations for Vesterhav Nord and Syd, it will be a day of celebration at the Port of Thyboron.”



Jan Van de Velde, from DEME reports: “At Vattenfall´s business-to-business meeting with potential local suppliers in Thyboron, we perceived a potential to optimise the installation project using the good project quay facilities we saw with our own eyes during our visit. The Port of Thyboron has some unique port facilities for offshore installation. The open dialogue we have been able to have with the Port of Thyboron about the project preparations has also been outstanding. Our engineers have prepared everything down to the smallest detail. We are fully at ease about being the first to operate on such a large scale at the Port of Thyboron, and are pleased to be able to advance development through our choice of port and contribute to greater port capacity for the many projects being planned for the North Sea in the future.”

The Port of Thyboron currently offers 300,000 m2 of quayside land for storing primary components, a quay with a load bearing capacity of up to 23 tonnes per square metre, and now also a channel up to 11 m deep from the North Sea to the project quay facilities in Sydhavnen. Given the port’s location as a natural harbour inside the Liim Fiord, it has further potential for greater capacity in the form of port expansions that add more quayside land and quays in the long term.
