Esgian Offshore Wind: monthly round-up October 2022

  • Cadeler signs agreements for O-class, F-class vessels
  • Vestas confirms multiple new facilities
  • California’s first lease sale to open December 2022

Vessel updates

Cadeler has signed a letter of intent (LOI) with an unnamed “blue chip” company related to potentially using one of Cadeler’s O-class vessels on a “significant long-term contract.” The LOI covers wind farm assignments off Northern Europe and in US waters. If finalized, the work will be undertaken after the vessel has undergone a large crane upgrade. The new main crane will have a lifting capacity of 1,600 metric tons at a radius of 40m and a hook height of 160m above the main deck.

Cadeler has also signed an agreement with an undisclosed client for use of its new hybrid F-class vessel from for a period of up to four years running from 2027 to 2030. The agreement includes a minimum guaranteed utilization and flexibility for the client to choose installation of foundations or wind turbine generators. If all options are exercised during the agreement, the potential value will exceed $320 million (€330 million). Furthermore, the agreement allows Cadeler the possibility of bidding on the transport and installation scope, which would increase overall revenues, if successful. The newbuild vessel is scheduled for delivery in Q4 2025. It has a previous agreement in place to install turbine foundations at the Hornsea Three wind farm starting in 2026. It will then commence this latest agreement.

Sembcorp Marine has cut steel on the newbuild wind installation vessel (WIV) for Maersk Supply Service. The vessel is designed to be stationed in one place at a windfarm to carry out successive installations, while tugs and barges ferry the turbine components out to the installation site, thus making the vessel Jones Act compliant. The WIV will also be capable of installing steel monopile foundations. Delivery into US waters is expected in 2025.

Shimizu’s Blue Wind jack up installation vessel held a naming ceremony on 6 October in Japan, and its first job has now been confirmed. After more sea tests, the newbuild will be heading to Venti Japan’s Nyuzen site in March 2023 to install three turbines before moving to Green Power Investment’s Ishikari Bay project. Blue Wind will have a capacity of seven 8MW turbines or three 12MW turbines.

InterMoor has been awarded the engineering design scope and the transportation and installation study for two floating wind farms off Asia. One project consists of 50-80 15MW turbines for a total capacity of 750-1,200MW, while the second project consists of 10-20 15MW turbines with a total capacity of 150-300MW. Water depths at the sites range from 80-140m. Each wind turbine platform will be moored using hybrid mooring lines, providing station keeping and offsetting extreme and ambient environmental loads.

Ramboll received a contract from Utilitas Wind to provide pre-FEED analyses for the Saare-Liivi wind farm in Estonia’s Gulf of Riga. The work scope covers technical solutions, electrical design (including cables), along with substation size and location, and analyses for port and harbour infrastructure. The study is set to be completed by early 2023. The first phase of the Saare-Liivi project targets 1,200MW of wind energy, using about 80 turbines. Utilitas Wind plans to obtain the necessary construction permits in 2025, and aims to bring the project online by 2028 at the latest.

Wind farm updates

Construction of the Hollandse Kust Noord wind farm commenced about 10 weeks earlier than originally planned, according to Van Oord project director Roeland Ris. The first of 70 monopiles were successfully installed, and the remainder are scheduled over the next few months. For the monopile installations, Van Oord has teamed up with DEME, which is using the installation vessel Innovation.

The Danish Energy Agency (DEA) has opened a supplementary five-week public comment period on the marine portion of the environmental assessment plan for the Hesselø offshore wind farm. The group behind the Climate Agreement on Green Power and Heat has decided to move the project to a more southern location. The strategic environmental assessment and the environmental impact assessment of the onshore part of the Hesselø project are unchanged and not part of this comment period.

After the period ends on 14 November, the DEA will decide which issues and environmental impacts should be highlighted in the marine part of the environmental assessment of the plan. A second public consultation will take place in the first part of 2024. If an environmental impact assessment (EIA) permit can be granted, it would take place in mid-2024 for the land-based portion of the project.

Meanwhile, the EIA for the marine portion of the project will be carried out in 2025-2026, once the winner of the tender has been selected. An idea consultation is expected in 2025, to be followed by a second public consultation in 2026. Later that year, the EIA permit for the marine portion is expected to be issued, if the assessment supports doing so.

X1 Wind has installed its PivotBuoy prototype at the PLOCAN site off the Canary Islands. Fitted with a Vestas V29 turbine, the 1:3 prototype has been installed at a 50-metre water depth in a downwind configuration, creating a passive ‘weathervaning’ effect that could eliminate the need for an active yaw system. The scalability of X1 Wind’s technology will enable the company to provide platforms for the 15MW scale wind turbines and beyond and deploy them at very deep sites, according to the company.

Virginia Attorney General Jason Miyares announced an agreement between the Virginia State Corporation Commission (SCC) and Dominion Energy regarding the Coastal Virginia Offshore Wind (CVOW) project. Under the terms of the agreement, initial construction costs of up to $11.3 billion will be shared between customers and Dominion. If construction costs fall between $10.3 billion and $11.3 billion, the split will be even. Any costs over $11.3 billion will be paid by Dominion in full. Should costs exceed $13.7 billion, the project will be reviewed by the SCC to determine viability and/or cost allocation. The agreement is subject to final approval by the SCC.
