Seajacks Scylla Mobilising for Hollandse Kust Noord, Kraken Changing Out of Oil & Gas Attire Ahead of Offshore Wind Work

March 13, 2023, by Adrijana Buljan

Jack-up vessels Seajacks Scylla and Seajacks Kraken are currently moored in two Dutch ports, where they are being mobilised for offshore wind projects.

Seajacks Scylla arrived in the Port of Amsterdam on 1 March, according to the vessel’s AIS data available online, while Seajacks Kraken arrived in the Port of Den Helder on 11 March.

According to DHSS, a Dutch provider of integrated logistics to the offshore renewable industry, Scylla is getting ready for work on the Hollandse Kust Noord offshore wind farm in the Netherlands and Kraken will mobilise for an offshore wind project after completing a campaign in the oil and gas sector.

Offshore construction at the 759 MW Hollandse Kust Noord offshore wind farm, owned by a joint venture between Shell and Eneco, is well underway with all foundations installed and wind turbine installation up next.

Van Oord, the company responsible for the installation of the project’s TP-less monopile foundations, inter-array cables and wind turbines, booked Seajacks Scylla for 2023 work back in 2021.

In a recent social media update, DHSS said that Seajacks Kraken, also a jack-up vessel owned by Seajacks UK, a subsidiary of Eneti, was readying for an offshore wind project.

This vessel is demobilising from an oil and gas campaign in the Port of Den Helder, where it will also mobilise for offshore wind work, with DHSS assisting with Customs clearance of the vessel and equipment along with the port logistics for cargo and crew.

No information was shared on what offshore wind project is up next for Seajacks Zaratan.

Eneti and Seajacks have so far signed numerous contracts for the Seajacks jack-ups, including the three NG2500X-class wind turbine installation vessels (WTIVs) Seajacks Kraken, Seajacks Leviathan, and Seajacks Hydra, as well as the flagship NG14000X-class Seajacks Scylla and the NG5500C-class Seajacks Zaratan.

For most of the contracts, Eneti notes that they were secured for offshore wind projects in Northwestern Europe.

In June last year, Eneti announced that Seajacks had signed three contracts with Dogger Bank Wind Farm, the world’s largest offshore wind farm which is now under construction, for the charter of one of its NG2500X class vessels.

The contracts are for the support of offshore substation platform hook-up and commissioning work on all three 1.2 GW phases of the offshore wind project. The first contract is set to commence in the second quarter of 2023. After that, the vessel is scheduled to return to the wind farm in both 2024 and 2025.
