Built in South Korea by Samsung Heavy, Scylla is designed to install the next generation of offshore wind farm components, including giant 7MW and 8MW rotors and nacelles, and so-called XL monopile foundations.

"Scylla is the largest and most advanced installation jack-up on the market and is targeted at the offshore wind and oil and gas markets. The vessel can handle XL monopiles, jacket foundations, and is able to transport an impressive number of the 7MW and 8MW turbines that are currently available in the wind market," states Seajacks chief executive Blair Ainslie.

The jack-up – which features a Huisman 1500-tonne leg-encircling crane and has 5,000 square metres of deck space with 8,800 tonnes of variable load capacity – can work in water depths of more than 65 metres courtesy of its 105-metre legs.

In early December, Scylla will journey from South Korea onboard the heavy-load HLV Osprey to the Netherlands, to be readied for work by the Seajacks operations teams.

Scylla has its first assignment off the UK in 2017 at Dong Energy's 660MW Walney Extension offshore wind farm, being built around MHI-Vestas 8MW V164s and Siemens 7MW SWT-7.0-154s.

The vessel joins a jack-up fleet that includes the Seajacks Kraken, Leviathan, Hydra and Zaratan installation units.
