Seajacks Orders Giant Wind Farm Installation Vessel

Seajacks International contract Samsung Heavy Industries to build what they claim to be the world’s largest and most advanced offshore wind farm installation vessel.

The vessel has been specifically designed to meet the demands associated with working UK Round 3, Scottish territorial waters and the other North West European markets. Seajacks also has options for the construction of an additional two units. The new construction vessel will be delivered in the second half of 2015.

Named Seajacks Scylla, the new vessel is based on the Gusto MSC NG14000X design and will be the fifth new self-propelled jack-up to join the Seajacks fleet since 2009.

The vessel will be equipped with a 1500t leg-encircling crane, incorporate useable deck space in excess of 5000m2, and have over 8000t of available variable load.

Sailing at speeds of 12 knots or over, Scylla will be outfitted with 105 metre long legs that have the ability to install components in water depths of up to 65m.

Blair Ainslie, CEO of the Seajacks Group, said:
“Seajacks Scylla is a significant milestone for Seajacks and for the offshore wind industry. She is a Round 3 vessel and is more technically advanced than any other installation vessel that we see on the market today.
Drawing on our extensive experience, and based on feedback from discussions with clients across the supply chain, the design of Seajacks Scylla has been developed to meet the installation needs of jumbo-monopiles, jackets and turbines of future wind farms in deeper waters and further from shore.


Since 2009, Seajacks has developed a track record of over 830MW of turbines installed and is currently constructing an additional 288MW at the Meerwind Offshore Wind Power Project in Germany. Based in Great Yarmouth (UK), Seajacks were acquired by Marubeni Corporation and Innovation Network Corporation of Japan in May 2012.
