Seajacks and Samsung Team Up for World’s Largest Offshore Wind Installation Vessel


Seajacks International has entered into a contract with Samsung Heavy Industries to build 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.

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 1500 ton leg-encircling crane, incorporate usable deck space in excess of 5000 square meters, and have over 8000 tons of available variable load.

Sailing at speeds of 12 knots-plus, Scylla will be outfitted with 105-meter-long legs that have the ability to install components in water depths of up to 65 meters.

“Seajacks Scylla is a significant milestone for Seajacks and for the offshore wind industry,” Blair Ainslie, CEO of the Seajacks Group, said. “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 … 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.”

Seajacks Scylla will be delivered in the second half of 2015.
