After jackup vessel Seajacks Scylla’s first successful assignment on phase 1 of the Veja Mate Offshore Windpark project, the vessel upgraded its mooring system at the Rotterdam Offshore Group (ROG) terminal in the Waalhaven.
ROG worked around the clock to complete the project within strict deadlines and to the highest quality levels required by the vessel owners and to class satisfaction.
After the upgrade, Seajacks Scylla sailed to Esbjerg where the vessel has been mobilized for the second phase of the Veja Mate offshore wind farm project which includes the turbine installation of 67 Siemens SWT-6.0-154 wind turbines at the 402 MW wind farm.
Seajacks Scylla had already completed phase 1 of the project, installing 67 foundation monopiles at the site located some 95km north west of the island of Borkum in the German exclusive economic zone (EEZ). Each monopile weighs approximately 1300-tonne, has a diameter of 7.8m and each transition piece is over 25m in length and weighs approximately 360-tonne.
Veja Mate is a US$2 billion (EUR 1.9 billion) offshore wind project expected to be fully operational by 2018 which will offset over 18 million tonne of CO2 over the life cycle of the installation.
“Scylla is now fully engaged in Wind Turbine Generator construction at the Veja Mate wind farm, and the high-quality installations committed by ROG have been key to making this happen,” said John Vingoe, operations manager, Seajacks UK.
Delivered by the Samsung Heavy Industries Shipyard in Geoje, Republic of Korea in 2015, Seajacks Scylla has been designed to operate in the UK Round 3 offshore zones, Scottish territorial waters and the other North West European markets.
Based on the Gusto MSC NG14000X design, the ABS-classed Seajacks Scylla, has more than 8000-tonne of available variable deck load. Equipped with a 1540-tonne leg-encircling crane and a usable deck space in excess of 5000sq m, the unit is outfitted with 105m legs with the ability to install components in water depths up to 65m. The rig is capable of meeting the installation needs of jumbo-monopiles, jackets, and turbines of future wind farms in deeper waters farther from shore.
