Seajacks Scylla approaching completionVessel & ROV News // September 14, 2015
UK-based Seajacks is shortly to take delivery of its latrgest, most capable vessel. Seajacks has been expanding steadily since 2006 and will soon own and operate five advanced, harsh environment-capable self-propelled jack-up vessels – Kraken, Leviathan, Hydra, Zaratan and its latest newbuild approaching completion, Seajacks Scylla, which will be the largest vessel in its fleet.
Seajacks Scylla, based on the GustoMSC NG14000X design and scheduled for delivery in late 2015, was designed to meet the demands associated with working on UK Round 3 projects, in Scottish territorial waters and the growing northwest European markets.
The new unit will have more than 8,000 tonnes of variable deck load. It will be equipped with a 1,500-tonne leg-encircling crane and have a usable deck space of in excess of 5,000m2. Seajacks Scylla will be capable of speeds greater than 12 knots and will be outfitted with 105m legs that will have the ability to install components in water depths to 65m. It will be capable of meeting the installation needs of jumbo monopiles, jackets and turbines of future windfarms in deeper waters and further from shore.
ABS will class the installation vessel with notations that include the Wind IMR notation, which applies to offshore wind turbine installation units, ACCU, which applies to automatic centralised control unmanned units, DPS-2 for dynamic positioning capability and CRC for crane register certificate.
August 2015 saw all four of the jack-up legs fitted to the new unit at Samsung Heavy Industries.
In July, the company announced that the vessel had been contracted by WindForce – a joint venture between Royal Boskalis Westminster and Volker Stevin International (VolkerWessels) – for the transport and installation of 67 monopiles at the 400 megawatt Veja Mate windfarm.
