Rotterdam Offshore Group overhauls jack-up vessel Seajacks Scylla


Rotterdam Offshore Group (ROG) has overhauled world’s largest jack-up vessel, the Seajacks Scylla.

The upgrade work was carried out on the vessel during its visit at ROG’s terminal in Waalhaven after completing its deployment in the first phase of the Veja Mate Offshore Windpark project in the North Sea.

ROG adhered to the timelines while conducting the work which saw upgrading of the vessel’s mooring system.

ROG managing director Martin van Leest said: “We were very proud to have this unique vessel at our yard and believe the complete port of Rotterdam was also proud. The level of interest was high and even The Spido tour boats adjusted their route to visit the Waalhaven to see Scylla.  

“Working with the team at Seajacks was a pleasure and we created a real team effort to complete the project on time and to the highest specification.

“The crew on board really took good care of our employees. This good cooperation resulted in a maximum result possible. We hope to have Scylla back at our yard after she finishes her Walney project.”   

Following the overhauling work, Seajacks Scylla left for its deployment for the 2nd Phase of the Veja Mate offshore wind farm project at Esberg which includes turbine installation of 67 Siemens SWT-6.0-154 wind turbines at the 402MW wind farm.

The ABS-classed Seajacks Scylla has been designed to operate in the UK Round 3 offshore zones, Scottish territorial waters and the other North West European markets.

It is based on the Gusto MSC NG14000X design and can accommodate more than 8,000t of available variable deck load.

The Seajacks Scylla is equipped with a 1540t leg-encircling crane and a usable deck space measuring more than 5000m2.

The unit is fitted with 105m legs and can install components such as jumbo-monopiles, jackets, and turbines of future wind farms in water at a depth of 65m.
