Esvagt Dana proves itself in the Baltic

In early spring, Esvagt Dana began her third charter as an SOV on the EnBW Baltic 2 offshore wind farm in the Baltic Sea. Esvagt Dana, originally designed and built as a crew change vessel, has adapted well to the new role, stated vessel operator Esvagt. The Baltic Sea was the perfect element for Esvagt Dana, proving its worth as an SOV despite tight storage facilities.

"There is slightly less space for cargo goods on the deck of Esvagt Dana compared to ESVAGT's other SOVs, but otherwise there is not much difference",
said captain Viggo Hvidberg. "We have become accustomed to working around the challenges it can present and just get on with the job. And it has worked well."

Optimizing space

Daniel Fisher, Baltic 2 Operations Manager with Siemens Gamesa, agreed with the sentiment, remarking: “The limited storage capacity has been the biggest headache. Other than that, the vessel has performed well”, he says: “Depending on the work you need to do, the lack of space can be limiting factor, and were you to do a lot of repairs in a wind farm and in need of additional storage for spare parts, then it becomes an issue. But for servicing and more standard campaigns the vessel works very well. We have been operating at full capacity with close to 40 personnel on board in the last weeks, and with an eye for optimising the usage of space, the operation has run smoothly”, says Daniel Fisher.

Great versatility

Siemens Gamesa has previously chartered the special build SOV Esvagt Froude. According to Daniel Fisher, Esvagt Dana is not too far off that mark. “In terms of accessibility to the wind turbines via the gangway, the ‘Esvagt Froude’ offers a bit more stability and is faster in connecting with the turbine than the ‘Esvagt Dana’. But the ‘Esvagt Dana’ makes up for it with gangway access to both sides and an improved crane”, he said.

The crane can lift 3 tons at 20m, enabling the vessel to deliver cargo at the turbine.

“It is very effective and combines well with the STB12 in creating an efficient operation ... Often we were able to put three or four teams of technicians on the turbines in the park with our STB12 within an hour",
stated Viggo Hvidberg.

Prior to the assignment on Baltic 2, Esvagt Dana worked in the offshore wind farms Merkur and Horns Rev 3. The vessel has also shown its flexibility by performing a successful job as a diving ship and base for Vår Energi's operations in the Goliat field. “We have tried the ‘Esvagt Dana’ in quite a few scenarios now, and it is a very versatile vessel”, added Hvidberg.

ESVAGT is a dedicated provider of safety and support at sea and a market leader within offshore wind solutions. It supports the offshore Oil & Gas industries with a wide range of specialised services. It also services offshore wind farms and have a fleet of dedicated Service Operation Vessels (SOV), which ESVAGT pioneered in 2010. The SOVs provide accommodation for technicians, spare time facilities, offices and conference room, storage for small turbine parts, workshops, etc. The SOV offers flexible personnel and equipment transfer capabilities by either Walk-to-Work gangway system or Safe Transfer Boats.
