Wind farm support vessels: The Operators

OW10_totaal_2.jpg 21 0

With the unenviable task of selecting the right boat goes the privilege of leading the designers and yards to build the boats they want. While the hulls are built in different materials and with beam and lengths in various dimensions, the engines, propulsion systems and the fittings remain the choice of the buyer. Even then the hulls are not always so similar. The buyers can choose between single hull, the double hull catamaran, and even more, the triple hull trimaran. Offshore WIND has spoken to operators who have chosen some of these hull designs with different fittings.

Conclusion

This is not the first time we have said this and we sincerely believe that it will not be the last: There are no bad designs, or builds, or operators. You, as the decision-making reader of Offshore WIND, must decide what vessels you want to support your wind farm with and who you want to operate them for you. The operator must select the builder and the builder must select the designer.

There is only one disappointment in this chain and that is the lack of unity in regulation. It must be possible for the European Union and Norway, Lloyds, DNV, GL, BV, and any one else involved in classification, certification and regulation to work out a common format. If for no other reason than that it would be cost effective, the industry should work to get this sorted now.
