K Lindvig: I think when we compare it to the onshore wind where onshore is more the logistic thing and the transport, it’s the wind which is the challenging element. When we then go offshore we have a lot more elements to take care of. We have rain at the sea, we have the current and we have the tide. We, of course, have the same - the wind and wind speed and the wind direction as we have onshore, but we have more elements and we have a lot of combinations of those elements.
Then we definitely also have the challenge of the seabeds. Onshore you have the same, more or less, ground conditions as you have offshore. Offshore you can't see them. You can measure them. And you have to be able to operate on hard seabeds, on clay sand, stones, whatever the seabeds are, and that's also a challenging element to the offshore.
Vessels have to locate from location to location. It's not the same as driving a truck or driving a crane. Now we have ships and vessels which have to do that. And we have cables not dug in the ground where we more or less can see them; now we dig them into the seabed, and the seabed could even be moving due to scour or you have near to sandbanks and seabed conditions which are changing from one time to the other. So that is a lot of different things which are a lot more challenging on the offshore wind.
