I can add maybe one thing. I think there is still a conscious effort by government, in trying to align the various ships and work packages, to try to avoid this as much as possible, but I think that at times, despite some of those best efforts.... If one thing gets delayed, and through the tendering process more time is needed, we then, unfortunately, end up with the situation you describe.
I know there is still an effort. I'm not the marine expert either, but in speaking regularly with my colleagues, I do know they are trying to avoid that as much as possible.
