Pipe and cable layers must by definition be capable to heave to in rough weather, precisely because they cannot cut and run. Tugs are seaworthy enough to go and help larger ships in trouble, in any weather. Announcing weather problems for either type of ship when the weather hits force 7, which is relatively tame by the way, is bullshit.
And how do they stop work part way through the pipe laying, when the pipe is suspended mid depth? What anchors the end of that pipe? The pipe layer hands the loose end to another ship, or just drops it loose and buggers off. Amazing that this 80 mile project is proving more difficult than the trans Atlantic cable laying operations.
Some of us have worked with ships long enough to know the situation.
