Abstract
A method and apparatus for allowing the simultaneous laying of at least two pipes from a pipe-laying barge using at least two coaxially aligned pipe tensioners, wherein a first pipe tensioner tensions a first pipe and allows a second pipe to pass freely through the tensioner, while a second pipe tensioner tensions the second pipe and allows the first pipe to pass freely through it. The apparatus preferably uses modified conventional equipment so that the barge will be able to lay large pipe with the conventional 'stovepipe' laying operation.
