摘要：A method and apparatus for allowing the simultaneous laying of at least twopipes from a pipe-laying barge using at lest two coaxially aligned tensioners, wherein afirst 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 firstpipe to pass freely through it. The apparatus preferably uses modified conventionalequipment so that the barge will be able to lay large pipe with the conventional\"stovepipe\" laying operation.
