HOUSTON — As oil prices begin a slow climb, worldwide offshore construction vessel activity appears to be rising slightly alongside it. Derrick pipelay and pipelay barges continue to account for the majority of large construction vessel activity around the world.
Demand for derrick barges dropped in April before moving back to 28 in May out of a total 42 vessels, according to data gathered by ODS- Petrodata. This is down from a peak of 36 working units in October 2008.
Demand for derrick pipelay vessels in April also was up from February and stood at 31 in May. The offshore derrick pipelay fleet consists of about 50 vessels total.
Global pipelay vessel activity has been on the rise in 2009, going from 31 working in February to 37 in May.
