After several months of planning, engineering, and on-site preparations the sunken derrick barge DB1 was raised by executing the heaviest salvage lift ever accomplished in the Americas. The barge initially sank in a storm when its anchors dragged and the oil platform that it was removing tore out the bottom of the DB1 barge.
For the removal project, key-assets were used including the patented heave-compensated chain puller lift system deployed from the Conquest MB1.
After extensive preparations including the installation of heavy rigging under the DB1, the lifting gear was connected and the DB1 was steadily raised to the surface
