Abstract

Deep-water wreck cargo recovery method using a heavy-duty pincer assembly (2) deployed from the drill string (3) of a dynamically positioned drill ship (1) and controlled via an underwater module (6) fitted with propulsion means, as well as a shock absorbing device (10) in the lower portion of the drill string. During the demolition stage, the pincer assembly rips open the wreck to provide access to the cargo. During the recovery stage, the pincer assembly is fitted with side walls and is used as a bucket. The method is particularly useful for recovering ores from modern ships and for recovering hazardous materials (e.g. radioactive materials).
