On May 20, 2011, Donjon Marine Co., Inc. contracted with the owners of the 42-ft cutter head suction dredge Robert R. Woodington to recover the cutterhead/ladder which was buried to a depth of 100 feet as a result of an underwater cave-in that occurred while recovering sand from an in-land sand pit. The cutterhead/ladder was covered by more than 70 feet of sand and clay mix. Donjon’s work plan was to mobilize a sectional barge equipped with a crane capable of handling a four cubic yard digging bucket, a 10-person salvage team including five salvage divers, and air-lift and jetting equipment.
