Donjon Provides Diving and Salvage Services to Dredge

Friday, February 08, 2008
Donjon Marine Co., Inc. uses its salvage and related emergency response service equipment, the 1,000-ton capacity derrick barge Chesapeake 1000 and 400-ton capacity derrick barge Columbia New York to supply heavy lift, diving and related salvage services to the dredge New York which sustained considerable damage after being struck by another vessel while in Newark Bay, New Jersey in January.

Donjon Marine, Co., Inc., was contracted by owners of the 200-ft.-long excavator style dredge New York to supply heavy lift, diving and related salvage services after the dredge was struck by the 669-ft. vessel Orange Sun while working in Newark Bay, NJ. The dredge sustained damage, which includs the loss of buoyancy at the excavator end, fracturing of the hull at the point of impact, as well as bending of two of the 3-6-ft. square, 100-ton spuds, effectively pinning the New York in place.

Over a seven-day period, Donjon mobilized six heavy salvage vessels, including its 1,000-ton capacity derrick barge Chesapeake 1000, pumps and related support materials, as well as a salvage and dive team. Upon Donjon’s arrival onsite and after Donjon divers placed a lift sling around the hull of the New York, the Chesapeake 1000 provided a significant lift force to the vessel in an effort to provide stability during a subsequent dewatering effort.

Once the vessel was refloated, Donjon’s dive and salvage teams cut away the damaged sections of the 100-ton spuds, under water, so that the vessel could be freed from the bottom and delivered to a local shipyard for survey and repair. Once the spuds were cut away, Donjon’s 400-ton capacity derrick barge Columbia New York recovered the spud tips and made delivery of them to the repair facility. Donjon also removed the third, undamaged spud from its well on board the New York to increase vessel stability for the transit portion of the operation. After seven, 24-hour workdays the dredge New York departed the site and was delivered to a shipyard without further incident.
