Two members of the American Salvage Association (ASA) salvaged a sunken tugboat in Port Arthur, Texas on December 31, 2007. The 600-ton capacity derrick barge, owned by one ASA member, and another 700-ton capacity derrick barge, owned by another ASA member were
used to make a tandem lift of the 105-foot sunken tugboat.
The two companies initially responded to the sunken vessel with a salvage support barge used for diving survey and rigging operations. Once the diving survey and salvage rigging phases
were complete, one derrick barge was connected to the bow rigging and the second derrick barge, which was mobilized from New Orleans, Louisiana for this Salvage effort, was connected to the stern rigging. The two derrick barges then lifted the tug for the purpose of dewatering, refloating and subsequent redelivery of the vessel to owners.
