Vigor Marine, a Vigor Industrial subsidiary, recently completed work on Barge Klamath, converting the vessel from a petroleum tank barge to an OSVR measuring 350’ x 76’ x 22’. The barge is owned by Crowley and leased to Shell as part of its comprehensive Alaskan oil spill response fleet in the Beaufort and Chuckchi seas. “Vigor’s extensive expertise in ice classing vessels for arctic waters, combined with the geographic proximity of their facilities, has made them a strong partner for Shell’s planned offshore operations in Alaska,” said Curtis Smith, spokesman for Shell Alaska.
