The purpose of this short trip was to accommodate the Arctic-class drilling rig Kulluk, owned by Shell Oil, which arrived today in Elliott Bay after a two-week voyage from Dutch Harbor, Alaska. According to a report in Fuel Fix, Shell is moving the rig to Vigor Shipyard, where SBX-1 is currently based, for ongoing maintenance and planned, technical upgrades. Once Kulluk is berthed at Vigor, SBX-1 will return to its previous location for completion of the $27 million upgrade project that began in May.
The Kulluk was accompanied on its two-week journey from Dutch Harbor by Nanuq, a 300-foot oil spill response vessel that can store 12,000 barrels of recovered oil and has tools on board to collect crude from water. See http://www.akforum.com/eProceedings/oilspillresponse.pdf.
