Vigor Marine Completes Work on the Kulluk and Noble Discoverer
The Kulluk and Noble Discoverer set sail for the Arctic today from Vigor Industrial’s Seattle shipyard, following completion of extensive environmental and safety upgrades by its commercial ship repair subsidiary, Vigor Marine.
The Kulluk, an ice-classed semi-submersible drill rig measuring 266’ x 230’, arrived at Vigor’s Seattle yard in July, 2011. Following the work done by Vigor Marine teams, it will operate with zero discharge in the Beaufort and Chuckchi Seas. Everything down to the sink water will be captured and stored. Even the blue and white paint scheme was chosen to accommodate the known preferences of whales.
The same care was taken with the Discoverer, a 512’ x 86’ ice-classed drill ship. The Discoverer arrived this April to undergo winterization and similar environmental upgrades. Vigor Marine mobilized a team of more than 500 skilled, quality-focused workers to complete upgrades which would normally take up to 6 months in just 10 weeks. In-house engineers worked closely with naval architects to accommodate additional requirements.
Vigor teams installed six EPODS, one on each engine. The 7’ x 20’ EPODs perform like catalytic converters in automobiles, capturing harmful discharges like carbon dioxide and nitrous oxide. The Discoverer’s emissions now meet the highest air quality standards in the world.
“Vigor’s work on the Kulluk and Discoverer has been outstanding,” said Curtis Smith, spokesperson for Shell Alaska. “Vigor’s capacity to provide the highest levels of quality work within our timeframe is impressive and continues to make them a valued partner in Shell’s Alaskan offshore operations.” The Kulluk and Discoverer are the latest in a series of vessels Vigor Marine has completed work on for Shell Alaska, including the Barge Klamath and Arctic Challenger, both OSRVs.
