Weather hampers operations at the grounded Kulluk.

Weather hampers operations at the grounded Kulluk.

Five salvage experts boarded the grounded drilling unit Kulluk early on 2 January to conduct a structural assessment to be used to finalize salvage plans, currently being developed by the Kulluk Tow Incident Unified Command.

The five-member team was lowered to the Kulluk by a US Coast Guard helicopter at about 10:30 am. The assessment lasted about three hours. A helicopter safely hoisted the team from the drilling unit at about 1:30 pm. The Coast Guard helicopter and crew also delivered a state-owned emergency towing system to the Kulluk, which will be used during salvage operations.

Efforts to place a team on-board the rig to conduct the assessment were put on hold due to severe weather conditions over the past several days. Calmer conditions this morning created a window that enabled the assessment to take place.

Smit Salvage is heading up salvage operations. Smit is a highly experienced salvage company that has assisted in hundreds of operations worldwide, including the Selendang Ayu salvage that took place off the coast of Western Unalaska in 2004. It also assisted in the Costa Concordia salvage off the coast of Italy in 2012.

The information gained from the on-site assessment will be invaluable in helping to evaluate the available options for freeing the rig from its grounded position. Following the completion of their mission, the assessment team was returned to Coast Guard Air Station/Kodiak.

“The weather on scene is testing the limits of our Coast Guard crews. The professionalism of our air crews and cutter men and women have prevented the situation from deteriorating further” says Rear Adm. Thomas Ostebo, commander 17th District in Juneau, Alaska. The 17th District is directing the rescue efforts involving multiple cutters, ships, and aircraft.

Watchstanders at Coast Guard Sector Anchorage were initially contacted by the crew of the Aiviq, a 360-foot tug on Thursday who reported that their towing hawser linking them to Kulluk had parted in heavy seas casting the Kulluk adrift. Aiviq was able to reestablish the two with another emergency towing hawser but subsequently experienced total engine failure casting both Aiviq and Kulluk adrift in the heavy seas and strong winds. Royal Dutch Shell directed the launch of the Guardsman and the Nanuq and Coast Guard 17th District directed the crew of the Coast Guard Cutter Alex Haley to divert from their patrol to provide assistance. The Alex Haley is a 282 foot medium endurance cutter homeported in Kodiak.

The Alex Haley arrived at the Aiviq’s location early Friday and successfully delivered a towline to the Aiviq which was still connected to Kulluk in strengthening 40 mph winds and building 35-foot seas at approximately 4:30 a.m. The Alex Haley was able to establish a tandem tow of Aivig and Kulluk preventing further drift of the disabled vessels towards shoal water. The heavy seas, strong winds, and sheer mass of both Aiviq and Kulluk created enormous challenges for Alex Haley to establish and maintain the tow. At approximately 6:30 a.m. the crew of the Alex Haley reported that the towline had parted and become entangled in the ship’s port propeller. The command directed the ship to return to Kodiak in order to make repairs. The tow line between Alex Haley and Aiviq parted due to the heavy strain created by the wind, seas, and displacement of Aiviq and Kulluk, however the effort by Alex Haley slowed the drift towards shoal water and bought extremely valuable time to enable further rescue options. “I applaud the can-do spirit of the crew of the Alex Haley. They accomplished the nearly impossible given the weather conditions and bought valuable time. Without their efforts the overall situation would be much worse than it is now,” said Ostebo.

The US Coast Guard, Royal Dutch Shell, State, federal, and local officials in Kodiak have stood up a unified command to be prepared in case any of the vessels run aground and potentially release any fuel. The unified command is closely monitoring the overall rescue operation and is preparing for any eventuality.

At approximately 9 pm Friday, Royal Dutch Shell contacted the Coast Guard and requested the removal of the crew from the Kulluk due to safety concerns for the personnel onboard in the rolling and pitching vessel in heavy seas. Additionally, Royal Dutch Shell requested delivery of parts to the Aiviq so they could make repairs to their engines. Aiviq’s engine failures were attributed to some poor quality fuel that had been isolated. Repairing Aiviq’s engines became the priority because Aiviq is the only vessel available on scene capable of towing Kulluk. The tug Alert from Prince William Sound is also capable to towing the Kulluk and will arrive on scene mid-day on Sunday.

Two Coast Guard MH-60 helicopters crews were launched at approximately 10:30 p.m to attempt the evacuation of the personnel from the Kulluk but were unable to hoist the crew because the 50 mph winds and 20 foot seas were causing the Kulluk to pitch and roll to such a degree that hoisting the personnel was too dangerous.

At approximately 5 am on Saturday, a MH-60 helicopter crew successfully completed the first delivery of engine parts to the crew of the Aiviq who began making repairs.

At about 7 am, Coast Guard MH-60 Jayhawk helicopter crews from Air Station Kodiak completed the delivery of engine parts to the crew of the support vessel Aiviq, in 30 mph winds and 20-foot seas. The total amount of repair parts delivered by helicopter is over 2000 lbs.

At about 9:30 am, the crew of the Aiviq was able to successfully make repairs to the ships damaged engine with the Coast Guard delivered parts and were able to keep the Kulluk from drifting closer to shoal waters.
