    Default Kulluk Salvage Operation

    This topic of this tread is discussion of the salvage of the Kulluk.

    Kulluk Response Ramps Up - a gcaptain

    the players are here (from gcaptain):


    • Aiviq, primary anchor handling vessel
    • Arctic Endeavor, oil spill response vessel
    • Nanuq, oil spill response vessel
    • Sisuaq, oil spill response vessel
    • John Brix, tug
    • Perseverance, tug/supply vessel
    • Endurance, tug
    • Ocean Wave, tug
    • Vigilant, Tug
    • Warrior, tug
    • Corbin Foss, tug
    • Point Oliktok, tug
    • Guardsman, tug
    • Lauren Foss, tug
    • DBL 79, oil barge
    • Klamath, barge
    • Barge 180-1
    • Arctic Seal, landing craft
    • Nunaniq, landing craft and supply vessel




    Talk of putting a wire on the Kulluk here


    In a statement emailed at 9:40 a.m. Saturday, the joint industry-government incident command said recovery teams planned to hook a main tow line to the drill vessel in preparation of attempts to pull it free from the gravel and rock it was resting in.
    I know there some Aiviq / Kulluk threads here already but I know there's lots of interest in the salvage itself.


    The blow by blow of the loss of the tow along with the second guessing is at MV Aiviq Breaks Down in Alaska While Towing Shell’s Arctic Drilling Rig

    After the tow went aground the tread is Kulluk Grounding which includes more second guessing and speculation about the condition of the tow and salvage plans.

    And for some trash talking about Shell and Nobel there is Is Shell Ready for Arctic Exploration?

    The tow plan... minus the details of course. I'm listening on the conference call now they said they did not tow today and are not giving details on the tow itself.

    Aiviq will do the tow. Awaiting a piece of tow equipment is why they didn't do it today. They will not lighten the kulluk, not remove fuel.



    Unified Command update:

    January 5, 2013

    ANCHORAGE, AK – Unified Command (UC) today plans to hook a main tow line to the Kulluk to test capabilities in preparation for recovery operations of the drilling unit. This plan will depend heavily on weather and tidal considerations.

    The UC also plans to deploy boom, as a precautionary measure, to Kodiak Island, with special attention being paid to salmon streams connecting to Ocean Bay.
    Unified Command has developed a wildlife protection plan to be used in the event that wildlife in the area is impacted during the recovery. They have activated International Bird Rescue to assist in bird rescue programs should their expertise be required. In addition, Protected Species Observers are being deployed on-scene.
    As previously stated, all plans rely on weather and tidal conditions.
    The Kulluk remains upright and stable with no reports of sheen in the vicinity. Salvage teams conducted an additional survey confirming all fuel tanks remain intact. Throughout all operations the safety of the responders will continue to be the top priority.

    Really, they expect it will pull off that easily? Seems way too optimistic but I guess it might although I would expect that they would need to deballast/dewater the rig requiring portable gensets and pumps, perhaps remove other weight aboard, rig beach gear to keep it from going higher up when you do, weld on lots and lots of strengthened points to hook up all those wires to, possibly need to remove lots of rock and gravel out of the tow path and out of the moonpool. And this is all without the hull fractured. If there's cracks, you have to weld lots of straps to keep them from getting larger and spreading after she starts to work when afloat.

    but why I am I writing any of this? Obviously, I don't know fuck all about anything. In fact I am a 13 year old girl who hopes to go to Kings Point someday so I can be a princess there!

    Fuck! With so many boats in Kodiak all at once, I wished I owned a bar in that town! From what I hear when the fleet was in Dutch, they damned near drunk the town dry. Probably Unisea's biggest profit center for the whole summer! Dick Pace's Grand Delusion Hotel finally paid off BIG! Too bad he wasn't around to see it reality.

    They didn't give much details in the call but it sounds like they are planning on using the Aiviq to just tow it off the beach. They said there is some water in the hull but don't believe its from any kind of breach.

    They scrambled nearly every available tug with suitable horsepower on the West Coast to go up there.

    I think its going to take a lot more than a few tugs to pull KULLUK off.

    I will say that they have been lucky that after the grounding of the KULLUK, the weather has been pretty benign all said. Had those wicked storms not hit like a string of freight trains rolling through AIVIQ would be almost all the way across by now. The thing is you don't do light on gear and hope for easy weather but rig to the max praying you don't get flattened when you tow in wintertime Alaska.

    I don't know anything about this but I'm not going to let that stop me.....

    Smit has experience pulling vessels off the beach.
    They may have a table with coefficient of friction based on the nature of the bottom or some such
    They can estimate the weight holding it on the beach from the loss of draft
    The beach there might be steep, in this case the distance to pull off would be less.

    They may have an estimate of how many tons bollard pull is needed to pull it off.

    On the other hand, even if they know they likely can't pull if off with just tugs what do they have to lose by trying? Meanwhile they can keep working on plan B.

    Likely someone else knows a thing or two about this.

    My 2 cents

    Smit is topnotch --- no doubt about that.

    As I understand it, salvage at that level is supported with calculations by engineers and naval architects who build detailed computer models.

    I suspect that 40 foot seas probably lifted KULLUK inshore quite a bit beyond her lightship draft. I doubt that they can offload enough to lighten KULLUK anywhere near enough to float her again.

    It makes sense to be able to get a good strain on KULLUK and be ready to pull just in case mother nature floats her again. The next storm could be SE and at high tide. Aftershocks from that 7.5 quake that happened yesterday might produce a small tsunami that might float KULLUK again.

    I'm not shocked that the unified command considered the risks of a spill during a lightering operation (from a vessel that apparently isn't leaking oil) and didn't discourage an initial brute force attempt without removing the fuel. We have to assume that there are some brains somewhere suggesting that a big pull might work and a single vessel pull apparently is feasible during the current weather window. I'd think that they could manage a multi-tug effort but what the hell do I know.
