    Probably with less publicity though.
    They are now just passing Aalesund, but outside Storegga.
    PS> Being escorted by Boa Odin.

    Pretty amazing turn of events if you think about. We (more like "they") must be in a very desperate situation - and I know they are - to even consider this as their current and perhaps only option.

    The Aasta Hansteen SPAR is now moored in position with 17 anchor lines:

    Next the risers will be pulled in to connect it to the wells on the seabed and the Nordled pipeline to the mainlands.

    The change of tow configuration took place around 0300 hrs. this morning and resulted in an interesting track line:

    Now heading for the Gjoa position.

    They are out in open waters but haven't started reconfiguring or turning north yet:

    I used to do this for a living you know

    PS> They appear to do good without both me and Knut Lussand being there though.

    A little delay occurred during the night:

    But they are moving again now:

    Estimated to be in open waters this afternoon and changing to 4-1 tow configuration for the rest of the 500 n.mile tow up north.

    In the article quoted above there is a link to previous large tows performed in Norwegian waters, from the 1970's to 1997:
    https://sysla.no/maritim/fra-denne-c...hore-historie/
    These are all about tow performed for Norwegian Contractors, the builders of Condeep concrete platforms,

    One major towing operation that is not mentioned is the Ekofisk Barrier which was a Joint Venture between Dutch and Norwegian companies. (PECONOR)The tow and installation was performed by Nortow and Smit together in 1989: http://newsok.com/article/2269354

    Smit supplied two Towmasters while Knut Lussand from Solstad and Alf Giske from Farstad was towmasters for Nortow. (I was Project Mariner for the MWS team)

    This was a more complex operation than the Gullfaks C or Troll A in my opinion. We had the same problem with deep draft and narrow fairway for the coastal tow, plus shallow water enroute in the North Sea, but not the problem with overhead cables across the fjords.

    Our main problem was installation around the Ekofisk Centre while at full production, with pipeline going in and out at the subsided bottom and bridges to/from several other platforms.
    The installation tolerance was also a lot more critical, at 7.5 cm. (not 50 m. as for Troll A) We got 3.5 Cm from ideal Zero.

    PS> The picture of Knut Lussand in the "Command Container" at top of the article was actually taken during the Ekofisk Barrier tow, as can be seen from the drawing on the whiteboard.

    Tow of Aasta Hansteen SPAR has commence.
    It is kind of history in the making:
    • The largest SPAR in the world and the first in Norwegian waters.
    • The deepest field in Norway
    • North of the Arctic Circle. (But not the northernmost field)
    • The first time a SPAR is towed to field with the deck structure installed.
    • The largest tow in Norwegian waters since 1995.
    • A new generation key personnel performing the operation.

    Here is an article from Sysla previewing the operation:
    https://sysla.no/maritim/tirsdag-gjo...el-siden-1995/

    From Sysla today:
    The Aasta Hansteen SPAR tow is on the way out from Stord:
    Sysla will keep a running commentary with pictures and maybe some video of the towing operation as it progresses:
    https://sysla.no/maritim/folg-aasta-hansteen-slepet/ They will get to the most critical point in a few hours; passing under the cable fjord crossing at Langenauen

    You can follow the operation also on Marinetraffic:
