    Re: Floating cranes and other lifting ships

    Amazing pictures from these enormous floating crane barges around the world

    "Eide Rex" towing "Eide Lift 6" south to Kristiansund at noon today.
    She comes from Rypefjord outside Hammerfest.

      The "Eide Rex" I have no recollection of. I believe she was originally German though??

      The "Eide Lift 6" is the old "Conlift", belonging to Norwegian Contractors. I have spent many weeks on that one, laying 120 mm. chain moorings in Aalfjord and Vats in the summers of the late 1980s. The crew on Conlift was some of the most professional I have ever worked with.

      She is (was?) capable of testing anchor holding to 1000 m.t., single leg (2000 m.t. double) using the hydraulic rams and the large "Wheel" you see at the bow.

      The most I have been involved with was 550 m.t. though. When an anchor slips at that kind of tension a lot of spectacular things happen, I can assure you.

        Isn't that near the breaking strength of K4 chain ?

        We experienced a 500t+ recorded tension on a chain of a flotel once.
        And nothing happened. Doubt that the tension was real.
        But that chain broke in the next storm, about a week later.
        Luckily on the windward side. The rig had a 12 anchor spread.

          It's always nice to see an old workplace sail by, and are in full operation

          According to Miramar ship index was "Eide Rex" originally built as tug "Duchray" in Leith and was completed 28/10/1975.

          She became "Eide Rex" in 1998.

            You are probably talking about 76 or 84 mm. diam. rig chains?

            I was the Warrant Surveyor on two jobs using the Conlift, the Gullfaks C at Vats and the Ekofisk Barrier at Aalfjord.
            We were working with 120 mm. chains in shots of 27.5 m. being laid in fairly deep water, (up to 3-400 m.) but also some connected to shore based piles, grouted into solid granite.

            In Aalfjord we used 40 t. Stevmanta anchors, but ended up having to piggyback and add cement clump weights to several lines due to boulders on the bottom.

            I watched by ROV as an anchor slipped at nearly 550 t. tension. The anchor slowly raised up from the mud and then took off at a hell of a speed. Very spectacular, but not recommended watching for the faint hearted.

            At one occasion we got a boulder so solidly stuck in between the double flukes and the shanks that it had to be dynamited to dislodge.

            Good old memories of summer jobs in Norway in my younger days.

                          The crane on her deck looks like a toy compared to the main crane.

                            It is a rented 350 tons Manitowok, I believe.

                            PS> By the way, the 4200 tons rating of the "Big rig" is in Short Tons, not Metric Tonnes (3800 m.t.) Looks more impressive in S.tons, hence they all do that. (But not S-7000 and the Heerema SSCVs)

                            PPS> The top rating is when fixed, with tie-back and over the stern only. Fully revolving load is 3000 m.t. "only".

                            Correction; The crawler crane is a KOBALCO
