    A good illustration of Anchor Handling operation in good weather.
    This is the famous, but now wrecked, AHT Typhoon handling anchors for McDermott's Crane barge "CB 30":

    Aside from a tribute to the Typhoon it is a good illustration of how anchor handling is done the traditional way, using pennants and suitcase buoys, not chaser.

    She sunk in Bonny River, Nigeria on 05. Nov. 2013. Here is a link to the Wrecksite page about the tug Gudri:


      Clockwork team work in that first video.

      Thou canst not then be false to any man."


        More Anchor handling.
        This time the modern way, using two cranes with manipulators running on the cargo rails:
        Minimal man handling for minimal risk:

        Working on deck in rough weather can be dangerous:

          More tutorials.
          Pipelaying by the traditional S-lay method and all manual welding:
          The days when all Offshore Pipe welders came from Oklahoma is long gone.

          Deep water pipelaying by the J-lay method:
          This is the system on board Saipem 7000, with auto welding.

          Here a boring video showing the welding process, using all automated gas welding system:
          Also on the Saipem 7000. (Please ignore the stupid acting of the Iban riggers on break)

          Spool piece installation:
          It is very quick and easy in animation


            A popular way of laying pipelines in very deep water is by Coiled or Spooled pipelaying from very large and sophisticated vessels.

            Here is one of the largest and most advanced yet:

            The process of preparing pipelines at the Spooling Base at Vigra, Norway:

            Spooling pipe onto the reel:
            Not at Vigra.

            Another large pipelaying vessel, including a short cut of pipe being laid from the spool:


              Jacket installation in Danish waters:

              Noticed that the Riggers are all Ibans from Sarawak, East Malaysia??
              They are regarded as the best in the world for this kind of work. All major Offshore Construction Contractors are using Ibans where possible.
              They are hard working and doesn't complain for every little thing.


                More Marine Operations.
                Loadout made easy in Korea:

                Load-out, transport and installation in Norway:

                The activity for Saipem 7000 in 2013:

                Do I miss being part of this type of operations??? No, not really. I'm too old for this sh**.

                  All of this stuff is amazing to watch, all seems so calm and controlled. But to think of all the calculations involved in making such operations possible, that must be the real clever stuff.

                Ombugge and Janihudi - poor old chaps, it's heartbreaking to see them struggling along!

                "To thine own self be true.......
                Thou canst not then be false to any man."


                  OK, OK, I'm not really complaining about age, it's just something you have to adjust to.
                  This kind of high pressure jobs, even if everybody looks relaxed, is just not for me any more.
                  Been there, done that. Now younger people can take over. I'll do the simple stuff.

                  By the way, here is one more lifting operation, this time in the GOM:

                    I did post some still pictures from the attempted salvage of the bow section of MOL Comfort before (Post # 29).
                    Here is a video shot from the salvage vessel Capricorn:

                      In yesterdays Maasmond New Clippings the "Picture of the day" showed the Accommodation unit Safe Astoria arriving in the Malampaya Field, off Palawan in the Philippines.
                      This reminded me that I had a lot of pictures from her departure from the Mega Yard in Singapore two weeks ago.
                      This was originally the semi-submersible Drilling Rig SEDCO 602, built in Singapore in 1983 and worked mainly in S.E.Asia until she was sold to Consafe AB, Sweden in 2004 and converted to Accommodation unit at Keppel FELS in Singapore in 2005 and upgraded in 2012:

                      I have had a long relationship with this one, first as a competitor for drilling assignment in the lean times in the early 1990s. SEDCO for a shallow water drilling operation because this class of rigs (SEDCO 600 design) was able to sit on bottom. I was managing an old jackup at the time and was beaten with a VERY low bid from SEDCO.
                      Later I attended several times as UNOCAL Marine Rep. on SEDCO 602 when operating in the Gulf of Thailand.

                      In 2004 she was laid up in Pasir Gudang, Johor, when she got sold to Consafe. I attended the tow-away from there and approved her for a dead tow to Singapore. Because most of the drill equipment was removed she was down by the bow and light on the stern, so I instructed them to tow her "a*se end first", which she did on her last trip as SEDCO 602.
                      Here is some pictures from the departure from Pasir Gudang.

                      Draft on the Bow:

                      Draft on the Stern:

                      The derrick and Drillfloor was still standing:

                      Hooking up tugs at the stern:

                      Turning around:

                      Under way to Keppel FELS Shipyard, Singapore:

                      PS> The temporary Navigation lights had to change sides as well.


                        Here she is seen at Sembmarine's Mega Yard at Tuas South more or less exactly a 10 years later:

                        Tugs arriving to tow her out from the yard:

                        Two tugs at the stern:

                        One at the Bow:

                        Unmooring crew ready on the pontioon:


                          All ready to go:

                          Last line gone. Moving out:

                          Moving away from the spacer barge. Tow tugs Fwrd. and two tugs aft:.

                          A*se end first this time too, but she will be turned when reaching "open water" outside the yard area and handed over to the Ocean Tug at the Pilot Boarding ground.


                            From Maasmond News clippings today; here is how the new Pieter Shelte will work when removing platforms around the world:

                            This is now a major business in the North Sea and GOM and will become so in other mature oil patches around the world.


                              now looked again the video,this afternoon i was passing a terminal and there layed 1 big piece of iron,with something red at front.
                              i think i saw the first arm with claw for this vessel ,which will acording plans arive in Rotterdam last week of novenber.
                              it also seems that they are already making plans for a bigger vessel.there are now 12 oil platforms in the northsea, that even the ''pieter schelte'' can't remove
