In the media there was information about the damage, Received floating dock PD-50, which took place repairs of the aircraft carrier "Admiral Kuznetsov". Recall, floating dock that sank after the failure of sediment, caused by problems in the supply of electricity. Murmansk region covered element, It occurred sticking of wet snow on power lines, caused numerous breaks. These factors are named formally causes problems with the supply of electricity at the shipyard and stopping of pumps.
water, hlynuv tank in PD-50, It led to the flooding of one of the largest floating docks in the world.
Recall, that the Minister of Industry Denis Manturov said Thursday, that the decision, raise or not to raise the floating dock, It will be made in the "next two days". Today - the last day, if we start from the Minister's statement.
meanwhile, there were reports in the media about, that the high probability of failure of the lift floating dock. The thing is, that divers, that the last few days engaged in research of the state of the PD-50, We established the presence of multiple injuries. So, "Interfax" news agency, citing unnamed sources, reports, that the floating dock hull was badly damaged when it strikes the ground during flooding. Marked by permanent loss of two tower cranes floating dock.
When this is added, It is now increasingly seen buying a PD-50 analog, instead of lifting the sunken dock. However, there is no evidence, one floating dock such dimensions can be ordered, and some time may be required for the project.
Recall, Earlier in the United Shipbuilding Corporation said the lack of impact of the incident with the PD-50 for scheduled repairs TAVKR "Admiral Kuznetsov". then it turned out, that aircraft carrier was seriously damaged in a fall tower crane. It declared the 5-meter hole in the hull and deck breakage sole carrier of the Russian Navy.
As a supplement: during diving operations found, that PD-50 nakrenon. One of its parts is at a depth of 10 m, other - about 30. In this case, the floating dock is at the bottom on the edge of the hole about a hundred meters deep. When performing work on the PD-50 lifting there is a danger, that the floating dock into this pit in the water area of the shipyard №82 spolzot and "carry off" for an equipment, which can be used during lifting. To date, prevents slipping of the air bubble, which was formed on top of the floating dock.
I worked in a ship repair 20 years. I know how to raise the dock, and at the same time to get a new dock.
I have worked in ship repair 20 plus years and I know how to raise the PD-50. I've seen it. require caissons. Produce rectangular caissons. number-considered. Height above water-considered,(perform shipbuilders). The technology works on the same next-caisson, caissons are joined next to the castle. Caisson plunges vertically. At the bottom of the sealing gasket set, which, when pumping the water seal external pressure flow of water inside the caisson. Draw off water from the caisson. Pumped concrete into the caisson, pre-setting the pipes as a guide for drilling columns, The diameter of the columns and drilling depth are calculated. Drilled through pipe, set columns. Caisson finally poured concrete. To him fit in the second caisson to the castle,(shipbuilders know). This operation is repeated. And just on the perimeter of the dock. End portion is removable. Draw off water from the inner perimeter and docking at a glance. Then, defect inspection and repair. At the end of the PD-50 to bring to a regular place. Close shutters and pump out the water. The result was a dry dock, who did not drown.
For these works under any sauce to avoid ineffective managers are not defective, Only professionals from the director to the storekeeper and Repairers. In my experience, the first yavyatsya adventurers and rogues, and only then will the specialists and it will go.
Raise possible without the caissons and require meager costs rise only work must be one of the military naval engineers rather than swindlers stupid managers RAISE quickly without a huge cost for a penny and do it not spolzot in any hole and oscho will serve decades Who wants to do that makes and who does not want one looks for reasons and excuses
Raise it is very easy
All ingeniously simple to operate only have military marine engineers and managers who do not drown anything they think only of profit do not need anything complicated and heavy types of caissons and other panky and do not need a thousand fools with two or more higher educations
