Definitions

  • the invention relates to a method according to the preamble of the main claim.
  • the object of the invention is to provide a method for applying a protective coating on the inner surfaces of large containers, with which a much faster implementation of the coating is possible while avoiding the aforementioned disadvantages.
  • the method according to the invention has the particular advantage that considerable cost savings can be ascertained and that corrosion protection measures can also be carried out which have not previously been carried out for cost reasons alone.
  • a coating material such as that which is protected in DE-PS 24 12 453 is particularly suitable for coating the blasted inner surface.
  • the process for the corrosion protection coating of the inner surfaces of large containers is carried out in the following manner.
  • the working procedure is to be carried out on a tanker with several tank sections, it makes sense to fill several of these sections with fresh or sea water at the same time. Attention must be paid to the trim position of the ship.
  • the tank section must be filled to such an extent that the ceiling and part of the upper side surfaces remain free.
  • An inflatable boat is placed on the water through the open manhole, inflated and manned by the crew. Then the individual parts of an assembled and floatable raft are inserted through the manhole and assembled by the crew in the water. For this it is useful to use parts that are easy to assemble. Once the raft has been put together, the crew can switch to it. The crew then receives the blasting units necessary for the pre-treatment of the surfaces through the manhole.
  • the primer can be started with a moisture-curing coating material.
  • the top layer can then be applied immediately.
  • the coating work is carried out immediately after the blasting treatment. These steps continue until the tank bottom is also free of water.
  • the work raft is disassembled and removed from the manhole by rubber dinghy. The tank bottom is cleaned and coated and the crew is pulled out of the manhole using a winch. As the work progresses in the tank sections that were initially flooded and gradually drained, further tank sections are flooded in the same way. The coating work can progress quickly in this way.
  • a prerequisite for such a working method is a coating material that hardens even at higher atmospheric humidity.
  • other commercially available and suitable coating materials can also be used.
  • the same work steps described above can also be carried out when it comes to examining the inside surfaces of large containers for the condition of the anti-corrosion layer or only to carry out cleaning work. In this case, too, considerable cost savings can be achieved.
