It should also be mentioned that the deck module/hull module 8, 18 can be built in two or more parts, and be put together on the top of the hull structure 2 by "deck mating". The principle of self-floating deck module/hull module makes disassembling of the deck/hull module very simple by the fact that the installation method can be reversed.
  • the solution minimises the costs in connection with marine operations, together with optimising of the fabrication by making the deck module and the hull structure to the highest possible degree as separate units with as little "hookup" as possible.
  • a new built deck/hull module can to a high degree be simplified because the forces during installation are considerably lower then by use of lifting and temporary barges.
  • the force distribution during installation is as much as possible the same as the force distribution during operation, because the deck module/hull module is supported over a large area at the top of the hull structure.
