During the realization of an immersion tunnel in South Korea, a GINA profile got damaged. To guarantee a waterproof sealing of the tunnel elements, repair of the raptured rubber was necessary. This repair had to be executed in a dry environment, however the damaged GINA profile was located 12 metres below the water surface. Because of that, MH Poly had designed a waterproof habitat. This habitat is a dry environment, large enough for two persons, that can be slide/shift around the GINA profile, so that the repair could be executed.
For the design of the habitat
MH Poly considered the following items:
- Optimum size of the habitat: large enough for two persons. A larger environment also results in more buoyancy.
- Prevent of new damages: during the installation and removal of the habitat no new damages may occur.
- FEM analysis of the raptures in the GINA profile;
- Strength calculations of the habitat;
- Shop drawings of the habitat;
- Flowchart for the execution of the installation and removal of the habitat.
