Mega-Float is a ultra large floating structure, whose size can be several kilo-meters scale and planned to be used for city infrastructures, such as the airport, the heliport and the power plant, etc. and then expected to have ultra long durability over 100 years.
Mega-Float Research Union was established in 1995 for the realization and the research project is now going to overcome some difficulties.
In this project, titanium clad steel lining was adopted as the corrosion protection method for the splash zone of the around side wall, considering ultra long durability. Various techniques for the lining work, such as automatic titanium welder and the repair method for some type of damages of titanium clad steel lining, were developed and tested using the proto-type large-scale floating model (300m length, 60m width, and 2.0m height) which was constructed in a real sea area.
It was, from these results, confirmed that the titanium clad steel lining was a very useful corrosion protection method for Mega-Float.
