A ship’s hull is constantly moving, with vibration from the engines, pitching and rolling due to waves, all resulting in twisting and distorting. Tanks also repeatedly shrink and expand because of the temperature and pressure of the cargo. Furthermore, the liquid surface inside the tank generates sloshing due to the ship’s movements, repeatedly adding force onto internal pipes and equipment. “Marine tanks” must endure harsh conditions incomparable to tanks located on land.
With the ship’s hull constantly pitching and rolling, and tanks repeatedly shrinking and expanding, one would think one would want to firmly fix tanks and their internal structures, as well as pipes in loading/unloading plants, but a firm structure with increased strength would only result in damage. The question is how to combine strength and flexibility, and realize a flexible structure overall. This is where our expertise built up over many years lies.
