Since the floating structure is designed
to have enough strength to the collision of the largest ship passing
around the floating structure, the damage by the collision is limited
at the local area not to cause such further damage as the floating
structure sinking or drifting. The example of the investigation on the collision of a ship is as follows:
Size of the ship ---- 80,000 DWT
Speed ---- 12 knots
Direction ---- Right angle
<Result> ---- Limited local damage
