Abstract
Abstract A floating type anti-oil anti-impact anti-wave barrier includes structure for intercepting oil floating on the water, for mitigating an impact force exerted by a ship or the like, and for intercepting waves. The barrier can collect oil which has flowed out onto the sea to prevent the oil from dispersing, and the barrier can be protected from damage caused by a ship, by drift, by waves, etc.
