Oil pollution caused by tanker accidents is increasingly becoming a serious public issue. Even if a large quantity of oil spills from the tanker, there are no effective countermeasures that seamen can take by themselves. Most oil spills occur at the early stage after the accident. In addition, no other support can be expected just after the accident because rough weather conditions often continue for several days, preventing spill control operations. Therefore, some effective devices which can be operated by seamen themselves should be boarded. In this paper, the authors propose a new device to prevent tanker-spilt oil diffusion. It encloses a hull with curtains whose depth is nearly equal to the full load draft of the ship, and sinkers are mounted on the foot of the curtain to be stabilized in water. Through some two-dimensional model experiments, it is shown that the device performs better than an oil boom in preventing or reducing tanker-split oil diffusion. Furthermore, it becomes clear on the basis of a full-scale performance of a curtain that one of the most practical setting method of the device is to handle the curtain rolled in the shape of a rope.
