In the previous reports, the authors investigated a setting method of "Oil Curtain" which is a new device proposed by the authors to prevent spilt oil diffusion. Through the past experiments, some problems on the setting workability were clarified. In this paper, some conditions required in the setting work are discussed and a practical method of setting and stowing the curtain is proposed. In addition, the practicability is examined through some experiments. The obtained results are summarized as follows. (1) Most of oil spills occur at the early stage after an accident when a single-hull tanker runs aground. Therefore, an effective countermeasure to prevent or reduce spilt oil diffusion should be taken in a few minutes just after the accident. (2) A proposed method, which the rolled curtain is mounted on a handrail around the hull and set by only releasing the fastening, is practical in the setting work, because the curtain can be set for about 1 minute. Furthermore, as the work can be carried out with only one hand, it is possible that safety in the work is ensured by holding worker's posture with another hand.
