The disabled tanker was broken into two parts due to rough waves and bow part of the ship drifted to the sea shore in the heavy oil leakage accident of Russian ship named Nakhodka January in 1997. The loaded heavy oil flew out of the bow section of the ship continuously and caused the biggest marine pollution in Japan. Approximately 6,250 kl heavy oil leaked out in this accident. If the technology for the recovery of the drifting bow part of disabled ship in rough waves had been available, the serious disaster would be prevented from occurring. This report is based on the research results of 5 year research project sponsored by the Ministry of Land, Infrastructure and Transport from 1998 to 2003. The direct motivation of starting the project is Nakhodka incident. The purpose of this project is to predict the drift motion of disabled ships in rough sea and to tow them safely in order to prevent the secondary disaster such as collision, explosion and strand. The Optimum Towing Support System (OTSS), which can estimate the drift motion, towline tension, maneuvering method during tow and towing power of tow boats, has been developed to provide with the Japan Coast Guard and salvage companies. Further, the computer program for predicting the drift course considering wave effect has been also developed to be provided with the Japan Coast Guard.
