| Research Abstract |
1.In 6 cruises of the LNG Carrier between Japan and the Middle East from 2002 to 2003, ship's ballast water was sampled on board.
1)Embarked ballast water was sampled at the departure in Japan.
2)Ballast water was sampled in the tank in the open ocean before the ballast water exchange.
3)Discharged ballast water was sampled in the open ocean at the exchange.
4)Embarked ballast water was sampled in the open ocean at the exchange.
5)Discharged ballast water was sampled at the embarking port in the Middle East.
6)Sediments and mud in the bottom of the tank were sampled on the back way to Japan.
2.Plankton, bacteria, and germs in ballast water and sediments were investigated.
3.Heavy medal in ballast water and sediments were chemically analyzed.
4.The motions of ballast water were numerically simulated by the computational fluid model and made with the experimental circulation ballast tank to clarify the characteristics of the ballast water exchange process.
5.Investigate and collected was information on the ballast water issues, management, and clarifies at the International Maritime Organization.
