Japan Marine Science and Technology Center has been constructing for the development of the 11, 000m depth class ROV “KAIKO” system. The final sea trial of full depth diving carried out on March at Mariana Trench. The “KAIKO” went down to the 2m altitude from the bottom, and cruised the 10, 909m depth. But, the data communication link was interrupted. We thoroughly investigated the cause of the trouble by postponing the sea trial. We pinpointed the problem and were improved on the secondary cable. The sea trial were restarted in February 1995, and the “KAIKO” touched the bottom of the trench.
