A support ship “Yokosuka” for a 6500m deep research submersible is provided with many underwater acoustic instruments. To get full performances of such instrments, it was necessary to reduce the underwater radiation noise from “Yokosuka” herself to the sea. For this purpose, from her initial planning stage until the completion, the authors carried out a thorough noise control, taking the underwatet radiation noise to be the most impotant problem to be solved. As a result, the underwater radiation noise from “ Yokosuka” drastically reduced and cleared the target level which was set at the design stage, and the underwater acoustic instruments could develop their performances to their full extent.<BR>This paper introduces the method of noise control applied to “Yokosuka”.
