Abstract:
A compact vibration control equipment (21) for preventing vibration of a pipe (13) set in the water effectively. A tubular body (22) covering the underwater pipe (13) is suspended from a buoy (25). A plurality of regulating members (23, 24) are projecting radially from the body. The body can turn to follow up the direction variation of water flow through the buoy.
