A dynamic surface buoy assembly, for maintaining an umbilical of an ROV (Fig 4) in a vertical orientation extending vertically from the ROV to the surface of a body of water within which the ROV is carrying out inspection operations, including a buoy body 1, a floating ball 7 and a self-unhooking device 9. The buoy body has a U-shaped opening, a clamping groove, the shape of which matches the shape of the floating ball, formed in the underside of the U-shaped opening, and a limiting portion arranged on an upper part of the clamping groove for preventing the floating ball from moving upwards or downwards in relation to the buoy body while allowing the floating ball to move back and forth inside the buoy body. The buoy body is connected to the floating ball through a cable, with a centre of the floating ball having a through-hole structure configured to allow the umbilical cable to pass from the ROV to a shore station (Fig 4).
