Abstract
A fluid swivel arrangement comprising a vertical stack of fluid swivels mounted on a turret of a weathervaning ship, enables a spare fluid swivel to be provided without requiring an additional pipe and consequent larger diameter of fluid swivels. A pair of fluid swivels (53, 54) are provided, with one serving as a spare to be used in the event of failure of the other. A single pipe (94) extends through holes (120) in the swivels and is coupled to the inlet ports (90, 92) of both swivels, so it can direct fluid into either one. A means for controlling flow, enables the flow to be switched to either fluid swivel. The means for controlling flow can include a plug (140) for insertion into the inlet port of one of the swivels, to block the inflow of fluid thereat. The means for controlling flow can also include a valve (130) lying along the pipe between the upper and lower fluid swivels, so when the valve is closed fluid flows only to the lower fluid swivel.
