摘要： A method for replacing an outer annular ring of a fluid swivel includes a swivel comprising an inner annular ring and an outer annular ring, the rings being located with their adjacent cylindrical surfaces in close proximity for defining a chamber, for receiving a fluid, between peripheral opposing faces of the inner annular ring and the outer annular ring, wherein the inner annular ring is adapted to be connected to an end of a fluid line and wherein the outer annular ring is adapted to be connected to a product piping on the vessel, wherein the method comprises the steps of: removing the outer annular ring, replacing the outer annular ring by means of a first semi-circular element and a second semi-circular element, and fixing the first semi-circular element to the second semi-circular element, by means of a fixing means, to form a replacement outer annular ring of the swivel.
