Abstract: 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.

Abstract: Method for replacing an outer annular ring a fluid swivel (1), the fluid swivel being adapted to allow fluid transfer across a rotary interface between the end of a fluid line connected to the seabed and product piping on a vessel for gas and oil production, wherein the swivel (1) comprises an inner annular ring (3) and an outer annular ring, the rings being located with their adjacent cylindrical surfaces in close proximity for defining a chamber (2), for receiving a fluid, between the peripheral opposing faces of the inner annular ring and the outer annular ring, wherein the inner annular ring (3) is adapted to be connected to the end of the fluid line and wherein the outer annular ring is adapted to be connected to the 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 (10) and a second semi-circular element (20), and fixing the first semi-circular element (10) to the second sem
