Swivel comprising a sealing arrangement

A method of mounting a sealing element in a peripheral groove of a swivel, the swivel comprising:

• an inner swivel member and an outer swivel member that is arranged rotatably around the inner swivel member, wherein the swivel members have respective fluid paths communicating with each other through an annular space at an interface between the swivel members;
• a sealing arrangement on a side of the annular space at the interface, the sealing arrangement comprising:
• a peripheral groove provided in the inner swivel member or the outer swivel member;
• and
• a sealing element received within the peripheral groove and arranged to statically seal against a first one of the swivel members inside the peripheral groove and to dynamically seal against a second one of the swivel members;
• wherein a surface inside the peripheral groove in the first one of the swivel members abutting the sealing element is a substantially L-shaped textured surface extending along at least a part of two inner surfaces of the peripheral groove, the substantially L-shaped textured surface having three-dimensional textural elements for making frictional contact with the sealing element;
• the method of mounting the sealing element in the peripheral groove comprising:
• inserting a sealing element within the peripheral groove, such that at least a part of one surface of the sealing element abuts one of the two adjoining substantially L-shaped textured surfaces and one adjoining surface of the sealing element abuts the other of the adjoining substantially L-shaped textured surfaces;
• and
• positioning a shim between the sealing element and an inner surface of the peripheral groove in the first one of the swivel members, wherein the shim forms an L-shape, and wherein a first leg of the substantially L-shaped textured surface extends along an inner side surface of the peripheral groove and wherein a second leg of the substantially L-shaped textured surface extends along a first part of a bottom surface of the peripheral groove, such that a second part of the bottom surface is non-textured and wherein the sealing element abuts both the first and second part of the bottom surface.
