Patent ID: 7997829

Claim:
A coupling between a flowline and a structure, the coupling comprising: a housing with a tubular member having a first longitudinal centerline and two tubular portions, each tubular portion extending normally from the tubular member and having a second longitudinal centerline normal to the first centerline; a first cylindrical member disposed within the tubular member and rotatable relative to the tubular member about the first centerline, the first cylindrical member supporting the flowline, whereby the flowline is rotatable about the first centerline relative to the housing; and a second cylindrical member disposed within one tubular portion and a third cylindrical member disposed within the other tubular portion, the second and third cylindrical members immovable relative to the structure; wherein the housing and the first cylindrical member disposed therein are rotatable about the second centerline relative to the second and third cylindrical members, whereby the flowline is rotatable about the second centerline relative to the structure.
