INNER DRILLING RISER TIE-BACK CONNECTOR SEAL
An improved seal disposed at an interface of a main body of an inner drilling riser tie-back connector (ITBC) and a subsea wellhead (212) is provided. The seal (220) comprises a main body portion formed of a pair of opposed inwardly projecting fingers (306) having a saw-cut profile at their ends and...

| description | An improved seal disposed at an interface of a main body of an inner drilling riser tie-back connector (ITBC) and a subsea wellhead (212) is provided. The seal (220) comprises a main body portion formed of a pair of opposed inwardly projecting fingers (306) having a saw-cut profile at their ends and an outwardly projecting lever arm disposed adjacent to and at an outward angle to one of the opposed inwardly projecting fingers (306). Under loading the outwardly projecting lever arm imparts a bending moment to the seal, which enhances the seal (220) created between the ITBC (200) and the subsea wellhead (212) and reduces the torque required to disengage the internal tie-back connector Figure 3 |
