A pipe connector (8) for establishing a remote connection between a riser pipe (12) and a subsea wellhead (10). The connector comprises a plurality of annular elements (40, 52, 54) interconnected by a differential thread system (58, 60) which facilitates making up and breaking the riser-wellhead connection from a drilling platform or other surface location without rotation of the riser or diver assist. The preferred embodiment also includes a provision for establishing a metal-to-metal seal (66) between the connector and the wellhead, and a guide assembly (16) to assure proper alignment of the connector with the wellhead prior to completing the connection. |
