ABSTRACT:
An improved conduit seal is provided for the upper connector assembly (10) of a TLP where the upper end of a tether (14) is pivotally secured within the tether conduit (38) of a floating platform (12). The conduit seal includes an annular elastomeric seal (48) and a series of mounting blocks (52) bonded thereto. The tether mounts a CLB housing (24) which has an annular lip (74) with a continuous groove (80). Each of the mounting blocks is provided with a locking pin (84) which can be hydraulically driven into the groove (80) to lock the mounting blocks on the CLB housing, and confine the seal (48) relative to the CLB housing.
