Abstract

Tensioning apparatus is provided for tensioning a tether T extending between a first structure (10, Fig 9) and second structure (F1-4, Fig 9). A support bracket 24 is provided for attaching the apparatus with respect to the first structure. A tether holding arrangement 26 is provided for securing the tether with respect to the apparatus. A pivotable articulating member having a tether receiving channel (36, Fig 14) therethrough is provided, the receiving channel having a longitudinal axis A-A substantially aligned with a tether departure axis. A support socket 30 is adapted to pivotably receive the pivotable articulating member such that movement of the tether departure axis away from alignment with the receiving channel longitudinal axis results in corresponding pivotal movement of the pivotable articulating member with respect to the socket. A method of installing a production buoy using such tensioning apparatus is also described.
