摘要

A method of installing and tensioning a buoy (10) at a subsea anchoring location, the method comprises the following steps. A buoy (10) is floated over a subsea anchoring location. One or more tethers (T) are hung off the buoy (10) such that each tether (T) extends from the buoy (10) towards the subsea anchoring location. Each tether (T) is provided with a tensioning apparatus (16) at the buoy (10) for tensioning the tether. Each tether (T) is connected to the subsea anchoring location and tensioned with the tensioning apparatus (16), wherein the tensioned tether pivots about an articulated support (28, 30) on the buoy (10).
