摘要： A method of installing a production buoy at a subsea anchoring location comprises floating a production buoy over a subsea anchoring location; hanging at least a tether off the production buoy such that the or each tether extends from the production buoy towards the subsea anchoring location; and submerging the production buoy to a depth which allows connection of the or each tether to the subsea anchoring location. The step of securing the or each tether to the subsea anchoring location comprises tilting the production buoy to one side in order to submerge said one side at a deeper depth to secure a pair of tethers at the one side of the production buoy to corresponding subsea anchoring foundations at said one side of the production buoy, and then tilting the production buoy to the other side in order to secure a pair of tethers at the other side of the production buoy to corresponding subsea anchoring foundations at that other side of the production buoy.

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).

摘要： A method of forming a protection system and a protection system for a secondary conduit adapted to be coupled to a main conduit is disclosed. The main conduit and the secondary conduit are for installation below the sea surface. The method includes spooling onto a reel an elongate member in a first configuration for transportation and/or storage until such a time that it is ready to be deployed. The first configuration is a substantially planar configuration. The method also includes paying the elongate member out from the spool and causing or allowing the elongate member to adopt a second configuration and form the protection system for the secondary conduit. The second configuration is a substantially non-planar configuration. The elongate member is coupled to an external surface of the main conduit.
