A method of installing a permanent vertical tethering element (30) between a floating structure (10) and an anchor means (20) said method comprising steps of: providing on said anchor means an upward opening guide funnel (108) located above a connector means (102) for connecting a lower end (118) of said permanent vertical tethering element to said anchor means; temporarily mooring said floating structure to said anchor means with a plurality of substantially vertical temporary mooring lines (18) held in tension by a buoyancy of said structure, while said floating structure is temporarily moored, lowering said permanent vertical tethering element from said floating structure until said lower end thereof is located a relatively short distance above said anchor means; observing, with an underwater television camera, a location of said lower end of said permanent vertical tethering element relative to said guide funnel of said anchor means; moving said lower end of said permanent vertical tethering element laterally as necessary to position it above said guide funnel; stabbing said lower end of said permanent vertical tethering element into said guide funnel; guiding, by means of said guide funnel, said lower end of said permanent vertical tethering element into engagement with said connector means; and connecting said lower end of said permanent vertical tethering element to said connector means.
