<p>A method of installing a structure (2) on a bed of a sea, estuary or river from a floating installation vessel (1) is described. In such a method a plurality of attachment piles (6) and corresponding installation rigs. (5) are attached to the structure (2) prior to deployment of the structure. In addition, respective umbilical control cables (7) are connected to the installation rigs (5) prior to deployment of the structure. The structure (2) is deployed from a floating vessel (1) to a bed of a sea, estuary or river, such that, when the structure is located on the bed, the umbilical control cables (7) do not support the structure or installation rigs. A single installation operation for each attachment pile is performed, in which operation an installation rig (5) is activated so as to install fully the corresponding attachment pile (6) in the bed, without removal of the umbilical control cable (7) or the installation rig (5) therefrom.</p> |
