GUIDING APPARATUS FOR SUBSEA MODULES, A METHOD AND A FOUNDATION

摘要

The invention concerns an apparatus for guiding a module (2) onto a foundation (3), for a subsea plant for the production of power from currents in bodies of water. The foundation (3) includes an area adapted for being con­nected to the module (2). The module (2) is adapted for being placed on the foundation (3) from a surface based vessel by means of a winch. The apparatus includes at least two receiving elements (12) with respective locking apparatuses, situated at a joining area of the foundation (6). Guiding posts (13) are adapted to be lowered down into the receiving elements (12) to be secured to the receiving elements by means of the locking apparatuses, and the guiding wire extends be­tween the surface based vessel and the guiding posts (13). At least two guiding tunnels (16) are provided on the module in a distance adapted to the localisation of the receiving elements (12). The guiding tunnels (16) are furthermore adapted for threading of the guiding wires (14) therein and for entering onto the guiding posts. A conical pipe (17) is placed at the underside of the module for entering into the foundation, and this is adapted to mate with the conical pipe (17). A se­curing apparatus is provided for securing the module (2) to the foundation (3), and a lifting wire extends between the module and the winch secured to the sur­face based vessel for raising and lowering the module (2) between the surface based vessel and the foundation along the guiding wire (14).
