STRUCTURE DE SUPPORT ET D'ANCRAGE D'ÉOLIENNE MARITIME DU TYPE EMBASE GRAVITAIRE ET PROCÉDÉ DE REMORQUAGE ET DÉPOSE EN MER
The invention relates to a method for transporting and installing an underwater structure on the seabed, said underwater structure being intended to support and anchor marine equipment and comprising a gravity base (1) including a first solid block or first hollow caisson (2) having an upper outer surface (2b) and a side outer surface (2a), said method comprising the steps of: a) towing the base (1) equipped with flotation elements, and subsequently b) lowering the base to the seabed, characterised in that: prior to step (a), a plurality of second caissons (3, 3-1, 3-2) are removably secured to at least part of the aforementioned outer surface; in step (a), the second caissons are at least partially emptied; in step (b), the second caissons are filled with more seawater; and, after step (b), the second caissons are detached and emptied, such that they float back up to the surface (10).
