Abstract (en)
[origin: WO03096072A1] The present invention provides a method for deploying and retrieving seafloor equipment including the steps of: providing a conveying means (200) with a fixed end and a free end (201); releasing said conveying means (200) into a body of water (210) from a vessel (220) until said free end (201) reaches, or is proximate to, a seafloor (230) of said body of water (210); dragging said conveying means (200) behind said vessel (220) at a controllable speed; slidably attaching said equipment (240) including a recovery module (241) and stopping means (242) to said conveying means (200), wherein said equipment, said recovery module and said stopping means are secured one to another by a connector (244); sliding said equipment (240) to the free end (201) of the conveying means (200), said equipment (240) being fixed in position on the seafloor (230) by said stopping means (242) once said stopping means reaches the seafloor; activating said recovery module (241) so as to allow said equipment (240) to ascend from the seafloor (230) to a surface of the water; and retrieving said equipment (240) from the surface of the water. Preferably the conveying means (200) is in the form of a cable.
