Abstract:
1. A laying ship for laying flexible undersea lines at sea, the ship having a hull with at least one girder and a deck including a cavity with a floor and having arranged therein a circular turntable and a motor-driven support and rotation device for said circular turntable, the carrier structure of said turntable having a floor incorporated in the hull girder and forming an integral portion of said hull girder, constituting a downward setback of a substantially circular portion of the deck, said turntable floor positioned within said cavity and constituting the top wall of the hull girder and performing a role that is similar to that of a deck plate in terms of the strength of said hull girder, said turntable floor being secured to additional reinforcing elements within the cavity that form integral portions of the hull girder such that the hull girder is capable of transferring a load constituted by at least said turntable and said support and rotary drive device, and is capable of providing stiffness required for supporting said load, the top face of said circular turntable not projecting beyond the level of the portion of the deck that is immediately juxtaposed laterally thereto, the periphery of said turntable coming level with said deck, said turntable being supported by and co-operating in rotation with elements of the support and rotation device within said cavity and fastened to the carrier structure of the hull of the ship, said rotary turntable presenting attachment elements on its top face and suitable for enabling flexible line winding supports of a flexible line storage and handling device to be reversibly attached thereto, said winding supports extending in a direction ZZ′ perpendicular to and above said plane of the deck of the ship, said attachment elements being distributed circularly and at different radial distances from the vertical central axis of rotation Z 1 Z 1 ′ of said turntable.
