  • Hull device
    Patent number: 11634199
    Abstract: Disclosed is a hull device designed to be reversibly attached to an outer surface of a ferromagnetic structure of a marine or submarine system or vessel. The device includes at least one attachment surface suitable for attaching the device to the structure, and a plurality of permanent magnets arranged in the vicinity of the attachment surface in order to attach the device to the structure.
    Type: Grant

  • Method for determining the magnetisation of the hull of a ship, and associated device
    Patent number: 9568562
    Abstract: A method of taking a plurality of measurements of the magnetic field using the plurality of sensors; includes assessing the inductive magnetic excitation; and determining the likely distribution of magnetic sources on the surface of the hull by resolving a system of equations derived from modeling the physical phenomena at play, on the basis of the plurality of measurements taken and the assessed inductive magnetic excitation. The model describes the induced magnetic sources as a distribution of dipolar sources and the remanent magnetic sources as a distribution of monopolar sources. A device (6) for determining the magnetization of the hull of a ship for implementing the method is also described.
