  • Marine fenders are commonly used to protect infrastructure and vessels during the docking of a vessel and whilst the vessel remains docked.
  • the infrastructure which may (for example) be a jetty, a bulk goods terminal, a container terminal, a passenger terminal, a dolphin structure or similar, is typically provided with one or more marine fenders.
  • a vessel When a vessel docks it will typically impact on the fender(s), with the force and direction of the impact on a given fender varying depending on a number of factors such as the size and type of the vessel in question, the loading of the vessel, pilot skill, and weather or water conditions. Whilst docked a vessel will generally move about and continue to impact the fenders and/or maintain contact with the fenders and continue to bear against them. This movement may be due, for example, to tides, currents, winds, and/or the loading or unloading of cargo.
  • Marine fenders commonly have a facing assembly including a face element against which a vessel impacts or bears during docking and whilst docked, and one or more fender elements positioned between the face element and the infrastructure.

  • the information obtained from the analysis of the data could, in turn, be used in a wide variety of ways, such as in analysing berthing dynamics, assisting with future fender/wharf design, feeding into the revision of safe/acceptable berthing operations/procedures.
  • the data may be used to assist in forensic analysis of berthing accidents - e.g. for the purposes of analysing insurance claims.

Abstract

L'invention porte sur une défense d'accostage flottante (100) pour le montage sur une structure (108) et sur un ensemble de montage (110) pour une défense d'accostage flottante. La défense d'accostage flottante (100) comprend une unité de garniture (102) destinée à venir en appui contre un navire et un élément de défense élastique (104) pour absorber les forces sur l'unité de garniture (102). L'élément de défense (104) est monté entre l'unité de garniture (102) et la structure (108). Un ou plusieurs éléments de détection de charge sont positionnés de façon à mesurer des forces appliquées à l'unité de garniture (102) et à délivrer en sortie des données de force associées aux forces mesurées.
