Definitions

  • compartment liner conceptINliquid bulk carrying vessels as expressed in the prior art is well known, compartment liners and buffer zones have been inc orperated into modern tanker vessels in an effort to. avert the tremendous damage that floating oil spills cause, however the bulk liquid carrying vessel industry has come under increasing pressure to creat safer methods to transport bulk liquids across open seas.
  • Compartment liners and buffer zones are vulnerable to puncture and tareing in the event of grounding or collision by steel being forced inward by external pressure.
  • Double hulled vessels have been sugested as a way to avert inboard steel hazard in the event of grounding or collision nbwever the ten to twelve foot void between, mulls is wasted space and renders the double null concept inefficenf, and yet they are still vulnerable to spills.
  • compartment liner concept is well known in the oil tanker industry, however the liners in most cases are composed of apoxy based fillament reinforced coating sprayed directly onto the walls of the vessel.

Abstract

Un chemisage (40) destiné à contenir un liquide situé dans un compartiment d'un navire, est protégé contre les déchirures ou les perforations par un tapis d'amortissement (12). Le tapis (12) se compose de sections réciproquement bloquées par l'intermédiaire de câbles (21). Chaque câble (21) est relié à un ressort à boudin (31) par l'intermédiaire d'une plaque de butée (42). Chaque ressort à boudin (31) est alors rattaché à une poutre d'ancrage latérale (15). Des plaques latérales pivotantes (81), qui soutiennent le chemisage (40), sont placées entre le chemisage (40) et le tapis (12).
