Buoyant apparatus for e.g. ship, has shell with reinforcement which is sized for housing anti-impact lining, and base combining with shell to form assembly with continuous outer surface, where lining has skin and structural part

摘要

#CMT# #/CMT# The apparatus has a shell (C) with a base part comprising reinforcement (R) of constant depth. The reinforcement is sized for housing an anti-impact lining (G). The shell and the base combine to form an assembly with a continuous outer surface. The lining has a skin (1) with a doubler at the exterior and a structural part (2) which is composed of a mesh of elastic material with high deformation. #CMT#USE : #/CMT# Used for ships, coaster ship, landing craft and compound ship, subjected to front collision with the ground and risk of cracking of base during approach of shore or shallow water. #CMT#ADVANTAGE : #/CMT# The lining resists the static and dynamic forces which can be exerted on the ship in all the authorized usage conditions, without causing unacceptable deformation and/or loss of tightness or does not compromise the operating safety of the apparatus. The skin of the lining ensures the sealing, resistance to abrasion and tearing, and the structural part ensures dampening of the impacts, while limiting the permanent deformation on the shell in case of collision, and permits to avoid hindrance to the performance of the ship. The structural part permits to absorb high displacements of foreign bodies as well as energy of heave and surge of ship on the base, caused by swell, bar effect or sea comber. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a transversal sectional view of a ship. C : Shell G : Anti-impact lining R : Reinforcement 1 : Skin 2 : Structural part #CMT#POLYMERS : #/CMT# The structural part is selected from a group constituted of polyurethane foam and rubber foam. The doubler is made up of aramid fiber and/or polyester.
