Condition Monitoring System for Marine Hose

Abstract

The present invention provides a state monitoring system for a marine hose capable of detecting damage to an inner surface layer of a hose main body more reliably and earlier. A leakage sensing member (8) is buried between a first inner surface layer (4A) and a second inner surface layer (4B) of a marine hose (1) and extended, and the marine hose (1) ) Connect the connecting metal piece (2) to both sides in the longitudinal direction of the hose main body (3) formed by laminating the inner surface layer (4), the reinforcement layer (5) and the outer surface layer (7) sequentially from the inner peripheral side. At the end, the leak sensor (10) is connected to the leak sensing member (8), and the fluid (F) flowing in the fluid flow path (1a) of the hose main body (3) contacts the leak sensing member (8) In the case of , it is judged by the leak sensor (10) that the inner surface layer (4) is damaged.

Description

technical field [0001] The present invention relates to a state monitoring system for a marine hose, and more specifically, to a state monitoring system for a marine hose capable of detecting damage to an inner surface layer of a hose body more reliably and earlier. Background technique [0002] Marine hoses are used to connect oil tankers and other facilities at sea to transport crude oil and the like. Marine hoses are used in various environments with different natural environments such as waves, wind, and tides, and these natural environments change constantly. For example, when a typhoon or the like approaches and the waves become high, larger external forces from various directions act on the marine hose. Along with this, various deformations such as stretching, bending, and torsion occur in marine hoses. If the external force acting on the marine hose is too large and the deformation increases, there is a risk of damage to the marine hose. Specifically, the inner su...

Problems solved by technology

In addition, if the leaked fluid is small, the degree of swelling of the conductive elastomer member is very small, so the generation of damage to the rubber layer on the inner surface cannot be grasped.

Therefore, in order to more reliably and earlier sense generation of damage to the inner rubber layer, there is room for improvement.
