Marine hose status monitoring system

Abstract

Provided is a marine hose status monitoring system which makes it possible to more definitively and more quickly detect damage to the inner-surface layer of a hose body. The present invention involves: embedding a leakage detection member (8) so as to extend between a first inner-surface layer (4A) and a second inner-surface layer (4B) of a marine hose (1) obtained by connecting a connection fitting (2) to both end sections in the lengthwise direction of a hose body (3) constructed by layering an inner-surface layer (4), a reinforcing layer (5), and an outer-surface layer (7), in order from the inner-circumferential side; connecting a leakage detector (10) to the leakage detection member (8); and determining by using the leakage detector (10) that damage has occurred to the inner-surface layer (4) when a fluid (F) flowing through a fluid channel (1a) of the hose body (3) contacts the leakage detection member (8).

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.
