  1. Le navire est surcharg\u00e9
    Ce type de dommage se produit souvent sur les ailes en caoutchouc plein, en particulier certaines vieilles ailes en caoutchouc plein, qui se fissurent souvent dans les parties faibles de la structure. Les fissures se trouvent g\u00e9n\u00e9ralement sur toute la longueur de l\u2019aile en caoutchouc solide. Les ailes en caoutchouc de type D et V sont plus courantes. La principale raison de la fissuration de la d\u00e9fense en caoutchouc est que l'\u00e9nergie cin\u00e9tique du navire heurtant la d\u00e9fense est trop importante, ce qui d\u00e9passe la charge que la d\u00e9fense en caoutchouc peut supporter. La raison de l'\u00e9nergie cin\u00e9tique d'impact excessive du navire est que la vitesse et l'angle d'accostage sont trop importants. Surtout lorsque l'angle d'accostage est grand, la proue entre en contact avec le quai et les d\u00e9fenses en caoutchouc avant le milieu de la coque, provoquant la concentration d'une forte \u00e9nergie cin\u00e9tique d'impact sur une ou plusieurs d\u00e9fenses, endommageant les d\u00e9fenses en caoutchouc. En plus des raisons ci-dessus, l'impact du navire est trop important, l'accostage des navires d\u00e9passant le type de navire et le tonnage con\u00e7us \u00e0 quai, et l'impact du vent et des vagues sur le navire.<\/li>\n\n\n\n
  2. Mauvais ancrage et connexion
    Cela s'est produit avec diverses ailes en caoutchouc plein. Les d\u00e9fenses en caoutchouc sont desserr\u00e9es, disloqu\u00e9es, tombant \u00e0 la mer et autres ph\u00e9nom\u00e8nes anormaux. La principale raison de ce ph\u00e9nom\u00e8ne est que l'\u00e9tat technique des boulons ou des cha\u00eenes qui fixent les ailes en caoutchouc est mauvais ou que l'entretien n'est pas effectu\u00e9 \u00e0 temps. Les mat\u00e9riaux m\u00e9talliques tels que les boulons d'ancrage et les cha\u00eenes utilis\u00e9s pour fixer les d\u00e9fenses se corrodent rapidement dans l'environnement marin et sont difficiles \u00e0 remplacer, ce qui entra\u00eene une mauvaise fixation des d\u00e9fenses en caoutchouc et affecte s\u00e9rieusement l'utilisation normale des d\u00e9fenses. Certains boulons d'ancrage sont en cours de conception et, bien que les conditions de remplacement soient prises en compte, ils ne sont souvent pas id\u00e9aux en utilisation r\u00e9elle. Par exemple, les boulons d'ancrage des ailes en caoutchouc en forme de V prennent la forme de bo\u00eetes \u00e0 boulons int\u00e9gr\u00e9es. L'intention initiale de la conception \u00e9tait de faciliter l'entretien et le remplacement des boulons d'ancrage, mais en utilisation r\u00e9elle, ils n'ont pas pu \u00eatre remplac\u00e9s en raison de la corrosion du fer, de la d\u00e9formation des boulons, etc., ce qui a affect\u00e9 la qualit\u00e9 de fixation de l'aile en caoutchouc, provoquant la chute de l'aile. s'\u00e9teint et soit endommag\u00e9.<\/li>\n\n\n\n
  3. Dommages dus au frottement
    Se produit g\u00e9n\u00e9ralement avec des ailes fixes en forme de V et de D. Les d\u00e9fenses en caoutchouc sont principalement endommag\u00e9es par des chutes d'angle, des fissures, des rayures de surface, etc. La principale cause de ces dommages est une friction excessive entre la d\u00e9fense en caoutchouc et le navire. Lorsque le navire d\u00e9barque \u00e0 une vitesse tangentielle \u00e9lev\u00e9e, en raison d'un frottement excessif, la partie de contact entre la d\u00e9fense en caoutchouc et la coque est forc\u00e9e d'avancer avec le navire, provoquant le cisaillement et l'endommagement de la d\u00e9fense. De plus, lors des op\u00e9rations d'amarrage, le navire doit parfois avancer et reculer, ainsi que le navire oscille d'un c\u00f4t\u00e9 \u00e0 l'autre ou de haut en bas en raison des vagues et des courants. Dans ce cas, lorsque le coefficient de frottement entre le navire et la d\u00e9fense en caoutchouc est sup\u00e9rieur \u00e0 0,4 (par exemple, \u00eatre tir\u00e9 par la ligne d'amarrage si elle est trop tendue), des dommages \u00e0 la d\u00e9fense peuvent survenir.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-2418","post","type-post","status-publish","format-standard","hentry","category-news"],"yoast_head":"\nCauses Of Damage To Solid Rubber Fenders -
