基于维修规划的舰船船体腐蚀防护经济性分析

Cost effectiveness assessment of ship hull corrosion protection based on the maintenance plan

  • 摘要: 船体作为舰船的重要组成部分,由于所处海洋环境复杂、恶劣,腐蚀严重,经济损失巨大。针对船体腐蚀严重造成的经济损失以及采用防腐技术带来的经济效益难以评估的问题,通过基本内涵的界定,从舰船全寿期角度探讨船体腐蚀损失及防腐费用的计量方法。归纳现有的防腐方案,运用蒙特卡罗模拟方法对防腐方案的参数进行敏感性分析。在既定的舰船维修规划情况下,对防腐措施进行费效分析,从而有效提高舰船船体防腐费用的利用效益。

     

    Abstract: As an important part of the ship, the hull suffers from huge economic losses due to the complexity of the harsh marine environment. Since the economic loss caused by severe corrosion is often severe and the economic benefit of anti-corrosion technology is difficult to assess, this paper explains the basic connotation, discusses the corrosion damage from the perspective of the ship service life, and proposes certain measures to evaluate the cost of corrosion protection. Particularly, the present corrosion protection schemes are put forward with Monte Carlo simulation of the parameter sensitivity analysis method, and the established ship maintenance planning is considered. Also, cost effectiveness analysis is carried out on the corrosion protection measures and it improves the effectiveness of the corrosion protection cost for the analyzing tools.
