Safety Assessment Of The Main Engine System About International Cruise Ship Based On FSA

The concepts of cruise vacation have been on rise since the cruise company pursuing economic benefits. Currently, Chinese market is aimed at by international cruise company. With the particularly prevalence of Chinese cruise market, many domestic enterprises crack into the cruise industry. It is imperative to develop domestic cruise industry.The particularity of international luxury cruise ship determines the complexity of the main propulsion diesel engine system. The reliability of the main propulsion diesel engine system varies with the working mode, and its reliability will decline to the lowest level when the four main diesel engines work simultaneously. As the key unit of machinery space of international luxury cruise ship, the operation conditions of main propulsion diesel engine system have a direct impact on the safety of cruise ship, marine environment and human life. However, safety of the main propulsion diesel engine system of the international luxury cruise ship has not been studied yet in academic circle. Therefore, it is of great significance to study the safety assessment of the main propulsion diesel engine system.Based on the Man–Machinery–Environment–Management(MMEM) theory and within the framework of Formal Safety Assessment(FSA), this paper establishes the assessment index system of the main propulsion diesel engine system of international luxury cruise ship. Then the safety assessment mode is established by using expert analysis and the calculation process of Analytic Hierarchy Process(AHP) and comprehensive assessment of fuzzy mathematics. Finally, taking the "Chinese Taishan" as an example, the safety assessment model is verified and the risk control scheme is proposed based on the assessment results.Innovations of this paper lie in:(1) Establish the safety evaluation model of the main propulsion diesel engine system of the international luxury cruise ship;(2) Taking "Chinese Taishan" cruise as an example to verify the safety evaluation model;(3) Design computer-aided calculation system.
