中文摘要 | 船鉑主機的重大事故不是一日造成的,主機的重大事故都有其潛在的因素-性能參數的變化[1]。本文針對MAN B&W S50MC系列單動、直流掃氣直接驅動低速柴油引擎於貨櫃船使用5年後產生氣缸套早期龜裂的重大故障,進行深入整合的分析探討。本測試船舶為1994年3月建造完成首航,感謝海運公司全力支援並提供完整由首航至今年(2002)共計8年,包括輪機摘要日誌、主機使用資料(M/E Service Data)或稱之過扭調查表(M/E Torque rich investigation)及參考資料如輪機維修保養報告、燃油加油紀錄、潤滑油及冷卻水化驗報告等。 本研究採用參數模糊法將主機紀錄中的重要參數,利用參數故障模糊隸屬度函數,得到各參數的故障模糊度,再利用層次分析法以確定各參數在故障診斷中所佔的權重,最後得到主機各缸綜合故障模糊隸屬度,確定出主機故障與時間的關係趨勢,並經實船驗證本模式完全適用於同型姊妹船的維修保養計劃。本研究後段提出對船舶設計、營運操作及維修保養等方面的綜合分析探討,期為本世紀船舶可靠性維修(Reliability Maintenance)奠定基礎[2]。 |
英文摘要 | Ship's engine faults are not caused by a short period but by a series latent reasons- the trend of performance parameters decrease. This paper focus on a severe engine cylinder liners crack problem for the MAN B&W S50MC single action, uni-flow scavenging, direct driving low speed diesel engine installed on container vesse' after 5 years service. The studied vessel was built and completed maiden voyage in March 1994. The shipping company supplied 8 years information of the subject vessel from launch till now. We deeply appreciated their full cooperation and kind help. The information included main engine service data, engine department abstract log, engine maintenance report, bunkering report, lubrication oil and cooling fresh water analysis report etc. This paper will use fuzzy parameter method to record the important machine parameters. First, we can solve the degree of membership functions of fault fuzzy parameters. Then, the weight of the fuzzy membership function can be obtained by the Analysis Hierarchy Process (AHP) with Matlab software. Finally, the result of synthetic fuzzy membership function of each cylinder can be used to find out the engine real faults and time relationship. In addition, such model analysis is suitable for the real ship and others sister ships maintenance programs. All the analysis results can be applied to the modern ship design, operation and maintenance procedures. Moreover, this approach will provide a fundamental for the shipping reliability maintenance this century. |
