This article makes use of a new management concept, Engine Resource Management (ERM). We researched the prediction of the unsafe events caused by human factors on the basis of the analysis of human factors in engine room. To reduce input samples the principal component analysis was led into computation before using BP artificial neural network to establish model. After the training and establishing...
Support Vector Machine SVM is widely applied to fault diagnosis of machines. However, this classification method has some weaknesses. For example, it can not separate fuzzy information, particularly sensitive to the interference and the isolated points of the training samples. In view of the problems mentioned above, a random forest fuzzy SVM multi-classification algorithm (RFFSVM) has been put forward...
Since 2007, several 10000TEU container ships of COSCO have been put into operation. Compared with the general container ships, its size and power are unparalleled. Obviously, it is a giant in the sea! However, we must have a clear understanding that there are also many risks existing in such ships. Once these risks expose, it would be more serious than the general large container ships. Therefore,...
Support vector machine (SVM) is widely applied to fault diagnosis of machines. However, this classification method has some weaknesses. For example, it cannot separate fuzzy information, particularly sensitive to the interference and the isolated points of the training samples. Besides, it has great demand for memory in calculation. In view of the problems mentioned above, a binary tree-based fuzzy...
This article makes use of the new concept of analytic hierarchy process (AHP) and engineering resource management (ERM), by the way of consultation with relevant marine management experts in the form of questionnaires to construct comparative matrix, utilizing matrix theory to respectively calculate the numerical value of each human error and arrange them in sequence, to obtain the key factors of...
In this paper, a method is proposed to diagnose faults of marine main engine shaft. Since empirical studies show various faults of fuel oil system induces the variation of vibration signals, we propose to diagnose faults of marine main engine shaft using vibration signal from engine. The proposed method consists of three steps. First, a wavelet analysis method is used to characterize the power spectrum...
In this paper, a novel approach is proposed to diagnose faults of marine main engine cylinder cover. Considering vibration signal is highly related with various faults of cylinder cover, we propose to diagnose faults of marine main engine cylinder cover based on vibration signal from engine. First, a wavelet analysis method is used to characterize the power spectrum of the vibration signal. Next,...
This paper proposes a method to model the thermotechnical parameters for the HITACHI-MAN-B&W 6L80MC/MCE main engine, which is widely used in various modern container ships. The simulation model for the main engines under the stable working condition is established using filling-emptying algorithm. This model has been extensively validated by a set of computer programs. The comparison of the model...
