A study of 2-stroke marine diesel engine characteristic based on condition based maintenance

In today’s environment, generating revenues for any industry is important. Profit margins are shrinking and often the difference between a profit and a loss can be as simple as preventing loss and improving efficiencies. Locating sources of energy waste, identifying failure conditions in electrical...

Marine engineering In today’s environment, generating revenues for any industry is important.
