Abstract

With the successive introduction of larger and faster ships, two components are needed: high-output propulsion engines and highly efficient engines. This requirement has been fulfilled with extensive research and studies of the engine manufacturers along with all kinds of feedback from the users. However, it appears that the engine safety margin has been sacrificed somewhat in the process of engine development to meet the above requirement.<BR>For example, abnormalities in combustion chamber-related components on high-output engines with large bore sizes are major concerns to be resolved. In addition electric power consumption on recent ships has increased with the delivery of lager ships. A large number of electrically operated control systems have been adopted on ships, and proper handling and maintenance of the electric feeding device have become increasingly important.<BR>In view of these concerns, marine engineers are making the utmost efforts to keep the ship's schedules, maintaining the safe operation of the engin plant. I would like to take this opportunity to explain how to cope with the unexpected abnormalities and introduce two cases of trouble shooting which I experienced on board.<BR>One problem is the abnormal wear of piston rings and cylinder liners, and the other is the malfunction of the generator and the electric feeling control system.<BR>Hopefully this report will serve as a useful reference for marine equipment manufacturers, marine engineers and the concerned parties. In addition we hope that the manufacturers will take our requests as direct feedback from the“engine room”and understand the circumstances pertaining to marine equipment operation.
