Thermotechnical tests of an electronically controlled main high-speed engine of a marine vessel

Abstract

Abstract Thermotechnical tests of the main engine after a malfunction for putting it back into operation under the supervision of the Register inspector are presented in the paper. The electronically controlled high-speed Caterpillar C32 engine on the port side with an output of 1000 kW is described.Experimental studies of the value influence of thermaland vibration parameters on changes in the engine technical state are carried out during thermotechnicaltests. The experimental research methodology includes a classical approach to conducting such tests and a contemporary method with remote data transmission to the office of the vessel owner’s company.The accumulated practice in conducting experimental studies of the technical condition control by the in-place repair method of diagnostics makes it possible to move from classical approaches of technical operation to new ones included in the remote control and monitoring system of vessel technical means of autonomous ships in operation.The conducted studies have shown that the obtained values of the thermal engineering and vibration parameters do not exceed the maximum permissible values specified by the manufacturer.The results of the experimental study of Caterpillar engines demonstrate the defect initiation in one of the engine mounts by exceeding the values of vibration velocity.The conducted experimental studies of vessel technical equipment by the in-place repair method of diagnostics of marine vessels in operation are the basis of the control system of autonomous ships.
