At present, we have been studying on more effective and economical features of remote and automatic control systems in machineries based on the experiences on several vessels with automatic control systems, which belong to our company. For M.S. SANTIAGO MARU, ocean going ore-carrier, we adopted progressive automatic controlling and watching devices for the machineries. In this paper, the most remarkable features on the devices are dealt, one is the remote control system of main engine, that is called "one motion driving device", and the other is the centralized watching and data loggering installation for the machinery part.
