Unmanned Machinery Spaces (UMS) Ships —
Control and Alarm Requirements
The number of UMS ships has increased rapidly over the past few years. Control systems are much more reliable now than they were when first applied to ships. Educating the crew to understand control functions is now undertaken by most shipowners. More ships will, in future, be fitted with remote-control systems as a means of reducing crews.
Nowadays, however, far more UMS ships are in operation. Crews have grown familiar with the systems and training is more prolific. In the immediate future more owners will adopt UMS, not only as a means of cutting crew to a minimum and thus cut operational costs, but also for reasons of safety.
Remote-controf systems. As a number of remote-control stations may be installed, operation must only be possible for one station at a time. There should he no misunderstanding as to which station has control at any time one time, thus there should be continuous indication at all the main control stations showing which one has control. When control is transferred from on'e station to another, a warning must be given. Only one-station which has taken control must acknowledge the fact.
There must be means by which the propulsion machinery can be stopped from the bridge, regardless of whether another station is being operated. Any orders activated from the bridge are to be indicated in the control rooms.
