The Marine Engineer, who is responsible for the engine room shift, is responsible for constantly monitoring and controlling the status of all systems, operating or not, as described in figure below. On an automation certified ship, command and control elements must transmit, apply, receive and display data working according to an algorithm accurately and precisely.

A typical temperature operating between min and max limits

 

Here, t1 is the time when the Ship Engineer takes over the shift. t2 is when the OOW observes a steady increase in temperature. The OOW decides that the temperature is constantly increasing but still within limits. If the data shown in the chart is for the exhaust temperature of a diesel machine, OOW considers it normal. However, if OOW knows how to do graphical analysis, it can calculate in how many minutes the temperature will reach the maximum limit.
