The Distilling Plant Operating Record is a daily record of the operation of the ships evaporators and their auxiliaries. Entries are made for each hour of the watch while the distilling plants are in operation. Different ships have different types of distilling plants, but all of the daily distilling plant operating records require practically the same data.

The information required by this record consists of the following:

1. Temperature, pressure, vacuum, flow, chemical analysis, and density data from various points in the distilling plant

2. Scaling record for each evaporator unit, which includes the date of the last scaling, the hours operated, and the quantity of distilled water produced

3. Starting, stopping, and total operating time of each evaporator and various auxiliary machinery parts, such as air ejector and pumps

4. Remarks concerning the operation and maintenance of the distilling plant for each watch of the day

You must make accurate entries in the Distilling Plant Operating Record! Accurate entries not only help predict troubles but, should abnormal operating conditions suddenly develop, aid in locating the sources of trouble.

For other recommended miscellaneous records, refer to NSTM, chapter 90.
