The EOP documentation is prepared for specifically defined operational stages. These are defined as Stages I, II, and III.

Stage I is considered as the total engineering plant level under the direct cognizance of the plant supervisor (EOOW). The officer coordinates the placing in operation and securing of all systems and components normally controlled by the various space supervisors. The EOOW also super-vises those functions which affect conditions external to the engineering plant such as jacking, testing, and spinning main engines. The EOP documentation assists you, the plant supervisor, in ensuring optimum plant operating efficiency, properly sequencing of events in each operational evolution, and the training of newly assigned personnel.

During a plant evolution, you will control and designate the operation of the following systems and components:

Systems that interconnect one or more engineering plant machinery spaces and the electrical system.

Major components such as boilers, main engines, and electrical generators.

Systems and components required to support the engineering plant or other ship functions such as distilling plants, air compressors, steam system to catapults, and thrust blocks which are placed in operation or secured in response to demand upon their services.

To assist you the plant supervisor with these operations, the EOP section provides you with the following documents:

Index pages listing each document in the Stage I station book by identification number and title.

Plant procedure charts (figure 2-19) pro-viding step-by-step procedures for each engineering plant evolution. (NOTE: At the time this publication was prepared for printing, EOSS diagrams illustrating specific equipment for which the Engineman is responsible were not available; the example used, in this section, however, il-lustrates the types of EOSS diagrams used regardless of equipment .)

Plant status boards (figure 2-20) providing a systematic display of the major systems and cross-connect valves as well as a graphic presentation of the major equipment in each machinery space. These boards are used to maintain a current plot of systems alignment and equipment operating status.
