CHAPTER 11

DIESEL ENGINE OPERATING PRACTICES

In this chapter we will apply the material in the preceding chapters to the practical problems of operating diesel engines. Since the diesel engines used by the Navy differ widely in design, size, and application, the procedures we will discuss apply only to general types of installations. Descriptions will apply generally to the various auxiliary and propulsion diesel installations in Navy ships. Detailed and specific information and operating instructions are provided in the manufacturers manuals for specific installations, in NAVSEA technical manuals, and in ships doctrine such as the Engineering Operational Sequencing System (EOSS).

After studying the information in this chapter, you should understand the purpose of EOSS and its value in contributing to effective engineering plant operations and casualty control. You should also be able to recognize the fundamental starting, operating, and stopping procedures for a diesel engine under normal operating conditions.

ENGINEERING OPERATIONAL SEQUENCING SYSTEM (EOSS)

Each new class of ship that joins the Navy is more technically advanced and complex than the one before. This means that there is a need for more and better training of personnel who must keep the Navys ships combat ready. The need for training and the problem of frequent turnover of trained personnel require the type of system that can be used to keep things going smoothly during the confusion of a casualty. The EOSS was developed for that purpose.

The EOSS is a set of procedures and diagrams designed to eliminate problems because of operator error whenever personnel are aligning piping systems or starting and stopping the machinery. The EOSS involves the participation of all personnel from the department head to the fireman on watch. The EOSS consists of detailed written procedures, with charts and diagrams, which were developed for safe operation and casualty control of a specific ships engineering plant. The EOSS improves the operational readiness of the ships engineering plant by providing positive control of the plant. This, in turn, reduces operational casualties and extends machinery life.

The EOSS is divided into two subsystems: (1) Engineering Operational Procedures (EOPs) and (2) Engineering Operational Casualty Control (EOCC).
