The EOSS is comprised of three basic parts:

The Users Guide

The Engineering Operational Procedures (EOP)

The Engineering Operational Casualty Control (EOCC)

EOSS USERS GUIDE.The Users Guide is a booklet which explains the EOSS package and how it is used to the ships best advantage. It contains document samples and explains how they are used. It provides recommendations for introducing the EOSS system and the methods for training the ships personnel in utilizing the pro-cedures set forth in this system.

EOSS documentation is developed using work-study techniques. All existing methods and procedures for plant operation and casualty con-trol procedures are documented, including the actual ship procedures as well as those procedures contained in available reference sources.

Each action taken is subjected to a critical examination to evaluate the adequacy of the present procedures. At the completion of this analysis phase new procedural steps are developed into an operational sequencing system, and step-by-step time-sequenced procedures and con-figuration diagrams are prepared to show the plant layout in relation to operational components.

The final step in the development phase of an EOSS is a validation on board ship check conducted to ensure technical accuracy and adequacy of the prepared sequencing system. All required corrections are made and then incorporated into the package before installation aboard ship.

The resulting sequencing system provides the best tailored operating and engineering operational casualty control procedures available pertaining to a particular ships propulsion plant.

Each level is provided with the information required to enable the engineering plant to respond to any demands placed upon it.
