REFRIGERATION/AIR CONDITIONING EQUIPMENT RECORD

back of the record for the daily signature of the engineer officer. AIR COMPRESSOR OPERATING RECORD REFRIGERATION/AIR CONDITIONING EQUIPMENT RECORD The Refrigeration/Air Conditioning Equipment Operating Record, NAVSEA 9516/1 (fig. 2-7), is a complete daily record for each operating refrigeration plant and air conditioning plant (except package units). Spaces on the front of the record are for entries applicable to both refrigeration and air conditioning plants (view A of fig. 2-7). The entries made on the back of the record are illustrated in view B of figure 2-7 (air conditioning). Note that data are recorded at 2-hour intervals in this record. The A division officer reviews the contents and initials the record daily. GYROCOMPASS OPERATING RECORD The Gyrocompass Operating Record is a locally prepared, complete daily record for each operating master gyrocompass. The form for the log is prepared according to the type commander’s directives. Columns in the log should provide space for recording the times of starting and stopping the gyrocompass, total hours of operation since delivery of the gyrocompass, and important operating data pertaining to the gyrocompass installation, The petty officer in charge of the interior communications (IC) equipment checks the accuracy of the log and the electrical officer notes its contents daily. IC ROOM OPERATING RECORD The IC Room Operating Record is a daily record of major electrical equipment in operation in the IC room and is maintained by the IC watch. The form for the record is prepared locally according to the type commander’s directives. On small ships the gyrocompass log and the IC room record may be maintained on the same form. Important data such as voltages and currents of major units of IC equipment (IC switchboard, telephone switchboard, and motor generator sets) should be recorded on the form. The IC Room Operating Record is checked and approved in the manner described for the Gyrocompass Operating Record. Some large ships maintain an Air Compressor Operating Record that contains important data such as temperatures and pressures pertaining to air compressors in operation. When required by the type commander, the Air Compressor Operating Record is prepared locally according to his directives. Contents of the record should be checked by the petty officer in charge of the air compressors and the appropriate division officer. FUEL AND WATER ACCOUNTS The maintenance of daily fuel oil, lubricating oil, water, and diesel oil accounts is vital to the efficient operation of the engineering department. The type commander generally prescribes forms and procedures necessary to account for and preserve a limited supply of fresh water and fuel. Chapter 090 of the NSTM lists the fuel and water accounts that the Naval Sea Systems Command (NAVSEASYSCOM) considers indispensable to the engineering department. Principally, these accounts inform the engineer officer of the status of the ship’s liquid load. They also form the basis for several important reports submitted to higher authority by the engineer officer. One of the most important of these is the report of the amount of burnable fuel on hand. It is fundamental to all naval operations that all ship and unit commanders know the exact amount of burnable fuel on hand. It is sound engineering practice to fill all fuel oil tanks to 95 percent of volumetric capacity to allow for expansion and to prevent spillage. When submitting fuel reports, the 95 percent volumetric capacity of the tank is assumed to be 100 percent of the burnable fuel. It is possible, however, to fuel above the 95 percent volumetric capacity. When fueled to 100 percent volumetric capacity, the burnable fuel percentage figure will exceed 100 percent. The engineer officer should not hesitate to report burnable fuel in excess of 100 percent when this amount is actually on board. When computing the amount of burnable fuel on board, only the fuel oil in storage tanks and service tanks is considered and only if it is above the service suction and transfer suction tailpipes. Fuel below those pipes is not considered burnable. The design height of suction tailpipes is shown on ship’s plans. The fuel oil in contaminated tanks (settling or separating tanks), also is not considered burnable. 2-14
