in the engine room shows the time that control is takenby the engine room. Similarly, the last entry made byengine-room personnel shows when control is shifted tothe bridge. When the Bell Book is maintained by thebridge personnel, it is signed by the officer of the deck(OOD).Alterations or erasures are not permitted in the BellBook. An incorrect entry is corrected by drawing asingle line through the entry and recording the correctentry on the following line. Deleted entries are initialedby the EOOW, the OOD, or the watch supervisor, asappropriate.OPERATING RECORDS AND REPORTSEngineering operating records are used to ensureregular inspection of operating machinery and toprovide data for performance analysis. Operatingrecords do not replace frequent inspections of operatingmachinery by supervisory personnel nor do theynecessarily warn of impending casualties. Personnelwho maintain operating records must be properlytrained to correctly obtain, interpret, and record data,and to report any abnormal conditions.The type commander’s directives specify whichengineering operating records must be maintained andprescribe the forms to be used when no standard recordforms are available. The engineer officer may requireadditional operating records when he or she deems themnecessary.The operating records discussed in this chapter aregenerally retained on board for a period of 2 years, afterwhich they may be destroyed according to currentdisposal regulations. Completed records must be stowedso they will be properly preserved and can be easilylocated.Diesel Engine Operating RecordThe Diesel Engine Operating Record-All Ships,NAVSEA 9231/2 (figs. 1-1 and 1-2), is a daily recordmaintained for each operating diesel engine. In shipswith more than one main engine in the same engineroom, a separate record sheet is maintained for eachoperating engine.The watch supervisor enters the remarks and signsthe record for his or her watch. The petty officer incharge of the engine room or the senior enginemanchecks the accuracy of the record and signs the recordin the space provided on the back of the record. Anyunusual conditions noted in the record are immediatelyreported to the engineer officer, and the record is sent tothe engineer officer for approval.Fuel and Water AccountsThe maintenance of daily diesel fuel, lubricating oil,and water accounts is vital to the efficient operation ofthe engineering department. Forms and proceduresnecessary to account for fresh water and fuel aregenerally prescribed by the type commanders.The accounts tell the engineer officer the status ofthe ship’s liquid load and form the basis of engineeringreports submitted to higher authority.Ship and unit commanders must know the exactamount of burnable fuel on hand. When you computethe amount of burnable fuel on board, consider only thefuel in the service and storage tanks. All the fuel belowthe fuel suction line is considered not burnable.Fuel and Water ReportsThe Fuel and Water Report, NAVSEA 9255/9 (rev.2-80) (figs. 1-3 and 1-4), is a report submitted daily tothe commanding officer. This report indicates theamount of fuel oil and water on hand as of midnight, theprevious day. The Fuel and Water Report also includesthe previous day’s feed and potable water consumptionfigures and results of water tests. The original and onecopy are submitted to the OOD in sufficient time forsubmission to the commanding officer or command dutyofficer with the 1200 reports. The copy is retained bythe OOD.Monthly SummaryThe Monthly Summary of Fuel Inventory andSteaming Hours Report, CINCLANTFLT 3100-4, is acomprehensive monthly report of engineering data.These data are used to calculate the operating efficiencyand general performance of the ship’s engineering plant(see fig. 1-5). Requirements for this report are containedin fleet commander instructions. The engineer officerprepares the report, has the supply officer verify the fuelreceipt figures, and forwards it to the commandingofficer. The commanding officer approves the report andsends it directly to the fleet commander. One copy isretained on board in the files of the engineeringdepartment. An additional copy of the report may beprovided to the type commander.The Monthly Summary includes the ship’s fuelreceipts data, fuel consumption and steaming hoursnecessary to establish monthly financial obligations,1-3
