On ships that are not governed by EOSS, thewarming-up schedule is mandatory.SECURING SCHEDULESSecuring schedules for propulsion machinery andboilers are chronological checklists of key steps. Theyare used to secure the ship’s main engineering plantaccording to the general degree of readiness in effect.The respective steps may be scheduled relative to thetime orders are received to secure the engine room orboiler. The securing schedules should list the auxiliarymachinery to be used after securing the mainengineering plant. The securing schedule must beaccording to the type commander’s directives. Asecuring schedule overcomes the normal tendency tosecure machinery too quickly. Securing schedulesshould be used without regard for the experience of thepersonnel involved. The engineer officer examinescompleted securing schedules and disposes of themaccording to the type commander’s directives.Securing schedules are not required for shipsgovered by EOSS, but they are mandatory on all otherships.PERFORMANCE STANDARDSCNO and the type commanders require certainengineering trials and inspections to determine thatstandards are being met and to evaluate the operationalreadiness of ships of the type. CNO and the typecommanders determine the frequency of theengineering readiness trials and inspections.Engineering readiness trials include full-powertrials, fuel-economy trials, and basic engineeringcasualty control exercises (BECCES). BECCES servesthe same purpose as engineering operational casualtycontrol (EOCC) which will be discussed at the end ofthis chapter. Readiness inspections include theadministrative inspection, the material inspection, andthe operational readiness inspection.ENGINEERING READINESS TRIALSEngineering readiness trials (full-power andfuel-economy trials) are required by CNO andprescribed in Ship Exercises, FXP3, and in the typecommander’s directives, which contain specificrequirements for the exercises and trials. Thecommanding officer conducts these trials periodicallyaccording to those instructions. The type commander, acommander subordinate to the type commander, or thetask force commander may assign observers for theengineering trials. These observers will come fromanother ship of the same type whenever practical. Theremay be times when it is impractical to provide observersfrom another ship. In those cases, personnel from theship conducting the trial may act as observers subject tothe typecommander’s requirementsforself-observation of trials.The number of personnel assigned to observeengineering trials will vary according to the trial and thesize and type of ship being observed. The duties of theobserving party are usually as follows:. The chief observer will organize, instruct, andstation the observing party. He checks the ship’s draft,either at the beginning of the trial or before leaving port;supervises the performance of the engine-roomobservers; checks the taking of counter reading; rendersall decisions according to current directives; and checksand signs the trial report.l The assistant chief observer helps the chiefobserver as directed; supervises the performance of thefireroom observers; checks the taking of fuel oilsoundings and meter reading; and makes out the trialreport.l Assistant observers review fuel soundings andmeter readings, counter readings, the ship’s draft, andother data as may be required for the trial report.The following items should be accomplished orconsidered before starting the trial:. When requested by the observing party, the shipbeing observed provides a signaling system that willallow fuel soundings and the readings of counters andmeters to be taken simultaneously.. The ship being observed will furnish the chiefobserver with a written statement of the date of lastundocking, the authorized and actual settings of all mainmachinery speed-limiting devices and the status ofsafety device test and inspections. The ship’s draft, trim,and loading must conform to trial requirements. In casea minimum draft is not specified, the liquid loadingshould equal at least 75 percent of the full-load capacityat the beginning of the trial.. The chief observer determines draft and trimbefore and after the trial. He verifies the amount of fuelon board and corrects the amount to the time the trialbegins. He determines the full-power rpm required forthe displacement and injection temperature existing atthe start of the trial.4-6
