Chapter 2—ADMINISTRATION, SUPERVISION, AND TRAININGMaterial Inspections madeby the BoardThe inspection made by the Board of Inspec-tion and Survey is in several respects similar tothe material inspection that has just been dis-cussed. In fact, the Board of Inspection andSurvey’s inspection procedures, condition sheets,and reports are used as guidelines in establishingdirectives for the material inspection. The primarydifference, in regard to material inspections, isthat the material inspection is conducted by ForcesAfloat, usually a sister ship, and the Board ofInspection and Survey inspection is conducted bya specially appointed board. This distinction,however, refers only to routine shipboard materialinspection. It must be remembered that the Boardof Inspection and Survey conducts other types ofinspections.Inspections of ships are conducted by theBoard of Inspection and Survey, when directedby CNO, to determine their material condition.Their inspection usually takes place 4 to 6 monthsprior to regular overhaul. Whenever practicable,such inspections are held sufficiently in advanceof a regular overhaul of the ship so as to includein the overhaul all the work recommended by theBoard following the inspection. Upon the com-pletion of its inspection, the Board reports thegeneral condition of the ship and its suitabilityfor further naval service, together with a list ofthe repairs, alterations, and design changes which,in its opinion, should be made.Acceptance Trials and InspectionsTrials and inspections are conducted by theBoard of Inspection and Survey on all ships priorto final acceptance for naval service, to determinewhether or not the contract and authorizedchanges there to have been satisfactorily fulfilled.The builder’s trials and acceptance trials areusually conducted before a new ship is placed incommission. After commissioning, a final con-tract trial is held. Similar inspections are madeon ships that have been converted to other types.All material, performance, and design defects anddeficiencies found, either during the trials or asa result of examination at the completion of trials,are reported by the Board, together with itsrecommendations as to the responsibility forcorrection of defects and deficiencies. The Boardalso recommends any changes in design which itbelieves should be made on the ship itself or otherships of its type. These recommendations aremade to the Secretary of the Navy.Unless war circumstances prevent it, anacceptance trial takes place at sea over anestablished trial course. The tests include fullpower runs ahead and astern, quick reverse, boileroverload, steering, and anchor engine tests.During the trial, usually the builder’s personneloperate the ship and its machinery. Ship’s per-sonnel who are on board to observe the trialcarefully inspect the operation and material con-dition of machinery and equipment. They noteall defects or deficiencies and bring them to theattention of the division or engineer officer, sothat each item can be discussed with theappropriate members of the Board of Inspectionand Survey.Survey of ShipsSurvey of a ship is conducted by the Boardof Inspection and Survey whenever a ship isdeemed by CNO to be unfit for further service,because of material condition or obsolescence.The Board after a thorough inspection, rendersan opinion to the Secretary of the Navy as towhether the ship is fit for further naval service,or can be made so without excessive cost.When the Board believes that the ship isunfit for further naval service, the Board makesappropriate recommendations as to the ship’sdisposition.SHIP TRIALSThere are a number of different types of trialswhich are carried out under specified conditions.A list comprising most of them is given here:1. Builder’s trial.2. Acceptance trials.3. Final contract trials.4. Post repair trials.5. Laying up or pre-overhaul trial.6. Recommissioning trials.7. Standardization trials.8. Tactical trials.9. Full power trials.10. Economy trials.2-49
