Nothing contained in any Rule, Guide, standard, certificate or report issued by the Bureaushall be deemed to relieve any other entity of its duty or responsibility to comply with all applicablelaws, including those related to the environment.1.21 Classification Symbols1.21.4 Transfer from Other Recognized Classification Societies (2002)(New paragraph 1.21.4 is added and the current 1.21.4 is renumbered 1.21.5.)The Committee will consider hull, equipment or machinery built to the satisfaction of the Surveyorsof the Bureau in accordance with plans that have been approved to the Rules of another recognizedclassification society with verification of compliance by the Bureau. Such consideration will beconducted per 1-1-4/3.5 of the Rules for Building and Classing Steel Vessels.1.29 Submission of Plans, Calculations and Data(Introduced the groupings a, b, c and d with titles in 1.29.2 and expanded list ofplans and calculations in 1.29.3 to be submitted.)1.29.2 Documentation to be Submitted (2002)The plans and details required for review and approval are as follows and are to be submitted asapplicable to the particular design features and/or systems:Notice No. 3 – January 20022ABS RULES FOR BUILDING AND CLASSING UNDERWATER VEHICLES, SYSTEMS AND HYBERBARIC FACILITIES . 1990a Design and Operational ParametersDesign pressures and depthsDesign temperaturesHydrostatic test pressuresDesign sea state conditionsMaximum operating depthMaximum mission timeMaximum number of occupants in each unit and/or systemMaximum weight of units including occupants, contents, entrapped water, etc.b GeneralGeneral arrangementCross-section assemblyOutboard profileMaterial specifications and grades, including tensile and impact values, for all pressureretaining or load bearing itemsDimensional details of pressure hull, pressure vessel(s) and scantlingsWeld details of pressure hull, pressure vessel(s) and scantlingsWelding procedures to include base and filler materials, pre and post weld heat treatment,tensile and impact values, extent of nondestructive testing.Out-of-roundness tolerancesFabrication tolerancesDimensional details of penetrators, hatch details, hatch rings, lugs and any other internal orexternal connection to the hullPenetrator sealing arrangementsHatch sealing arrangementsNameplate, including nameplate material and method of attachmentPlan showing all hull valves, fittings and penetrationsExostructure detailsDimensional details of viewport componentsHard ballast tanks design detailsSoft ballast tanks design detailsPiping systems including pump capacities and pressure relief devicesBallast piping systemsLayout of control standsEquipment foundation and support arrangements with details where such foundations andsupports increase stresses in the pressure hull or experience significant stress due to theoperating loads encounteredRelease devices and arrangement for jettisonable weights and equipmentNotice No. 3 – January 2002ABS RULES FOR BUILDING AND CLASSING UNDERWATER VEHICLES, SYSTEMS AND HYBERBARIC FACILITIES . 19903Propeller details including shafting, bearings and sealsPropulsion motors, thrusters and wiring diagramSteering control systemElectrical distribution systemBattery capacity, arrangement and main feeder schemeLifting and handling systemDepth indicating systemsEmergency systemsFire fighting systemDetails for permanently installed pressure vesselsDocumentation for portable pressure vessels including standards of construction and designcalculations for external pressure if units may at any time be subject to this condition.List and location of implodable volumesMaterials and dimensions of umbilicals including cross sectional detailsAny additional system deemed necessary to the intended operationsc Life Support Systems and EquipmentLife support system details, both normal and emergencyLife support system capacities, fluids contained and supply arrangementSpecifications for environmental control systems and equipment including heating, gasanalysis (CO2, CO, CH4, O2, etc), absorption, circulation, temperature control, humiditycontrol, equipment for tracing contaminantsComponent list including manufacturer, model, design specifications and test documentationfor all equipment used in the life support systemFor gas analyzers: specifications of type of gas to be detected, principle of detection, range ofpressures under which the instrument may be usedLodging facilities and drainage systems in hyperbaric chambersd ProceduresProcedures for out-of-roundness and sphericity measurementsCleaning procedures for breathing gas systemsInclining experiment proceduresFunctional test proceduresSea trial procedures for normal and emergency condition tests1.29.3 Calculations (2002)The following calculations and analyses are to be submitted for review:Pressure vessel stress analysis in compliance with Section 6Foundation stress analysisPressure hull support reaction analysisAnalysis of lifting load and stresses induced in the hullNotice No. 3 – January 20024ABS RULES FOR BUILDING AND CLASSING UNDERWATER VEHICLES, SYSTEMS AND HYBERBARIC FACILITIES . 1990Window calculations in compliance with Section 7Life support system analysisHeat/cooling consumption for the hyperbaric chamber or underwater vehicle under the designconditions and the expected environmental temperaturesElectrical load analysis and loss of power, power sources; power demandsShort circuit current calculationsCoordination of short circuit protection devices (coordination study)Calculation for the center of gravity and center of buoyancyIntact stability analysisDamage stability
