Material Requisition – What Is Piping: All about Piping Engineering

For the completion of any Engineering Project, It is very important to exchange information among the different Engineering Disciplines for starting the work simultaneously. The documents or objects used for exchanging the information to help progress the project is called deliverables. This article will provide a list of common deliverables from various disciplines of an oil and gas project. What is Deliverable? A deliverable is a document that is prepared by one department and used by another department for the execution of a project. Some deliverables are dependent on other deliverables, so for preparation of dependent deliverables first needs to complete the interconnected deliverables. Co-ordination between departments Deliverables Prepared by Different Department Process Engineering Deliverables Process Flow Diagrams (PFD), Process Flow Scheme (PFS)Piping & Instrument Diagrams (P&ID)Line ListEquipment ListProcess Design CalculationsProcess & Operational Control DescriptionProcess Data Sheets for InstrumentationProcess Data Sheets for main EquipmentPerformance Test Procedure Static Equipment Department Mechanical Data Sheet (MDS)Equipment Installation PlanEquipment fabrication DrawingVendor Drawing for Review Rotating and Package Equipment Department Mechanical Data Sheet (MDS)Equipment Specification ListVendor Drawing with Detail Deliverables from Instrumentation Department Instrument Data SheetInstrument Hook-upSystem Block DiagramsControl Room and Control Building LayoutsInstrument Location DrawingsInstrument Cable RoutingInstrument Power and Utility RequirementsInstrument IndexRelief and Safety Device IndexAlarm and Trip ScheduleData Transfer Cable Tray LayoutsAir Distribution DiagramInstrument Junction Boxes and Panels Block Diagrams Electrical Department Grounding layoutsCable Tray Route LayoutsPlant and Buildings Lighting LayoutsSubstation Sizing and LayoutWiring Drawings and Terminal ConnectionsElectrical Equipment and Component Data SheetHeat Tracing Panel SchedulesLoad ListTray SizingEmergency Power Load Specification HVAC Department Air Handling Unit (AHU) LayoutDuct LayoutCooling/Chilled Water Piping Layout Civil and Structural Department Foundation and Structural LayoutsReinforced Concrete SpecificationSteel-work SpecificationFoundation Settlement DataProcedures for Earthworks like Excavation and LevelingFloor or Wall cut-out section LayoutDrawing of Platform, Ladders, Stair and Hand-railingRoad Layouts Fire Fighting and Safety Department Hazards Study ReportLayout Approval ReportP & ID for Fire Water PipingFire Fighting Equipment LayoutWater Storage Tank Data SheetOperating Manuals for Fire Fighting EquipmentExtinguishing System Design Deliverables of Piping Department Layout Overall Site Plot PlanArea Mark-upUnit Plot PlanZero-Level MTO (Material Take-off)Equipment LayoutGeneral Arrangement (GA) Key PlanPiping Layout (GAD)Piping StudyPipe Support LayoutNozzle Orientation DrawingPipe Rack Layout3D ModelConstruction IsometricIntermediate MTOVessel Trim Drawing and MTOVendor Drawing Review ReportFinal MTOWork Completion Tracking ReportAs-Built Drawing Material Materials Selection DataPipe Thickness CalculationMiter Bend and Reinforcement (RF) Pad CalculationPressure & Temperature (PT) Rating TablePiping Material Specification (PMS)Valve Data Sheet (VDS)Special Parts Data SheetVendor Drawing Review ReportCorrosion Study ReportMaterial Testing ReportPressure Test Procedure Stress Stress Critical Line ListStress Analysis SpecificationStress SketchesSupport Selection ListCAESAR Analysis ReportSupport DrawingSupport Span ListPiping Loop Calculation and LayoutDifferent Load Specification Sheet of SupportsFinal Stress Report Deliverables or Information Provided by Client Product ConceptOperating GuidelinesCodes and Standards as per LocationStatutory Requirement DetailsMetro-logical Data Users and Uses of Piping Deliverables Overall Plot Plan Used by all the departments including clients.For the Finalization of pipe rack, trenches, and underground facilities (Pipes/Cables).
