1When starting the tool, a security warning may pop notifying that the macros are disabled. All cells that are highlighted yellow are unlocked input cells where user can enter the available information. Green cells have default value that can be changed by user.General NotesCustomer, project and calculation information as well as revision, date, description, the originator (by), checker and approver details are only entered in Calculation Cover Sheet. This information will be automatically transferred to the header of all other pages of the document. When adding a sheet to the calculation, the user must give a name to it.Instruction sheet and template change history sheets will not be printed as part of the document.User should not change the names of key worksheets (Instructions, Calculation Cover Sheet, Calculation Checklist, Table of Contents, Basis Assumption Summary , Result Summary, Flare Stack Sizing and Grade Surface Temperature).The worksheets are protected by blank password. User shall maintain the sheets protected. The work book is protected with blank password.The objective of this user manual is to provide a step by step guide on how to use the tool. When starting the tool, a security warning may pop notifying that the macros are disabled. Press Enable Content button to enable the macros.Important Message: Proprietary Document

STEP 1: Read Instructions Sheet After reading this instruction, user can go to the Calculation Cover Sheet by clicking Go to Cover Sheet button on the top right side of the Instruction sheet and start filling out the general and calculation data.Be sure to read through all the instructions on how to use the tool.

STEP 2a: Calculation Cover Sheet Please Fill in all the Project and Customer Details.Fill in the Calculation Objective.State Any Assumptions and Basis used for this calculation.State Calculation Conclusions.Insert References to files/documents used.Fill in the Calculation Method.State other Software Used, their version and if they are validated.Fill in date, revision, description, the originator, checker and approver information.If user requires additional space beyond any provided cells in this sheet, it is to be entered in a new calculation sheet. This includes appendices as well. For basis, assumptions, results and conclusions, Basis Assumptions Summary and Results Summary worksheets are to be used. This sheet is required to be filled in as part of quality requirement.5To add text, just move the main image to the right. Be sure you move it back into position when you are done.

STEP 2b: Calculation Cover Sheet (Contd) Clicking on Go to Instruction button takes the user to the Instructions sheet.Electronic File Location is the path where the current file is saved on your computer. Click on Show Active Sheets button to show all the active sheets, which are to be printed. This macro will then update the document page numbering. Project File Location is the path of the project folder.Click on Show All Sheets button to show all the sheets including the ones that are not required to be printed. However, the page numbers will not be updated.

STEP 3: Add Calculation SheetsUser may add as many blank calculation sheets as needed. User can choose to insert a portrait or landscape orientation in letter size sheet or landscape sheet in 11x17.After adding all the required calculation sheets, user must update the page numbers by pressing Show Active button for printing purpose.Be sure to name the added calculation sheet, otherwise it will be deleted.7

STEP 4: Table of ContentsFill in the table of contents manually in the highlighted yellow cells.All this information is automatically transferred from the Calculation Cover Sheet to all subsequent worksheets. Do not try to change the cells manually.This sheet is printed by default. User has the option to check or uncheck the Print Sheet box at the top of the page.

STEP 5: Basis Assumption SummaryUser may create an additional Basis Assumption Summary Sheet if required to provide more information. User may fill in the detailed design basis and assumptions for the calculation in the highlighted yellow cells.Only the latest revision information is shown in this sheet.

STEP 6a: Vessel Heat Loss CalculationStart calculation by inputting Vessel Name (up to five vessels).

STEP 6b: Vessel Heat Loss Calculation Section 1Select Vessel Orientation and input Diameter, wall thickness and height/length. Select Head Type.Select Vessel Location. For buried Vessel, input depth from grade to centerline.Choose Insulation Type and input thickness.Input liquid level inside the vessel. Vessel LocationAbove Grade Vessel is above ground (exposed to ambient air);Buried Vessel is buried underground (exposed to soil, ice or snow)Underground Vessel sits inside a containment underground and there is air between vessel and containment.

STEP 6c: Vessel Heat Loss Calculation Section 2Input /Select information in YELLOW(or Green) cells. Depend on Vessel Location, inputs for air or soil will be hidden.

STEP 6d: Vessel Heat Loss Calculation Section 3No user action is required. STEP 6e: Vessel Heat Loss Calculation Section 3

Values of these green cells will be set by Macro when clicking Calculate button(s). Once calculation is converged, these are the final temperatures.

User has option to calculate manually (without using Macro buttons) by changing these numbers.

STEP 6f: Vessel Heat Loss Calculation Section 4Activate Macro button(s) to start calculation. Each button works only for the Vessel in the same column.

User can choose to include or exclude head heat loss to the overall vessel heat loss. Useful if vessel is partially indoors.Once calculation is converged, the text on the button will change to Solved

STEP 7a: Vessel Heat Loss Calculation Section 5 CooldownActivate Macro button(s) to start calculation1. User chooses which Vessel to run cooldown calculation.2. Input required information including initial temperature.Total Heat Loss/Gain for Entire Duration

STEP 7b: Vessel Heat Loss Calculation Section 5 CooldownVessel temperature (V-5) after running cooldown Heat Loss/Gain for the last step

STEP 8: Fill the Results Summary SheetUser may summarize the results of the calculation in this sheet. More Result Summary sheets can be added if required.

STEP 9: Fill the Calculation ChecklistThis is a quality requirement to check all the boxes for applicable items under calculations, checking records and revisions
