Link Tank Floor Repairs to Repeat NDT Results

Start with the physical floor area that was actually repaired, not only the indication number that prompted the work. A repair may cover several findings, extend beyond one mapped point or replace material containing multiple original references. Preserve the relationship between the findings, approved work instruction and actual completed area. The closeout record should make it possible to identify what changed and which repeat examinations address that changed configuration.

The worksheet is an evidence map, not a repair design or authorization to return a tank to service. The responsible inspection, engineering and operations processes determine the work and required examination. Keep their actual records referenced. A report preparer should not choose repair dimensions, substitute methods or infer that a completed drawing symbol establishes acceptability. The useful output is a traceable relationship between the actual work and its supporting examination evidence.

API’s API 653 program page identifies the standard’s subject as tank inspection, repair, alteration and reconstruction. The public program description is not a substitute for the applicable standard, edition or project instructions. Record the actual basis specified for this tank and repair package. Do not assume that every tank, repair type or examination task has identical requirements because the same standard number appears in a general scope.

Keep the tank assessment, repair design and NDT procedure references distinct. They answer different questions and may be controlled by different responsible parties. An NDT report can support an assessment without independently establishing the repair design or final service decision. The closeout map should connect the actual documents and their effective revisions, including any change that alters the required area or examination sequence.

Identify the floor-map datum, orientation, plate numbering and actual drawing revision used during the inspection. A sketch viewed from inside the tank and another viewed from below can appear similar while reversing the relationship of features. Preserve the source convention rather than assuming north-up or a standard viewpoint. The recipient should be able to locate the repair from the tank’s actual reference features without interpreting an unlabeled image or guessing which direction the numbering runs.

If the original scan map and repair drawing use different plate labels, create a confirmed crosswalk. Keep both identifiers available for retrieval. Do not rename the original acquisition references merely to match the final drawing, because the native evidence may still use the earlier labels. A consistent link between the two representations is more reliable than an apparently clean map that breaks the relationship to the underlying examination records.

Preserve the actual meaning of the initial finding. A scanner indication, local thickness measurement, surface observation and weld examination result are different evidence types. Do not collapse them into one defect-depth column without a supported technical basis. Where local confirmation was performed, retain its physical location, method and reviewed values alongside the original screening reference. The closeout history should show how the repair decision used the evidence rather than replacing the earlier result with a later number.

Eddyfi’s tank-floor reporting application note describes combining map layers, indication lists and repair-design features in its own software. That product context illustrates useful relationships, not a capability of NDT Connect or proof of a tank’s condition. Retain the actual source map and analysis package. The worksheet records their reviewed links without analyzing native floor-scanner data or reproducing proprietary mapping functions.

Connect each repair identifier to the instruction that defined the work. Preserve the specified area, relevant drawing and actual revision, together with any approved change. Do not treat a preliminary marked-up map as the final repair instruction unless the responsible process identifies it that way. A repair symbol can communicate location while leaving the technical work undefined. The ledger should point to the actual controlled record that explains what was authorized.

Where the actual completed repair differs from the initial proposal, retain the supported change and its review. Do not adjust the drawing silently to match the final photograph. The reason and authority for the change may affect the required examination and the relationship to neighboring findings. The report preparer records that decision rather than deciding whether a larger, smaller or differently shaped repair is technically acceptable.

Record the physical work type actually performed. Removing and replacing a floor plate creates a different configuration from local repair within the existing plate. A patch or other repair feature has its own boundary and connection details. Do not use the same repaired status for every case without a reference explaining the actual work. The original plate identity may remain useful historically even when part or all of the material has been removed.

Preserve the relationship between retained material and new material where the repair crosses their interface. An examination of one connection does not automatically describe another edge or the retained surrounding floor. Keep the required tasks and their actual results separately identifiable. The closeout map can show one repair feature while the supporting table lists several examination records needed to explain its complete reviewed state.

For each original finding, record whether it lies within the completed repair, remains outside it or requires further correlation. Do not assume that a repair named after an indication covers every nearby item. Use the actual drawing and work records to establish the relationship. A map can visually suggest overlap while lacking the dimensions or references needed to support it. Preserve unresolved spatial questions until the responsible review confirms the boundaries.

Allow one repair to address several findings and one finding to relate to more than one work element when the actual record requires it. Keep those relationships explicit rather than forcing a one-to-one list. This prevents duplicate closure counts and helps the reviewer see whether any portion of the original concern remains outside the documented work. The worksheet records the physical relationship without deciding that every included finding is technically resolved.

Identify the actual condition of the repair when each examination occurred. A check before final completion, an examination of an intermediate stage and the final required examination may have different purposes. Preserve their dates, scope and source reports. Do not use an earlier satisfactory result as evidence for work performed afterward unless the responsible process explicitly establishes its relevance. The final closeout should show which evidence addresses the actual completed configuration.

Where several methods are required, retain their separate tasks and results. A completed surface examination does not automatically establish completion of another specified test or an unexamined connection. Use the actual project instruction to define the task list and the responsible disposition to define closure. The reporting worksheet should not invent a universal examination sequence or select a method because it is convenient to enter in the available table.

In a fictional tank-floor package, repair R12 is shown as complete on plate P6. The referenced repeat report covers only the north and east portions of the repair boundary under the actual work plan. A draft map colors the whole repair as examined. Review separates physical work completion from the documented examination extent and identifies the remaining task. The report retains the valid completed results while keeping the unsupported portion open.

The responsible team then determines the appropriate next action and supplies the resulting evidence. This example specifies no repair geometry, required method or acceptance criterion. It shows why a single colored symbol should not conceal different task states. A repair can be physically complete while its examination package remains incomplete, and the closeout map should communicate that condition accurately instead of treating the drawing as proof of every required result.

Where a repair approaches a seam, annular region, sump or other feature, retain the actual relationship needed to understand examination scope. Do not merge a nearby original seam into the repair boundary solely because they overlap on a small-scale drawing. Each required examination subject should remain identifiable. The relevant engineering and inspection records determine what the relationship means technically; the closeout table preserves the references and actual work evidence.

If access around an internal feature limits examination, state the affected portion rather than presenting a blanket complete status for the plate. A general note at the back of the dossier may be easy to miss when the map shows a closed item. Connect the limitation directly to the repair or task row so the recipient can understand the supported result without searching unrelated pages for an exception.

Review the original finding list after repair mapping is complete. Identify items outside repair boundaries and retain their actual assessment or follow-up status. A repair program can address selected areas without removing every reported condition. Do not delete the remaining findings from the final map to make the tank appear uniformly clear. Preserve the responsible decision and supporting evidence for each item that remains relevant to the final assessment.

A documented decision that no repair is required is different from a missing decision. Use the actual assessment reference and avoid creating an administrative closed label where technical review has not occurred. The map should distinguish repaired areas, assessed unchanged areas and unresolved items using the project’s defined legend. It should not imply that the reporting application determined acceptability or that the absence of a repair symbol means no finding existed.

Record the actual examination state and any later physical change relevant to the evidence. If coating, lining or another activity follows examination, keep the sequence identifiable. A photograph of the final surface may no longer show the original repair boundary or marking. Preserve the source references that establish what was examined before those features became less visible. Do not use a later presentation image as a substitute for the actual examination record.

Keep reinstatement and other maintenance-completion claims separate from NDT closeout. State them only where the responsible project records support them. A technician leaving the tank or a work order being scheduled does not establish completion of later tasks. The closeout dossier can point to those records while remaining precise about which statements concern examination evidence and which concern other confirmed work.

Identify which map is the original inspection record, which is the proposed repair layout and which describes the actual completed work. These may be separate files or controlled layers, but their purposes should remain clear. Do not distribute an obsolete proposal as the final condition map because it has the cleanest appearance. Keep superseded references available for history while clearly identifying the current handover version.

When a revision changes an item’s closeout status, identify the actual reason and source evidence. A newly received report, corrected location crosswalk and changed repair boundary are different causes. The recipient should be able to determine what changed without comparing every drawing symbol manually. The reporting workspace does not automatically distribute revised PDFs or collect recipient acknowledgments, so the project’s delivery process needs its own confirmed record.

The digital reporting workspace can organize the plate, repair and repeat-examination matrix with a concise conclusion. Import supported DOCX or XLSX tables after previewing them. It does not draw tank layouts, analyze native scanner files or attach examination photographs through the logo controls. Retain those files in the agreed external package and use clear text references to the actual map revision and report entries.

Use the equipment tracker for entered examination-equipment references and the procedure draft tool for proposed reporting responsibilities subject to review. The quote comparison tool can compare actual scopes that include closeout deliverables. The tank-floor scanner reporting guide helps define those deliverables before work, while this worksheet connects the evidence after the actual repairs and examinations.

Check that every item marked closed has a supported relationship to its actual work boundary and required evidence. A repair quantity or area total cannot replace that item-level review. Two overlapping repairs may cover less unique floor area than their dimensions suggest, and a large repair may address several findings without creating several separate physical work areas. Keep any reported quantities tied to their defined purpose rather than deriving them from the number of map symbols.

If commercial quantities are included, preserve their contractual meaning separately from technical closeout. The billing basis may concern installed material, weld length or another unit that differs from the examination population. Do not adjust technical boundaries to reconcile an invoice. The actual work records, approved measurement basis and commercial agreement should explain the quantity, while the closeout matrix remains focused on the evidence supporting each reviewed repair state.

Choose an original finding and follow it through the local confirmation, repair instruction, actual completed boundary and repeat-examination records. Confirm that the current map shows the same physical relationship and retains any limitation. Then review one unchanged or unresolved finding to ensure it has not disappeared. This two-direction check tests whether the final dossier represents the complete decision history instead of only the repairs that produced convenient closed rows.

Replace the fictional worksheet example with actual records and use the report buyer-review guide for broader delivery checks. A useful floor-repair closeout map explains what changed, what was examined and what the responsible review concluded. It does not imply that a repair drawing, an issued PDF or a free reporting tool independently establishes tank fitness, compliance or authorization to resume service.
