TANK ROOF PLAN

SCALE: 3/32" = 1'-0" (VERIFY ALL DIMENSIONS WITH EXISTING CONDITIONS)

TANK BOTTOM PLAN

SCALE: 3/32" = 1'-0"

TANK REPAIR NOTES:

1. AFTER REMOVAL OF COATINGS THE CONDITION OF THE FOLLOWING ELEMENTS

SHALL BE REVIEWED BY THE E.O.R.. IF EXTENSIVE SECTION LOSS IS

OBSERVED, SEE REPAIR DETAILS:

· TANK SHELL SEE 1/S-3

· TANK SHELL BOTTOM SEE 2/S-3

· TANK BOTTOM SEE 3/S-3

· TANK ROOF PLATE SEE 5/S-3

· RAFTER TO SHELL CONN. SEE 6/S-3

· TANK RAFTERS SEE 7/S-3

2. SEE 9/S-3 FOR SEALANT AT RAFTER TO ROOF PLATE, ADD ALTERNATE BID ITEM.

3. SECTION LOSS AT SHELL JOINT WELDS SHALL BE REMOVAL AND

REPLACEMENT OF WELD MATERIAL.

4. FOR PERMISSIBLE SWEEP IN RAFTERS, SEE 4/S-3. ADD SUPPLEMENTARY

RAFTERS AS REQUIRED AT LOCATIONS WHERE SWEEP EXCEEDS THE

ALLOWABLE. SEE 6/S-3 AND 8/S-3 FOR RAFTER REPLACEMENT ATTACHMENTS.

MINIMUM PLATE THICKNESS - FOR REFERENCE:

ULTRASONIC TESTING OF PLATE MATERIAL SHALL BE PERFORMED

TO DETERMINE BASE METAL THICKNESS.

THICKNESS LESS THAN NOTED BELOW SHALL BE REINFORCED WITH

REINFORCING PLATE OR DEPOSITION OF FILLER METAL AS SHOWN

IN DETAILS ON S-3.

DETERMINATION OF SECTION LOSS SHALL BE MADE BY THE

PROJECT SPECIAL INSPECTOR OR API 653 INPSECTOR.

NOTES: (#)

1. IN AREAS OF STEEL SECTION LOSS EXCEEDING 10% OF THE ORIGINAL MATERIAL THICKNESS, GRIND AREA SMOOTH AND REPLACE WITH WELD METAL TO RESTORE

MATERIAL BACK TO INITIAL THICKNESS. SECTION LOSS FOR AREAS EXCEEDING 4in2 SHALL RECEIVE LAP WELDED PATCH PLATE PER DETAIL ABOVE.

2. ALL WELD INTERSECTIONS SHALL BE AT APPROXIMATELY 90°.

3. PRIOR TO WELDING NEW VERTICAL JOINTS, CUT EXISTING HORIZONTAL WELD FOR A MINIMUM OF 12in. BEYOND THE NEW VERTICAL JOINTS. WELD THE HORIZONTAL JOINT

LAST.

4. PRIOR TO WELDING NEW VERTICAL JOINTS, CUT EXISTING SHELL-TO-BOTTOM PLATE WELDS BEYOND THE NEW VERTICAL JOINTS. THE CUT SHALL EXTEND PAST OR STOP

SHORT OF EXISTING BOTTOM PLATE WELDS BY AT LEAST 3in. OR 5t. WELD THE SHELL-TO-BOTTOM WELD LAST.

5. t = SHELL WALL THICKNESS

6. REPAIR PLATE THICKNESS SHALL MATCH EXISTING SHELL THICKNESS.

2. MINIMUM DISTANCE BETWEEN TWO WELDED ON PATCH PLATES IN THE CRITICAL ZONE SHALL BE ONE HALF OF THE LESSER OF L1 OR L2.

3. THE MAXIMUM DIMENSIONS ALONG THE SHELL FOR WELDED-ON PATCH PLATE IN THE CRITICAL ZONE IS 24-INCHES.

4. WHEN THE EDGE OF A WELDED-ON PATCH PLATE IS APPROXIMATELY PARALLEL TO A BOTTOM SEAM, THE EDGE SHALL BE HELD AT LEAST 2 INCHES

FROM WELD SEAM.

5. PATCHES OVER THREE-PLATE LAPS SHALL EXTEND 12 INCHES MINIMUM BEYOND THE THREE-PLATE LAP.

6. THESE RULES APPLY TO BUTT WELDED BOTTOMS.

7. TANK BOTTOM REPAIR SHALL FOLLOW API 653 SECTION 9.11.1.1 AND 9.11.1.2.

8. CRACKS, GOUGES, TEARS, AND CORRODED AREAS OUTSIDE THE CRITICAL ZONE MAY BE REPAIRED BY DEPOSITION OF WELD METAL. THE REPAIRED

AREA SHALL BE TESTED USING MAGNETIC PARTICLE METHOD OR LIQUID PENETRANT METHOD OR OTHER APPROVED TESTING METHOD.

9. NOTIFY EOR FOR REPAIRS REQUIRED IN THE CRITICAL ZONE.
