Notes: / The red text indicates the changes made to this agenda item as a result of the Fall 2008 ballot and represents the portions of this item being balloted.
Proposal:
13.1.1 Reconstructed Tanks
13.1.1.1 – Existing paragraph 13.1.1
13.1.1.2 – Existing paragraph 13.1.2
13.1.2 Tanks Without Nameplates
At the owner’s request a nameplate may be attached to a tank meeting the requirements below.
13.1.2.1 If information required to complete the nameplate as required by the as-built standard is available and traceable to the tank, a new Replacement Nameplate, similar to that shown in Figure 10-1 in API 650, may be attached under the direction of the Authorized Inspector. The new nameplate shall contain all of the information required by the as-built standard and be marked ‘Replacement Nameplate’.
13.1.2.2 If information required to complete the nameplate as required by the as-built standard is not available, the suitability for service of the tank shall be evaluated under the rules of API 653, Sections 4 and 5. If the tank is found to be suitable for service, an ‘Assessment Nameplate’ may be attached under the direction of the Authorized Inspector, provided a suitability for service assessment is performed per API 653 Sections 4 and 5, . The new nameplate shall contain the following information:
a. API Standard 653 – ‘Assessment Nameplate’.
b. Owner’s tank number.
c. The company performing person(s) (e.g. storage tank engineer or authorized inspector) responsible for the final acceptance of the assessment.
d. The date the assessment was performed.
e. The date of the edition and the addendum number of API 653 used to perform the assessment.
f. The nominal diameter and nominal height, in meters (ft. and in.).
g. The maximum capacity in m3 (42-gallon barrels).
h. The liquid level in meters (ft. and in.) used to perform the assessment.
i. The specific gravity of the liquid used to perform the assessment.
j. The design metal temperature in oC (oF) used to perform the assessment.
k. The pressure used to perform the assessment.
l. The maximum design temperature in oC (oF) used to perform the assessment.
km. The material specification, if known, for each shell course.
ln. The allowable stress values in MPa (psi) used to perform the assessment.
o. The joint efficiency used to perform the assessment (see 4.3.3. or 4.3.4)
13.1.2.3 The nameplate shall be made of a corrosion resistant metal embossed, engraved, or stamped with letters and numerals not less than 4 mm (5/32”) high. Nameplates shall be attached as specified in API Std. 650. In addition, the nameplate shall be clearly marked as an API 653 ‘ ‘Assessment Nameplate’. Refer to Figure 13-2.

Note: See 13.1.2.2 a. thru o. regarding nameplate information requirements.
Editors Note: Existing Figure 13-2 ‘Certification Forms’ will become new Figure 13-3.
For clarity, existing Figure 13-1 should be re-titled: ‘Reconstruction Nameplate’
