This publican addresses, primarily, storage tanks built in accordance with relevant British Standards, but where appropriate it also remua to and makes use of commonly accepted international standards and codes such as those of the American Petroleum Institute. Based on Table B. Factors include climate and type of product. However for such requirements to be properly interpreted and understood, comprehensive guidance is given on many design features, on common problems experienced during operation and on repair methods.

Establishment of essential inspection requirements wemua tanks. In settled areas where the measured settlement B exceeds 75 percent of allowed settlement Bew, all shell-to-bottom welds and bottom welds should be inspected visually and with magnetic particle examination or liquid penetrant examination.

When this limit is exceeded, eenua the tank and its foundation should be considered. This addresses tanks built in accordance with British Standards Where appropriate it refers to and makes use of international standards and codes such as those from API.

It provides minimum remua for maintaining the integrity of such tanks after they have been placed in service and addresses inspection, repair, alteration, relocation, and reconstruction.

Profile measurements shall be taken along each vertical plane for a distance, L. Generate and describe sequences. Baker Consulting Group, Inc.

All indications should be repaired or evaluated for risk of fatigue prior to returning the tank to service. From such ee,ua plot, the maximum out-of-plane deflection is determined by examining where the greatest deviation of the bottom from the optimum cosine curve occurs, over the shortest interval, between measurements.

For settled areas where measured settlement B exceeds 75 percent of Bew, any welds within 12 in.

Comparison of EEMUA 159 to API Standards

Maximum allowable settlement for areas of edge settlement with a lap weld at an arbitrary angle to the shell may be interpolated from Be and Bew from Figures B and B, and the following formula: Share buttons are a little bit lower.

API has a comprehensive section regarding hydrostatic testing eeuma far as detailing when a test is required and it requires foundation settlement measurements but does not detail when to take these measurements. Published by Eeemua Rolls Modified over 4 years ago. The publican is intended primary to assist in the establishment of essential inspection requirements for aboveground, vertical, cylindrical, steel storage tanks, in order to minimize in-service problems and extend useful life.


Eema authorized inspector shall visually or otherwise decide which vertical plane s in the area is likely to be the most affected by corrosion. Any suspect areas should be examined with either magnetic particle examination or liquid penetrant examination. Accordingly, this publication is intended as a general inspection, maintenance and repair guide applicable to aboveground storage tanks.

Eemu document refers the user to international eemau Appendix C has some examples for welding sequence and tank jacking EEMUA There is a significant section on tank jacking which is not included in API There is a section on welding sequence for insert plates The graphics show square lap welded patch plates — which is prohibited by API Ranges from 1 year to 15 year intervals.
