Catastrophic failure of a polypropylene Tank Part II: comparison of the DVS 2205 code of practice and the design of the Failed Tank
Failure Analysis Case Studies II, 2001Co-Authors: G.w. Weidmann, Peter Rhys LewisAbstract:The design of a Failed, large (20 m3) polypropylene storage Tank is compared with the recommendations of the German Code of Practice, DVS 2205, to which it allegedly conformed. It is shown that the Tank was seriously under-designed, and that the situation was exacerbated by the introduction of residual tensile stresses in its walls during its manufacture. © 1999 Elsevier Science Ltd.

Investigation of method for preventing oil spilled on the ground surface to migrate downwards and contaminate groundwater : Theoretical modeling, experimental study and practical technique
2012Co-Authors: Shahrestanakizadeh MehrasAbstract:The project aims at investigating how effectively the groundwater can be isolated from diesel oil that has leaked from a Failed Tank by covering the ground surface in a few hundred square meters large area confined by soil dikes. The scenario to be considered is a sudden outflow of oil over the ground followed by removal of the oil after a period of time taken here to be 2 weeks. The depth of the oil fill in this period is assumed to be 0.5 m, which will cause oil to penetrate and migrate into the membrane built on the ground surface. The problem to be solved is to predict to what depth the membrane will be contaminated by oil, i.e. how much of it that has to be removed and replaced after the two weeks. The ground surface is assumed to be perfectly horizontal. The project comprised oedometer testing of the artificially prepared membrane clay, which contains a small amount (11 % by weight) and which is a candidate material for isolation of the ground from oil that can leak out from failing Tanks or valves. The oedometer tests were made for determining the (fluid) conductivity and swelling pressure of the membrane material for water and for diesel oil and they were complemented by column tests for simulating of the function when oil is let into air-dry membrane material, and into water saturated material, respectively. The aim was to find out if and how oil molecules move in the membrane.Validerat; 20120918 (anonymous

PROTOCOL FOR ASSESSING THE EXTENT OF CRUDE OIL SPILLED IN A RESIDENTIAL AREA FOLLOWING HURRICANE KATRINA, ST. BERNARD PARISH, LOUISIANA
International Oil Spill Conference Proceedings, 2008Co-Authors: Scott A. Stout, Glenn C. MillnerAbstract:ABSTRACT Floodwater associated with the Hurricane Katrina'S storm surge (August 29, 2005) displaced and damaged a 250,000 barrel above ground storage Tank at Murphy Oil Corporation'S Meraux Refinery in Chalmette, Louisiana. Crude oil was released and was dispersed into the nearby and evacuated residential and commercial area by the retreating floodwaters. The assessment, which began September 18, involved biased sampling and “chemical fingerprinting” of interior and exterior wipe samples (from the visually-evident “bathtub rings” on structures) and interior and exterior sediments from over 6000 homes, businesses, churches, and schools. Crude oil from the Failed Tank was thoroughly characterized using chemical fingerprinting. Over 14,000 Tier 1 (GC/FID) chromatographic (EPA Method 8015B) analyses were conducted as a means of mapping the overall lateral extent, concentration, and continuity of the crude oil impact. These Tier 1 GC/FID analyses revealed the extent of crude oil contamination in the area, as w...
