FINAL PHASE 09 REPORT ON TANKS, FITTINGS, AND ATTACHMENTS IN THE MECHANICAL ENVIRONMENT OF ACCIDENTS
Phase 09 of the RPI-AAR Tank Car Safety Research and Test Project concerns the behavior of tank car tanks and their appurtenances in the mechanical environment of railroad accidents. Thus, the items treated under this Phase 09 are: Tank shell - the portion of the tank between the heads, Tank fittings - the appurtenances attached to the tank shell and heads which are associated with openings through the vessel wall, and tank attachments - appurtenances attached to the tank shell and heads which are not associated with openings through the vessel wall. As an underlying principle, in the cost/benefit analyses under this study, the benefit values of design improvements, such as protective devices or "shields," are developed from accident data only from cases involving lading loss, the total dollar losses being the value of the lost lading plus that of subsequent losses caused by the lading loss. The cost of mechanical damage itself to shells or appurtenances is not considered reducible by a design change, it being assumed that the cost of repairing the "shield" is the same as that of repairing the unshielded item. Following the statement of the objective, the report comprises four main sections: (1) review of typical current tank car shell and appurtenance designs, (2) review and analysis of accident data, (3) discussion and conclusions, and (4) recommendations.
