STRUCTURAL DESIGN REVIEW OF LONG, CYLINDRICAL, LIQUID-FILLED INDEPENDENT CARGO TANK BARGES

This report describes a program of analytical research to determine the availability of reliable methods for the design of long, large diameter, cylindrical tanks and their supports for transportation of liquids and low-pressure liquefied gases in barges for service on rivers or at sea. Loading conditions, existing design/analysis methods, material considerations, and a computer method for predicting stresses are presented. The major conclusion of the work performed is that design procedures for river barge tanks up to 20 feet in diameter are well established and that no failures due to inadequate design practice have been reported since refrigerated tanks went into service ten years ago. The present method for designing river barge tanks is a logical starting point for determining the structural configuration of large tanks for oceanic service, but more detailed analysis of loads and resulting stresses should be performed for this application. Several areas in which theoretical or experimental effort is needed are identified: (1) investigation of tank-saddle-barge interaction, (2) investigation of fatigue criteria for cyclic loading, (3) investigation of buckling criteria, (4) analytical and experimental investigation of slamming, and (5) experimental verification of stresses in a full-scale tank.
