New Technical Reports Now Available From Ship Structure Committee
The Ship Structure Committee has recently published three new technical reports which are available free of charge. SSC-297, "Evaluation of Liquid Dynamic Loads in Slack LNG Cargo Tanks," presents a review of worldwide scale model sloshing data and reduces the data to a common format for the purpose of design load coefficients. Additional scale model laboratory experiments have been conducted to supplement the available model sloshing data.
SSC-298, " I n v e s t i g a t i o n of Steels for Improved Weldability in Ship Construction—Phase 1," is the initial effort of an ongoing project to minimize heat-affected zone and weld-metal property degradation for high desposition rate welding. Two production steels and 20 laboratory heats of steels of various chemical compositions have been recommended for further examination.
SSC-299, "Ultimate Strength of a Ship's Hull Girder in Plastic and Buckling Modes," analyzes limiting conditions beyond which a ship's hull girder will fail to perform its function. Vertical and lateral bending moments and torsional moments are used to develop a procedure for estimating the ultimate capacity of the hull.
