The Ship Structure Committee, an Interagency Advisory Committee dedicated to improving the structure of ships, has recently published three new technical reports that 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, "Investigation 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 deposition 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.
