Ship Structure Committee Releases New Reports On Design And Safety Topics

The Ship Structure Committee, an Interagency Advisory Committee dedicated to the improvement of marine structures, has recently published some new technical reports of interest to those concerned with the design and safety of ships and offshore structures. Among the new reports are the following: SSC-317—"Determination of Strain Rates in Ship Hull Structures: A Feasibility Study" This report presents a survey of existing data on shipboard stress/ strain rates. The data bases are evaluated and strain rates from existing ship data are developed.

SSC-321—"Survey of Experience Using Reinforced Concrete in Floating Marine Structures" This report reviews applications of marine concrete structures, research into concrete structures, and inspection and repair of these struc- tures, and presents an extended bibliography on the subject. SSC-323—" U p d a t i n g Fillet Weld Strength Parameters for Commercial Shipbuilding" This report presents a possible alternative method of assessing fillet weld requirements to the ABS weld tables.

SSC-326—"Long-Term Corrosion Fatigue of Welded Marine Steels" This report represents a first look at corrosion fatigue by the Ship Structure Committee. It assesses those future directions that would be most fruitful for further study, approaching fatigue from both the deterministic and the probabilistic viewpoints.

SSC-327—" I n v e s t i g a t i o n of Steels for Improved Weldability in Ship Construction" This report is direct toward determining the weld procedure and metallurgical control necessary to develop adequate toughness in the weldment, using high-deposition rate weld procedures. This report is the third and final phase of the welding effort, and follows SSC-298 and SSC-305.

For copies of the reports or further information, contact Lt. Cdr. Thomas H. Gilmour, Secretary, Ship Structure Committee, U.S. Coast Guard (G-MTH-5), 2100 Second Street S.W., Washington, D.C. 20593.
