The designs of a large aluminum bulk carrier and an equivalent steel ship are presented and compared. The aluminum ships structure weighs 43 per cent less than the steel ship, and its hull is about 50 per cent more flexible. Cargo deadweight is increased 7-1/2 per cent. Cost studies indicate that for the same return on investment the
ABS RULES FOR STEEL VESSELS UNDER 90 METERS (295 USCG Marine Safety Manual, the ABS Steel Vessel Rules, the ABS Steel Vessels Under 90 Meters Rule, and this Supplement. A vessel enrolled in the Alternate Compliance Program must satisfy all the requirements contained in the applicable sections of the International Conventions, ABS Rules and the U.S. Supplement, prior to the issuance of the COI.
ABS Common Strength Shipbuilding Steel Grade Overview. The common strength shipbuilding structure steel is divided into four grades A, B, C, and D. The yield strength of these four grades of steel (not less than 235N/mm^2) and the tensile strength (400~520N/mm^2) are the same. , but the impact energy at different temperatures is different;

SHIP STRUCTURE COMMITTEE 2012The USCG requested the Ship Structure Committee (SSC) to conduct a study to review industry experience of fractures and fracture repairs, and to develop a comprehensive and usable steel hull fracture repair guide that would eventually assist in the revision of NVIC 7 ABS RULES FOR STEEL VESSELS FOR VESSELS ON ABS Rules for Steel Vessels for Vessels on International Voyages." This Supplement identifies those USCG requirements which are in addition to the ABS Rules and the International Conventions. This publication is intended to be used in lieu of 46 CFR Subchapters "D" and "I" for plan review and inspections delegated to ABS by the USCG.
