Rules For Floating Dry Dock Construction Published By ABS A new Rule book, "Rules for Building and Classing Steel Float- ing Dry Docks," has been pub- lished by the American Bureau of Shipping (ABS). The Rules apply to floating dry docks over 61 meters (200 feet) in length, but can be applied, subject to special considerations, to smaller structures. The 56-page volume is the 24th set of standards to be issued by the international ship classifica- tion society. It consists of sec- tions giving requirements for hull construction, machinery, testing, and surveys after construction. The Rules also discuss the towing of dry docks in other than shel- tered waters. The new Rules were developed by ABS with the assistance of an industry Panel on Floating Dry Docks. This eight-member advi- sory panel, formed by ABS in October 1973, consists of dry dock designers, operators, and builders. ABS has been publishing stand- ards for vessel design and con- struction since 1870, when it is- sued "Rules for the Construction and Classification of Wooden Ves- sels." The Steel Rules were first published in 1890, and are up- dated and published annually. The new Dry Dock Rules are available from the Book Order Section of ABS, 45 Broad Street, New York, N.Y. 10004. The price is $5, or equivalent currency, plus local tax where applicable.
