The section on fire detection, prevention and extinction has been completely rewritten. A major revision of the Rules such as this has involved the co- ordination of an immense amount of effort in technical, editorial and production departments. A steer- ing committee was established in 1974 to study the format of the Rules and to make recommenda- tions for their improvement. It has also met weekly since Jan- uary 1976 to provide direction and monitor progress. Mr. Hildrew said: "We recog- nized the need to present the Rules in a more logical sequence to make them easier for subscrib- ers to use, and while there have been substantial changes to the 1976 Rules (no Rules were issued in 1977—deliberately), the Soci- ety hopes the restructuring of the 1978 Rules will enable the user to more effectively expedite his designs." The Rules are now organized in seven basic parts with 61 in- dividual chapters as follows: PART 1. Classification regula- tions. PART 2. Requirements for ma- terials used for ship and ma- chinery construction, including requirements relating to steel plates, castings, forgings, pipes and tubes and welding consum- ables. PART 3. The basic structural design philosophy of hull con- struction, longitudinal strength, aft-end structures, superstruc- tures, etc. PART 4. Hull construction re- quirements for specific ship types, e.g., tugs, ferries, bulk carriers, oil tankers, and containerships. (Two new class notations have been introduced — "100A1 Bulk Carrier," and 100A1 Container Ship.") PART 5. Main and auxiliary machinery, including shaft vi- bration and alignment and piping systems for oil and chemical tankers. PART 6. Automation and con- trol systems, electrical systems, refrigeration systems, and fire prevention systems. PART 7. Highly specialized ships to which the format of the rest of the Rules cannot easily be applied, e.g., nuclear ships. The complete set of the 1978 Rules will cost $150, which in- cludes the service of providing updated sections for a period of five years. However, "Extracts" from the Rules will continue to be available at prices from $1.75 to $29.75, depending on the size and content of each extract. The price includes an updating service. German, French and Spanish editions of the New Rules will be available early next year.
