ALLOWANCE FOR IMPERFECTIONS IN SHIP STRUCTURAL DESIGN

The development of quality standards in shipbuilding is reviewed, and the need for an analytical assessment of standards identified. The use of a probabilistic approach in the form of a reliability analysis is recommended, and a description of a system suitable for this task given. The various levels of complexity which may be involved are described, and the problems of implementation outlined. The method is illustrated by an application of the system developed at Lloyd's Register of Shipping to assess suitable quality standards for initial imperfections in ship plating. To correlate the mathematical simulation of reliability with actual experience, use is made of technical information on structural damages from Lloyd's Register of Shipping Technical Records database.
