ENSURING RELIABILITY OF SHIP HULL STRUCTURES

Although the theoretical and experimental resources available to the ship designer today are much greater than six or even ten years ago, the problems he faces are wider and more complex. The reasons for this include the emergence of new types, the use of new materials in a greater variety of scantlings, new fabrication methods relying on techniques of quality assurance, the growth in size of ships posing problems of structural rigidity (e.g. present-day large tankers are relatively less rigid than ships built in the thirties or forties), the need for inclusion of dynamic loading in design, the increase in ship speeds with problems of vibration and local strength, the increased importance of economic considerations, the need to protect the environment, etc. These factors have led to a new approach to structural design, based on the concept of reliability, which differs from the thinking of the recent past as exemplified by the "classical" theory of structures. Tackling the problems of structural design, including reliability, rests on the basic understanding of the various interacting factors in a way which permits the formulation of mathematical models amenable to numerical methods of solution, and much progress in this mathematical modelling has been achieved in recent years. The Author presents a brief review of the basic ideas which enter into the concept of structural reliability of hull structures. Order from: BSRA as No. 48,985.
