LLOYD'S REGISTER'S RULES FOR SHIPS STRUCTURES--A COMBINATION OF THEORY AND EXPERIENCE

The overwhelming majority of the world's seagoing merchant ships are classed with one of the major international classification societies, and the class surveyor is a familiar figure to almost all ships' officers. Of the major classification societies, Lloyd's Register, founded in 1760, is the oldest and largest. Its ship classification service is first described as to its definition, notations, objectives, and implementation. The focus then shifts to Lloyd's Rules for ship structures, Rules whose prime objective is to define a standard of strength that allows ships to fulfill their commercial requirements with what is recognized by a consensus of informed opinion as a proper level of safety. The discussion covers the scope of the Rules, the philosophy underlying them, and their historical development; the procedure for revising rules; the way in which the Rules provide for longitudinal strength, arguably the most important aspect of ship structural strength; the Rules' formulas for local scantlings; and the recognition, in the Rules, of the concept of "equivalence" as a needed way of allowing designers the freedom to innovate.
