General

In many contemporary passenger ship designs, the superstructure extends over most of the ship length and the internal structure comprises of a large number of decks connected together with pillars and longitudinal and transverse bulkheads. The structure, in general, has many discontinuities such as knuckle points, recesses, non-continuous bulkheads and decks and geometric irregularities such as openings in decks and bulkheads, as well as many side shell doors and windows. To evaluate the global stiffness of the structure, establish the load path and assess the global and local strength of the design, the use of direct analysis methods is deemed necessary.

Strength analysis carried out in accordance with the procedure outlined in this class guideline will normally be accepted as basis for class approval.

It is recommended that the designer provides the intended analysis procedure for review at an early stage of the design process.

Where in the text it is referred to the rules, the references refer to the latest edition of DNV GL rules for classification of ships.
