31、nd re-commended provisions in part B relating to intact stability, based primarilyon existing IMO instruments. Where recommendations in this Code appearto differ from other IMO Codes, the other Codes should be taken as theprevailing instrument. For the sake of completeness and for the con-venience o

32、f the user, this Code also contains relevant provisions frommandatory IMO instruments.2 The criteria included in the Code are based on the best state-of-the-art concepts, available at the time they were developed, taking into ac-count sound design and engineering principles and experience gained fro

33、moperatingships.Furthermore,designtechnology for modern ships is rapidlyevolving and the Code should not remain static but should be re-evaluatedand revised, as necessary. To this end, the Organization will periodicallyreviewtheCodetakingintoconsideration both experience and furtherdevelopment.3 A n

34、umber of influences such as the dead ship condition, wind onships with large windage area, rolling characteristics, severe seas, etc., weretaken into account based on the state-of-the-art technology and knowledgeat the time of the development of the Code.4 It was recognized that in view of a wide va

35、riety of types, sizes ofships and their operating and environmental conditions, problems of safetyagainst accidents related to stability have generally not yet been solved. Inparticular, the safety of a ship in a seaway involves complex hydrodynamicphenomena which up to now have not been fully inves

36、tigated and under-stood. Motion of ships in a seaway should be treated as a dynamical systemand relationships between ship and environmental conditions such as waveand wind excitations arerecognizedasextremelyimportantelements.Based on hydrodynamic aspects and stability analysis of a ship in a seawa
