Chapter 1, Section 3Common Structural Rules for Bulk Carriers2. Definition of functional requirements2.1 General2.1.1The functional requirements relevant to the ship structure are indicated in [2.2] to [2.6].2.2 Structural strength2.2.1Ships are to be designed to withstand, in the intact condition, the environmental conditions during the design life,for the appropriate loading conditions. Structural strength is to be determined against buckling and yielding.Ultimate strength calculations have to include ultimate hull girder capacity and ultimate strength of plates andstiffeners.2.2.2Ships are to be designed to have sufficient reserve strength to withstand the wave and internal loads in damagedconditions that are reasonably foreseeable, e.g. collision, grounding or flooding scenarios. Residual strengthcalculations are to take into account the ultimate reserve capacity of the hull girder, considering permanentdeformation and post-buckling behaviour.2.2.3Ships are to be assessed according to the expected design fatigue life for representative structural details.2.3 Coating2.3.1Coating, where required, is to be selected as a function of the declared use of the ship spaces, e.g. holds, tanks,cofferdams, etc., materials and application of other corrosion prevention systems, e.g. cathodic protection orother alternative means. The protective coating systems, applied and maintained in accordance withmanufacturer’s specifications concerning steel preparation, coating selection, application and maintenance, are tocomply with the SOLAS requirements, the flag administration requirements and the Owner specifications.2.4 Corrosion addition2.4.1The corrosion addition to be added to the net scantling required by structural strength calculations is to beadequate for the operating life. The corrosion addition is to be assigned in accordance with the use and exposureof internal and external structure to corrosive agents, such as water, cargo or corrosive atmosphere, in addition tothe corrosion prevention systems, e.g. coating, cathodic protection or by alternative means.Page 12 July 2008
