Design & Verification Methodologies
Technical Bulletin 2012
Existing class society procedures are based on the prescriptive approach, which implicitly includes a number of different empirical assumptions and a number of important safety factors. The main objective of the specific design methodology procedures is to rationalize the design verification procedures by reducing various uncertainties. Significant improvements to the direct hydro-structure interaction tools have made possible the application of rational methodology. The rational choice of operational conditions remains the main issue. It appears that the software needs to be adapted to reflect more accurately the global navigation conditions encountered by merchant ships, in order to achieve a more realistic ship operational profile. Work on harmonization of the rule and direct calculation approach is ongoing within BV’s Research Department. This is true both for global structural responses as well as for some local issues such as slamming or sloshing impact. Bureau Veritas is the global leader in this field, and the papers presented in this section reflect the state-of-the art technology which is being used and which is becoming increasingly important.
