General The design and construction of the hull@ superstructure and deckhouses of container carriers are to be based on the applicable requirements of the ABS Rules and Guides. As a supplement to the ABS Rules and Guides@ these Guidance Notes provide detailed procedures for whipping assessment for container carriers. The procedure is easy to use and can be utilized to make quick estimates of the whipping effect on hull girder bending moment and on fatigue load. It could be utilized during the conceptual design phase and to perform a sensitivity study of its variation with main dimensions and operational profiles. The technical background is based on the direct analysis of slamming load and structure dynamic response. The procedure has been calibrated using a number of existing designs.
