Second generation of intact ship stability criteria according to IMO

The article presents conclusions from the work of the SLF Sub-Committee on the development of second-generation stability criteria. The currently used approach to ensuring ship stability safety is presented along with a critical assessment. Actions taken by the IMO to improve the intact stability safety of ships are described. The concept of vulnerability criteria, on which the second-generation criteria are being developed, is also presented.In ancient times, sea voyages were burdened with a high risk of loss of life and property, as well as environmental pollution. At that time, the enormous risk associated with sea travel on board a ship was widely known and accepted, while knowledge of how to build safe ships was based solely on experience gained through trial and error. The errors were, of course, maritime disasters. Conclusions drawn from accidents allowed for the creation of an outline of recommendations regarding the proper proportions and dimensions of the ship’s hull and its construction, which were intended to ensure stability and good seakeeping properties. These recommendations were passed down from generation to generation among shipbuilders and were closely guarded.
In today’s world, the significant risk accompanying sea voyages can no longer be accepted. Therefore, all possible actions are being taken to reduce it. (…)
