Abstract

This paper outlines new scenarios relating to heel and trim to consider for inclusion into an updates "Guidelines for Advanced Analysis for New and Existing Passenger Ships", currently MSC.1/Circ.1238 [1]. It describes the research undertaken as part of the EU FP7 SAFEGUARD project to develop an appropriate set of scenarios and to investigate the impact of the heel scenario on the evacuation of the ship. A wide range of data sources, including statutory regulations, casualty data, damage stability calculations and results of relevant model testing, were utilised to identify appropriates scenarios. The impact of these scenarios was also considered: the primary influence was found to be changes to the travel speeds of the persons due to the conditions experienced. Data from full scale trials in this field was utilised to create speed variation tables which were incorporated into advanced evacuation tools. The identified scenarios were tested using geometries from a cruise ship and a ro-pax ferry and the results of these tests are discussed. Finally, recommendations on implementing these additional scenarios into the regulations are presented
