Damage Assessment After Accidental Events : Report of Committee V.1

• This paper contains the report of the Committee, which is a new one that was created todeal with the methods to assess damage and residual strength after accidental events.The name of the committee, being a short one may give a wrong impression about itsscope as it mentions damage assessment while the mandate refers that there should beconcern for the extent of damage and local and global residual strength of shipstructures, after accidental events. Therefore the contents of the report deal also withmethods to determine local and global residual strength, including the specification ofthe appropriate loads.It starts by providing a description of the type of damages that can be found in thevarious accidental events. Representative scenarios are described and the typicaldamages that results from the specific accidents are indicated. Next section describeshow in real situations the damaged state is perceived. Thus, inspection methods aredescribed as well as the available approaches to derive information about the status ofthe structure from indirect measurements.Loads on the structure are treated afterwards, including the loads that are generatedduring the accidental situation itself and also after the accident when the ship is indamaged state, often listed and with non symmetric sections. The loads are used todetermine ship strength using the assessment methods described in section 5, whichdeals with various types of components.If the ship is considered not having enough strength for temporary voyage to repairyard local repairs are necessary. Otherwise she will travel to a repair shipyard and berepaired there. The various types of problems raised in repair are dealt with in thefollowing section.Finally last section deals with salvage and recovery strategies which are necessary inthe cases of very large damage in ships.
