New requirements for lifeboat hooks : A study on how MSC.320(89) has influenced safety concerning the handling of lifeboats (English)
Abstract [sv]

Sedan implementeringen av on-load release funktionen på samtliga livbåtskrokar har det skett många olyckor som följd av introduktionen med detta system. Detta problem diskuterades under Internationella Maritima Organisationens Maritime Safety Committee, 89:e sammanträde 2011. Under detta sammanträde utvecklades ändringar och tillägg till koden för International Life-Saving Appliances med syfte att bemöta detta problem. Fokus för denna studien är resolution MSC.320(89) vilket formulerades under det sistnämnda mötet. Resolutionen lade fram nya krav rörande on-load release livbåtskrokar. Syftet med denna studie är att förstå hur MSC.320(89) har påverkat säkerheten vid hantering av livbåtar. Studien har utförts genom en kvalitativ litteraturstudie med komplementerande intervju. Genom att jämföra orsakande faktorer vid livbåtsolyckor med det nya kraven så har man kunnat spekulera fram positiva effekter gällande säkerheten. Implementeringsprocessen består av godkännande för utformning och funktion, rigorösa tester iland, samt granskningskrav för samtliga ombordvarande system. Minskning i antalet rapporter om olyckor vilket sker till följd av on-load release krokar efter implementeringsprocessen av MSC.320(89) tyder på att det sker ett färre antal olyckor relaterade till on-load release system. Denna minskning kan möjligtvis påverkas av implementeringen med fallprevention devices vilket kan ha som effekt att maskera svikt av on-load release system. Det övergripande resultatet från studien tyder på att MSC.320(89) har haft en positiv inverkan vad gäller säkerheten vid hantering av livbåtar.

Abstract [en]

There have occured many accidents as a result of the mandatory implementation of on-load release mechanisms on all lifeboats. In order to combat the problem amendments to the International Convention for the Safety of Life at Sea and the International Life-Saving Appliances Code were put forth during the Maritime Safety Committee, 89th session, 2011. The focus of this study lies on a product of this meeting: resolution MSC.320(89). The resolution presents new requirements for the design and function of on-load release systems. The purpose of this study is to understand how MSC.320(89) has influenced safety concerning the handling of lifeboats. A qualitative literature study with a complementary interview was used to conduct this study. By comparing causal factors of accidents involving on-load release systems with the new requirements stated in MSC.320(89) speculations could be made pertaining to improved safety conditions. The implementation process for the new requirements included a design review and performance test of existing and new on-load release and recovery systems. Moreover all systems onboard merchant vessels were either inspected, modified or replaced in order to be made compliant with the amended Life-Saving Appliance code. A decline in the number of accident reports concerning on-load release systems following implementation was observed during the data collection phase of this study. This decline may imply a reduction in the number of accidents caused by on-load release systems however the use of fall-prevention devices may have stopped failing on-load release systems from ending in catastrophe. The overriding conclusion of this study infers that resolution MSC.320(89) has effected safety concerning the handling of lifeboats in a positive manner.
