摘要

In February 2011 during a routine trial, a 6.5m ship’s Fast Rescue Boat parted from its davit wire and fell 29 metres,rncausing a fatality. Following the accident, the Marine Accident Investigation Branch found that the vessel wasrnsignificantly heavier than originally designed. This paper describes the subsequent investigation into the causes andrneffects of the identified weight growth. The full destructive testing of a representative Fast Rescue Boat and the criticalrnassessment of its structure is detailed. Practical SOLAS-based trials are also described whereby the effects of weightrnincrease on the safe functionality of the boat are assessed. These trials have determined that the use of in-built buoyancyrnfoam, in association with the wider design approaches to such craft, can lead to the possibility of water retention. Thernassociated weight growth can lead to the significant erosion of lifting safety factors and can have catastrophicrnconsequences if not managed correctly. The use of buoyancy foam is common place across the industry; however it isrnproposed that the associated concerns through life may not be obvious to key stakeholders. Despite the apparentrntechnical simplicity of such craft, risks to the safety of the crew and the reputation of the vessel operator are significant.rnThis paper highlights some of the critical issues for buyers, designers, owners, operators and maintainers of RescuernBoats, Fast Rescue Boats and Lifeboats.
