Abstract

This paper presents the results of the Davit-Launched Lifeboat Project (DLLBP). The project was initiated by the Norwegian Oil Industry Association (OLF) in December 2009, and was executed as a joint effort between OLF and the Norwegian Shipowners' Association (NSA). The project is a continuation of NSA LAP (Life-saving Appliances Project) and lessons learned in OLF Free Fall Lifeboat Project. The project was organised in six Work Packages (WPs) and was completed in June 2011. The studies in the project covered the following phases during lifeboat evacuation; (1) lifeboat lowering, (2) water entry, (3) release of wire falls and (4) sail-away. Findings and recommendations related to each of the four phases are presented in this paper. The members of the Norwegian Lifeboat Network, consisting of representatives from authorities, unions, suppliers, OLF and NSA, were informed during the course of the project.
