Exploring the Design Envelope for Enhanced Design & Operation of Search & Rescue Craft
17th April, 2018, RINA HQ, London
Afternoon workshop (13:00 – 17:00pm) reporting on the results of research collaboration between the RNLI, Newcastle University and Lloyd’s Register
The design and development of a new lifeboat class is a long and intense process, which involves model testing, sea trials and periods of evaluation before the new lifeboat enters service. Due to a number of reasons, including considerations of the service life of a lifeboat, the need to respond to changing patterns of casualties and the possibility to embed new materials and technologies that become available, lifeboat classes are only replaced after extended years of service. This period of time has typically been 25 years for the lifeboats designed and employed by the Royal National Lifeboat Institution (RNLI) with a view now to extend the life of the Severn Class to 50 years.
Traditionally the crew endurance has been one of the limitations to speed when operating in waves. New technologies to increase the ride quality are available, which also provide the potential to operate closer to the structural limit of the vessel. Furthermore, with improved seat protection, the perception of the coxswain in charge of the lifeboat could limit their ability to appreciate the slamming loads being sustained by the structure. An enhanced insight into the structural response to the wave loads sustained and of the crew endurance is required to prevent operation close or even beyond the structural limit and therefore the occurrence of structural failures.
The RNLI has been working with Newcastle University and Lloyd’s Register to develop a series of methodologies and tools for the design, maintenance, training and operation of high-speed search and rescue craft. The project has involved model and full scale testing, numerical simulations and interaction with RNLI user groups. This dissemination event is to share the main findings from the project to date and to trigger discussion about best practice now and in the future development of high-speed rescue craft.

SURV 9 - Surveillance, Search and Rescue Craft Conference on 18 April 2018, London, UK
The Royal Institution of Naval Architects (RINA) will continue its successful SURV series of International Conferences now in its ninth edition. The conference will provide a forum for discussion of both military and civilian vessels. We hope to include papers across the full range of vessels, equipment and methods, used by pilot craft, coastguards, and police as well as search and rescue organisations. Topics will include analysis of new designs, applications, and operations of these vessels, as well as review existing vessels and their use across all marine environments.
