Structural Analysis of Composite Search and Rescue Vessels under the New BS EN ISO 12215-5

Abstract

Amongst the new implementations to the forthcoming BS EN ISO 12215-5 features a workboat annex, namely Annex J. This will allow vessels in professional use, such as search and rescue crafts, to be designed under the updated regulation. Moreover, to account for the increasing design and operating speeds since the previous BS EN ISO 12215-5 published in 2008, the scope has been extended beyond 50 knots, while also accounting for higher accelerations. The technical background and practical applications of the new regulation for composite vessels will be presented, highlighting the increased factors of safety adopted to ensure reliability and account for the operating profile of the vessels.
