Application of Advanced Analysis Methods to the Life Cycle Management of Ship Structures

Abstract

In the process of initiating more efficient maintenance practices for the new Halifax Class frigates, the requirement for an effective means to assess operational structural integrity arose. This paper describes the general plan for a five year development project entitled 'Improved Ship Structural Maintenance Management' - ISSMM, begun in 1996 with the goal of producing a tool which will use modern methods of analysis to efficiently assess the operational capability of the Halifax Class structure in an intact, degraded or damaged condition. The overall philosophy and general approach to the development of sea load models, structural analysis methods for fatigue and strength, damage modelling, the assessment of residual strength and risk of operation, and verification through component testing and sea trials are discussed.
