The course will give a brief overview of Ultimate load design principles and plastic capacity of sections  Capacity estimate of tubular joints under axial, flexural and torsional buckling will be discussed. Fundamentals of impact analysis and its application to collision problems on marine structures will be also highlighted. A brief section on fluid-structure interaction highlighting flow induced vibration will be presented. Introductory topics on reliability of marine structures including FOSM and AFSOM methods will be also discussed. Concepts of fatigue analysis and design of marine structures will be presented. The focus is on detailed explanation of topics through numerical examples.
