Abstract
Analytical procedures are presented for analysis of the external dynamics of ship collisions against bottom supported flexible as well as rigid offshore structures such as wind turbine structures, quays and bridge piers. Based on the principles of conservation of momentum and energy algebraic expressions are derived for the maximum values of collision forces and energy released for local crushing. The expressions are derived for arbitrary impact locations and they are well suited for application in risk analysis procedures. Numerical results show that for piled towers the structural flexibility plays an important role for reduction of the structural damage. For gravity based foundations it is shown that provided some limited foundation displacements can be allowed then the requirements to the shear sliding force capacity can be reduced significantly. © 2013 Taylor & Francis Group.
