✦ Synopsis

North Sea collision accident records covering a period often years indicate that the risk of collisions involving jack-ups is not dissimilar to that for semisubmersibles or fixed jacket structures. However. jack-ups are much more flexible than jackets and have a much lower degree of redundancy. Their response to collisions and their ability to absorb impact energy is, therefore, expected to be considerably different in comparison to jackets. This paper examines available data and information regarding the capability ofjack-ups to withstand collision impacts and investigates the level of local damage that can potentially be caused to jack-up legs due to accidental collisions.
