Abstract [en]

High speed vessels are constructed according to the high speed craft codes. These codes enable very light ship structures, which are necessary for effective operation of fast vessels without taking ice loads into account. In the given case a conventional aluminium structure of a high speed ferry designed according to the DNV-GL HSLC code for an operation in Stockholm is investigated. For the determination of the consequences of an impact between a high speed craft and a single ice floe an analytical impact model and a series of drop tests with conical ice specimens against full-scale aluminium panels of the given vessel are presented. Plastic deformations are only observed at the stiffeners and the outer shell. The structural integrity is still given after the tests. The influence of the structural stiffness as well as the limited change in the maximum force at different energy levels during the impact is discussed.
