Experimental and numerical investigations on the collision between offshore wind turbine support structures and service vessels

On the resistance of steel ring-stiffened cylinders subjected to low-velocity mass impact

“…7. This testing frame was successfully used earlier in the impact tests for unstiffened tubular structures [11], beam structures [31] and small-scale tanker double-hull structures [20].…”

Simplified analytical methods for the crashworthiness and the seismic design of lock gates

“…In the literature, most of the available test results have been realized for the shipbuilding, in order to check the safety of vessel regarding oil spills. Amongst others, experiments were conducted by Akita et al [3], Amdahl [8], Cho et al [31], Pedersen et al [130] or Qvist et al [131] . In an illustrative purpose, Figure 2.1 shows the deformation of a tanker double side collided by a rigid ball simulating a striking bow.…”

Ultimate strength of locally damaged steel stiffened cylinders under axial compression

“…In the light of the advancements in the ultimate limit state assessment of steel-plated structures [13], a better understanding of the collapse characteristics of damaged stiffened cylindrical shells predominantly subjected to axial compression is necessary. For the case of tubular members, which have a cylinder radiusover-shell thickness ratio of (R/t) in the range of 20 to 80 [14], the residual strength in damaged condition under various loading conditions has been investigated in a wide range of studies [15][16][17][18][19][20][21][22][23]. According to the statistics [12], a higher collision risk exists for floating platforms than for fixed platforms with mostly tubular members.…”
