..., this specification does not consider the absorption of the impact energy by seabed and soil covered on the pipelines, resulting in a conservative assessment. Some scholars have explored the response of submarine pipelines to the impact of dropped objects. The interaction between pipe and soil is a complex process...

ABSTRACT In this paper, the results of model tests of impact energy and forces of moor ed ships from 20,000 dwt to 200,000 dwt in regular waves upon piers ace synthetically analyzed. Based on the concept of Wave energy transmi- ssion and the theory of vibration , a semi...
