WATER IMPACT LOADS AND DYNAMIC RESPONSE OF HORIZONTAL CIRCULAR CYLINDERS IN OFFSHORE STRUCTURES

The first part of the paper studies the loads on a rigid horizontal circular cylinder that is forced with constant velocity through the water surface. It is found that the slamming force coefficient is equal to 3,1 (numerical estimates), while experiments give an average value of 5,3. The second part of the paper studies the dynamic response of flexible horizontal circular cylinders that are forced through the water surface. Scaling of model test results give significant stresses for horizontal trusses of north sea structures.
