Dear All,
I understand that only waves cause dynamic effect on offshore jackets and current does not contribute in the dynamic behaviour.
I have the following questions regarding to computation of DAF:
1. Is it correct to compute the base shear using ONLY Wave (instead of using Wave + Current)?
2. Will Wave-Current interaction have any impact on the Base shear (static & dynamic) computation?
Is it correct to apply the computed DAF to ONLY Wave component (instead of Wave + Current) during In-service analysis?
Thanks and Regards,

current wil impact velocity of water particle to some extend, and this impact will change wave force on structure. if you want to consider it comprehensively, i think, you should include current effect.
