See a ship would go having a resonance period high, but it goes up, but here what
happened? It actually resonance is somewhere here, but at the resonance the excitation is
small. So, although it is resonating the motion is smaller than even 1. So, you see, it will
resonate, but because exiting force is small everything is small it resonance, but heave is
very small, this is this is an idea of you know, this is semisubmersible type and this is a
typical ship ok. Now, this is where I will go to enter this regular wave part, but I the
reason this I say that after all irregular regular is integrated connected to we will find out,
we will see that how a vessel behaves in irregular waves is completely decided by how it
behaves in regular waves. Therefore, it is very more important actually to solve this part,
then to solve the irregular wave part.
