Abstract
Oil exploration in water deeper than 1000 feet has
motivated the development of drilling platforms with
dynamic responses superior to those of the conventional
jacket structures. One of the most promising of these
is the tension leg platform (TLP) , a semi-submersible
platform held in place by tension members connected to
the ocean bottom.
This thesis evaluates the wave force transfer function
for the TLP in heave, pitch, and roll motions. This is
accomplished by assuming the transfer function for a
single leg and then extending that result to include the
effect of phase differences between forces on multiple
legs, including the effect of wave spreading.
