The study is of an offshore structure consisting of slender columns near the free surface and large buoyancy pontoons near the base that is moored to the sea bottom like a Tension Leg Platform. The effect of the spacing between the columns of the structure on the horizontal component of the total wave force due to an irregular wave has been investigated. Since the columns are slender, diffraction of the incident wave field has been neglected and the wave force has been computed using a method proposed by Borgman for an irregular wave. This research has been done to get an insight into the design of an offshore structure that will experience low horizontal force. The sea state considered is one having a significant wave height of 6m and a mean wave period of 6s since the probability of exceedance of this sea state is low in the west coast of India where the use of this structure is contemplated.
