Hawaii's Floating City Development Program: Theoretical Investigations And Optimization Of The Platform's Seakeeping Characteristics

This report of Hawaii's Floating City preliminary engineering work presents the methods and findings of the initial theoretical investigations of the floating platform's seakeeping characteristics. It also provides recommendations for design refinements that v ill minimize platform motions and acceleration forces in the seaways expected to prevail at the proposed installation site. Since single column heave response is of high importance, this facet is explored in detail first. Then equations of motion in six degrees of freedom are developed for a 3-column single module of the ten-module core-ring of the city and finally for the 30-column core-ring in its entirety. These equations have been expressed in FORTRAN IV and mathematical simulations for various configurations in regular and irregular seas run on an IBM 360/65 computer. Grant no. 2-35243
