Directional sea response of a mini-TLP Conference Paper

abstract

• A modified version of an unmanned mini-TLP designed for installation at a deepwater site off the coast of Africa was investigated. Directional seas were not part of the design sea conditions specified for that site in the original design, but were added for this research study. The uni-directional sea conditions originally specified were characterized by a relatively low significant wave height with a long peak period. In this research study more severe seas were introduced, requiring a corresponding increase in deck elevation. The seas the directional seas were described utilizing a single peaked JONSWAP wave spectrum model combined with a Cosine-power spreading function. A comparison of the response of the mini-TLP to unidirectional and directional random seas is presented. Some standard statistical characterizations of the excitation and the response behavior are complemented by three-dimensional and contour interpretations. Further, response of the mini-TLP to head and quartering directional wave con ditions is presented and discussed.
