Fractal column offset tension leg platform (COTLP)

A Fractal Column Offset Tension Leg Platform (COTLP) consists of a semi-submersible hull type, tension moored to the seabed. The Fractal COTLP advances the state of technology by utilizing fractal arrangements of repeated, similar structural units, consisting of continuous pontoons and intermittent columns, to provide better construction, operation, stability, payload and service life advantages over existing Tension Leg Platform (TLP) types. Varying, fractal-like geometric arrangements also provide for sizing and configuration advantages and the capability to work in greater water depths than existing TLP technology. Furthermore, fractal arrangements and inter-column spacing can also be optimized to minimize platform hydrodynamic response to waves, thereby reducing mooring and hydrodynamic loads and consequently achieving an optimal and safer platform structure with a longer fatigue life.
