Parametric Study of TLPs Subjected to Random Waves

TLP technology preserves many of the operational advantages of a fixed platform while reducing the cost of production in deep water. The amplitudes of motion must be sufficiently small to prevent flexural yielding of the drilling risers which connect the platform to the sea bed template. In this p...
