  • Tension leg platform anchoring method and apparatus
    Patent number: 4620820
    Abstract: A method and apparatus is presented for anchoring a tension leg platform to the ocean floor using an anchor having an upper and lower assembly. The anchor's upper assembly is operatively connected to the lower ends of the tethers forming the tension legs of the tension leg platform, and acts to space and align each tether in a vertical manner when the anchor's upper assembly is connected to the anchor's lower assembly, which has previously been secured to the ocean floor by anchor piles.

  • Curved conductor well template
    Patent number: 4591295
    Abstract: An anchored submerged marine structure commonly referred to as a well template is located at the bottom of a body of water and used in the directional drilling of underwater wells. The well template carries curved well conductors, each conductor capable of deviating well drilling equipment passed through the conductor so that each well may reach reservoirs located a further distance away from the template. The template's upper surface is formed to aid in the installation of the well conductor through the template.

  • Pitch period reduction apparatus for tension leg platforms
    Patent number: 4585373
    Abstract: A tension leg platform is provided with exterior buoyant columns located outside the normal tension leg platform structure. The exterior columns decrease the pitch period of the tension leg platform away from the point of concentration of the largest wave spectrum energy encountered at a particular marine location. Modification of the pitch period of the tension leg platform in this manner reduces the cyclic fatigue stresses in the tension legs of the platform, and thereby increases the useful life of the platform structure.
