Abstract: A well tender system for controlling, separating, storing and offloading well fluids produced from subsea hydrocarbon formations. The system comprises a vertically aligned series of tethered cylindrical tanks which are torsionally stabilized by flexible catenary production riser and export riser bundles, and serviced by separate catenary pipe bundles. Piles are secured to the seabed, each pile assembly being pivotally connected to a lower rigid tendon, which is in turn connected to tendons arranged about the periphery of the interconnected cylindrical tanks.

Abstract: For use with a subsea well incorporating an external conductor pipe extending upwardly above the seabed, a well support miniplatform is set forth. In the preferred and illustrated embodiments, the preferred embodiment describes a longitudinally split, flange equipped, bolt joined elongate conductor clamp supported on a frame at the bottom thereof and having a plurality of appended upstanding braces. The support frame is adapted to be rested on a seabed and held in place by a number of anchors driven into the seabed at corners. The support frame is selectively installed after completion of a well wherein the conductor pipe extends above the seabed. The support frame may subsequently be removed after installation of a permanent platform. In alternate embodiments, the support frame may be installed as a permanent structure. A boat landing and miniplatform may be mounted on the conductor pipe or the conductor clamp supported by the support frame.

Abstract: For use with a subsea well incorporating an external conductor pipe extending upwardly above the seabed, a protector apparatus is set forth. In the preferred and illustrated embodiment, the preferred embodiment describes a longitudinally split, flange equipped, bolt joined elongate conductor clamp supported on a frame at the bottom thereof and having a plurality of appended upstanding braces. The bottom frame is adapted to be rested on a seabed and held in place by a number of anchors driven into the seabed at corners. This apparatus is selectively installed after completion of a well wherein the conductor pipe extends above the bottom, and the apparatus is subsequently removed after protecting the pipe after drilling but before installation of a platform.
