Abstract: The subsea support system includes a suction pile installed underwater without a remote operated vehicle (ROV). A drilling rig or offshore windfarm can be anchored by the suction pile in relatively shallow water with reduced equipment and costs. The system includes a suction pile, a vent valve assembly made integral with the suction pile, and an installation tool assembly removably attached to the vent valve assembly by a clamping device. The system is connected on a vessel before being deployed. Once lowered to the subsea location, the installation tool assembly actuates a seal plate to positions corresponding to closing the suction pile, pumping water through the vent valve assembly to embed the suction pile, and sealing the suction pile at the desired depth. The installation tool assembly can be released by the clamping device to separate from the vent valve assembly and return to the vessel for reuse.

Abstract: The disclosure describes, in part, battered composite piles arranged in-line with angled legs of a tower (e.g., lattice tower). The number of battered composite piles may be equal to the number of angled tower legs of the tower, and each of the battered composite piles may attach to a respective angled tower leg and may have batter angles at angles that match an angle of the angled legs of the tower. These battered composite piles are loaded predominantly axially rather than in shear and, thus, the piles may be designed to be much smaller in size while still meeting safety requirements. In addition, the piles may be installed in less time and at a lower cost than compression/lift and shear loaded foundations.
