A method is for supporting a retaining wall that includes a number of wall blocks positioned to retain material against a rear side of the plurality of wall blocks. The method includes attaching the rear side of at least one of the wall blocks to at least one ground-stabilizing base body supporting the wall blocks. Kits and systems are also disclosed.

An excavating pump apparatus and a pile installation apparatus having the same are disclosed. An excavating pump apparatus in accordance with an embodiment of the present invention may include: an excavation head being inserted into an inner space of a pile through an open hole opening the inner space of the pile and being configured to crush seafloor sediments and allow the crushed seafloor sediments to be flowed therein; an outlet conduit connected to the excavation head and being a channel for discharging the seafloor sediments flowed into the excavation head to an outside of the pile; and a pump configured to move the seafloor sediments through the outlet conduit by providing a pump pressure to the outlet conduit

A system for joining two separate spun piles by interlocking together a top end plate located at a bottom end of a first spun pile to a bottom end plate located at a top end of a second spun pile, wherein the end plates each have a plurality of segments comprising an equal number of segmental protrusions and segmental recesses.

A foundation system for the foundation of an offshore structure includes a monopile having an anchoring portion anchorable in a seabed and a connection portion disposed at the opposite end. A platform structure is connected directly to the connection portion of the monopile or indirectly via a transition piece. The platform structure is disposable above a water surface. The foundation system includes at least two stabilizing devices connected directly to the platform structure or indirectly to the platform structure via the transition piece. The stabilizing devices are attachable to the seabed such that tensile forces or compression forces are transmittable between the seabed and the platform structure. Securing points on the stabilizing devices, together with the connection portion of the monopile, define a plane having a horizontally extending component.

An anchoring system using hollow piles connected with a cap, the hollow piles open at the top and closed at the bottom. A skirt extends from the cap. In use, the anchoring system is lowered to an ocean floor and a suction element removes water and ocean floor material from under the cap to lower the anchoring system into the ocean floor. Flexible walls at closed ends of the hollow piles may provide pressure differentials separating the undersea pressure to which the interiors of the hollow piles are exposed from air chambers at the closed ends of the piles at substantially lower pressures.
