A foundation pile comprising a longitudinal through hole (1) and a plurality of crosswise through holes (2) transverse to longitudinal through hole (1) extending between longitudinal through hole (1) and the outer surface of the pile and optionally further comprising check valves positioned in the crosswise through holes (2), configured such that the crosswise through holes (2) and the check valves allow one-way communication from the inside of the pile to the outside of the pile from longitudinal through hole (1) to the outer side surfaces of the pile.

A modular foundation support system includes modular foundation support components including shafts provided with integrally formed coupler features on their respective distal ends. The coupler features are configured with a non-uniform wall thickness defining a plurality of sections of respectively different diameter to matingly couple the shafts to one another in a torque transmitting relationship. The coupler features may be integrally formed and fabricated on the distal end of each respective shaft.

A system for a batter piling guide including a base plate assembly and a level assembly is disclosed. The base plate assembly includes a base plate with a top portion and a bottom portion. The top portion includes a slit that has notches at predetermined locations. A level of the level assembly is secured to the base plate with fasteners. The fasteners are slidable within the slit and secured at desired notches that correspond with a desired angle. The angle setting is monitored for batter piles being driven into a ground surface. The base plate and level are in abutting contact with the batter piles and the desired angle remains constant if the batter pile is being driven properly.

A method of installing an upright elongate hollow subsea foundation that is higher than it is wide, such as a suction pile. The foundation is at least partially embedded in seabed soil. A partition layer is placed within the foundation, for example by injecting a grout, supported by a plug of soil that is surrounded by the foundation. The partition layer is placed on the plug of soil at a level that is spaced from the top of the foundation by at least 20% of the height of the foundation. Above the partition layer, the interior of the foundation may be filled with water and/or a rigid body, such as a solid mass or a hollow liquid-filled tank.

A grout plug assembly for use in forming a pipe pile system defining at least one pile assembly inner surface portion comprises a resiliently deformable plug body defining a plug outer surface, a plug inner surface, a first plug end surface, a second plug end surface. The plug inner surface defines a plug passageway. The plug outer surface is sized and dimensioned to engage the at least one pile assembly inner surface portion of the pipe pile system during formation of the pipe pile system.
