A lead for installing a pile into a seabed floor comprising: an elongated body extending longitudinally along a first axis in a first direction from a top end to a bottom end and configured to receive a pile oriented in the first direction; and a lead indexing foot attached to the bottom end of the elongated body and laterally offset with regard to the first axis.

A sheet piling filler-corner member includes one or more female couplings for engagement of male couplings of connected sheet pilings, and one or more male coupling members for engagement within female couplings of connected sheet pilings. Selective attachment of sheet pilings using the filler-corner member, and/or modification of the filler-corner member into different configurations allows the filler-corner member to universally function as a spacer or filler for adding length to a sheet piling assembly, as a corner coupling, or as a gender-change adapter between sheet pilings.

A king pile for a combined wall system includes a first flange, a second flange, and a web. The first flange has a first flange body that is a generally rectangular plate having a first edge, a second edge, and a face. A first king pile interlock is formed integrally with the first flange body at the first edge, and a second king pile interlock is formed integrally with the first flange body at the second edge. The king pile includes a second flange having a second flange body, the second flange body being a generally rectangular plate having a face. The king pile also includes a web. The web may be a generally rectangular plate that is coupled to the face of the first flange body and the face of the second flange body. The first flange, second flange, and web may be formed separately and coupled by welding.
