Abstract: A method of installing a plurality of pin piles into a seabed including at least the steps of: (a) lowering a pin pile apparatus comprising a first pin pile and an attached clump weight towards the seabed; (b) allowing the first pin pile to self-penetrate the seabed based on self-weight of the pin pile apparatus and the momentum from step (a) until the clump weight reaches the sea bed; (c) disconnecting the clump weight from the first pin pile; and (d) recovering the clump weight for use with a second pin pile and repeating steps (a)-(c). In this way, the pin piles are easily installed from their descent to the seabed with the clump weight, which can then be removed and applied to the next pin pile in an easy and repeatable operation without requiring a suction apparatus or hammer or drill.
