ABSTRACT:
A motion absorbing docking assembly for use in subsea docking operations. A tubular docking pile receives a pile head assembly in which a retractable pile head is positioned. When the pile head is impacted by a docking guide on a jacket being lowered into place, axially spaced shock cells having a common central support member absorb the relative motion between the pile head and the docking pile. This arrangement provides for absorption of twice the distance that each individual shock cell is capable of absorbing by itself.
