PURPOSE: A marine pile supported foundation construction method is provided to minimize the effect of marine weather conditions which affect the operation of marine equipment and the construction environment. CONSTITUTION: A marine pile supported foundation construction method comprises the following steps. A barge (100) is moved after a pile (200) is vertically fixed in the hollow of the barge (a). The barge is fixed on an installation position after the pile and the barge are towed into the installation position (b). The pile is descended through the hollow of the barge to the seabed to support the barge (c). The seabed which is contacted with the end of the pile is drilled from the end of the pile by a drilling machine; and the load of the barge makes the pile to be pressed in for penetrating the seabed (d). The barge is towed to be removed from the pile after pressing the pile in the seabed; and the marine pile supported foundation is constructed.
