ABSTRACT:
A method of erecting a marine structure at an offshore site of a body of water. The structure has a plurality of hollow tubular members associated with it. Examples of such members include skirt piles, conductors, legs, etc. The bottom portion of at least some of the members is sealed by a watertight removable plug with each plug provided with a plurality of normally closed vents. The vents, when opened, permit the pressure on both sides of the removable plugs to become substantially equal. After the structure is transported to the site, the tubular members are oriented substantially vertically with the bottom portion of the members extending downwardly. The structure is then submerged, preferably the bottoms of the tubular members engage the bottom surface of the body of water at the site. The vents in the plugs are opened, and after the pressure on both sides of each removable plug is substantially equal, the plugs are disconnected from the tubular members and are removed through the tops of their respective members by wire ropes to clear the interior of each of the members. Piling can then be driven to secure the structure to the bottom of the body of water.
