Abstract
The present invention describes an extraction system () for expediting removal of a footing () that is embedded in a seabed or marine floor. The extraction system provides a supply of pressurized fluid () to a chamber from where the pressurized fluid exudes through porous members (, etc) located on the base () of the footing (). When an uplifting force is applied to the footing () for its removal, the pressurized fluid () exudes out through the porous member (, etc.) to compensate or reduce suction induced beneath the footing, without fluidizing or channeling of the seabed soil, thereby expediting removal of the footing ().
