Patent ID: 11932353

Abstract:
A hydraulic piston spud pole for anchoring a vessel may comprise an elongate sleeve having a top, a hydraulic inlet, and a bottom terminating in a bottom aperture, a portion of the elongate sleeve being formed to contain a hydraulic column; a spud pole having a piston vertically-movably seated within the elongate sleeve; and a pump assembly connected to the hydraulic inlet that is preferably activated by a controller to lift or drop the spud pole. The elongate sleeve may comprise a vertically-extending inner surface and a sleeve bearing, and the spud pole may comprise a vertically-extending outer surface configured to fit closely against the sleeve bearing while the piston fits closely against the elongate sleeve's vertically-extending inner surface. The hydraulic column may be defined between the vertically-extending outer surface of the spud pole, the vertically-extending inner surface of the elongate sleeve, the piston, and the sleeve bearing.
