Abstract
A spud is reciprocal through a well carried at the lower end of a reciprocal pole. The pole carries a crane at its upper end to control the vertical position of the spud, the distance between the upper face of the well and the crane being greater than the length of the spud to enable easy replacement of the spud. When the pole and spud are both lowered, up to their maximum extents, the spud can anchor a dredge barge in water having a depth substantially greater than the length of the spud.
