Abstract: Apparatus and method is disclosed for filling the annulus between the jacket and piling of members of cluster or pin piles with fluid grouting material. Cluster or pin piles surround and support a main leg can of an offshore rig. The main leg extends to the water surface and supports the platform of the rig. The cluster or pin piles terminate below the water surface. Each cluster or pin pile includes a hollow, cylindrically shaped jacket with a piling through it. A dual packer, comprising two, vertically separated packers is used to seal the jacket of the cluster or pin pile to the piling. An annular chamber is formed between the two packers. Dual lines provide fluid flow communication between the annular chamber and apparatus located at the water surface. The apparatus at the water surface uses the dual lines to exhaust water from the annular chamber and set the packers.
