ABSTRACT:
The method for re-deploying an offshore jacket using a plinth involves the steps of locating an offshore jacket; constructing a plinth with a plinth legs, a skirt pile sleeve, a mud mat, a space frame, guide cones, and a trestle per plinth leg; placing the plinth at the second site; driving one skirt pile into each skirt pile sleeve; disconnecting the jacket legs from the seabed at the first site; lifting the offshore jacket above the seabed; moving the offshore jacket from the first site to the second site; and lowering the offshore jacket such that each jacket leg stabs into each guide cone on the plinth until each jacket leg mud mat contacts each trestle; and inserting pin piles through each jacket leg and plinth leg and grouting the pin piles to effect a permanent structural connection between plinth and jacket.
