Abstract
Offshore well drivepipe or caisson may be supported by a skeletal frame type supported having spaced apart caisson receiving guide sleeves and spaced apart sets of pile guide sleeves interconnected by lateral and diagonal brace members. The support may be totally submerged and sleeved over the caisson while resting on the seabed and secured thereto by conventional piles which are installed through the pile guide sleeves and driven to temporary or permanent depth. The support structure provides a low-cost, reusable, temporary or permanent support for well caissons or drivepipes.
