Abstract
A spar hull centerwell arrangement wherein an adjustable buoyancy centerwell device (ABCD) is disposed within the centerwell of the structure. The adjustable buoyancy centerwell device is rigidly connected to the interior walls of the hard tank and defines an adjustable buoyancy centerwell device within the centerwell. The adjustable variable buoyancy unit is a water and airtight buoyancy chamber that allows the interior ballast to be changed as required. This device can also be used as a storage unit for on board fluids and other produced hydrocarbons.
