Claims18
An auxiliary off-shore column located near a working column or platform for sea-bed exploitation, said auxiliary column being pivotally connected with its submerged lower part to a base member resting on the sea bottom whereas its emerged upper part comprises preferably at its top a landing area for instance for helicopters, said submerged lower part comprising a main float for keeping said auxiliary column in an at least approximately vertical position, wherein the improvement consists in that said auxiliary column is fitted up at least in part between its top and the main float with dwelling rooms, living quarters or like accommodation facilities for the staff on duty on said working column or platform and in that there are means for providing an at least temporary communication between both columns with a view to transferring said staff, said communication means comprising a footbridge connecting said fitted-up part to said working column or platform, said footbridge comprising at least two elements pivotally connected in series to each other, said footbridge being supported at an intermediate point thereof by means of a float device, the overall length of both elements being higher than the greatest distance separating, at its level, the dwelling column from the working column or platform.
An auxiliary off-shore column located near a working column or platform for sea-bed exploitation, said auxiliary column being pivotally connected with its submerged lower part to a base member resting on the sea bottom whereas its emerged upper part comprises preferably at its top a landing area for instance for helicopters, said submerged lower part comprising a main float for keeping said auxiliary column in an at least approximately vertical position, wherein the improvement consists in that said auxiliary column is fitted up at least in part between its top and the main float with dwelling rooms, living quarters or like accommodation facilities for the staff on duty on said working column or platform and in that there are means for providing an at least temporary communication between both columns with a view to transferring said staff, said communication means comprising a footbridge connecting said fitted-up part to said working station or platform, and wherein said footbridge is shorter than the least normal distance, at its level, between the dwelling column and the working column or platform, said working column or platform comprising a means for artificially and forcibly tilting the dwelling column towards said working column or platform and in that the footbridge is carried by one of both columns and is bearing upon the other column in the inclined position of the dwelling column.
An auxiliary off-shore column located near a working column or platform for sea-bed exploitation, said auxiliary column comprising a shaft with a top end emerging from the sea and a bottom end located near the sea bottom defining thereby an emerged upper part and a submerged lower part, the bottom end being pivotally connected to a base member resting on the sea bottom whereas the top end comprises preferably a landing area for instance for helicopters, the submerged lower part comprises a main float for keeping the shaft in an at least approximately vertical position, wherein the improvement consists in that said auxiliary column is fitted-up at least in part between its top end and the main float with dwelling rooms, living quarters or like accommodation facilities for the staff on duty on said working column or platform and in that there are means for providing an at least temporary communication between both columns with a view to transferring said staff.
