The present invention provides an apparatus for aligning an integrated deck carried on a barge with a jacket secured to the seafloor. The apparatus comprises a plurality of cantilevered springs extending vertically downward from the deck and a plurality of sockets secured to the jacket, each socket being positioned to receive the lower end of one of the cantilevered springs. As the cantilevered springs are lowered into the sockets, wind or wave induced horizontal motion of the deck is accommodated by tilting of receiving members in the sockets. Once the cantilevered springs are fully engaged with the sockets, the receiving members no longer tilt and the great stiffness of the cantilevered springs permits only very slight horizontal motion of the deck so that the barge can be ballasted downward to transfer the deck load to the jacket without misalignment. |
