Abstract: An elongated deck section having two rows of legs with several legs per row is fabricated with the legs hingedly mounted on footings adapted to receive fluid bearings and is transported from the fabricating yard to a dock head over a smooth concrete slab of minimal slope and thence longitudinally via fluid bearing adapted gang planks and tracks onto and along a barge disposed with its stern adjacent the dock head and grounded thereat, the platform being transported by placing fluid bearings under the footings which allow the section to be moved sideways, lengthways, or rotated or turned, as desired, the deck's horizontal truss stresses and the fluid bearing loads being controlled by actuating fluid elevators between each leg and the fluid bearing thereunder, the barge being initially ballasted so that change of ballast during loading is unnecessary to maintain minimal slope of the barge, the section then being anchored to the barge and the barge reballasted to float its stern and trim the barge preparatory to
