Abstract
A scissored sea-floor well template for positioning spacing of subsea wells or piling in the sea floor. Two arms, each having a pontoon template at each end thereof, are pivotally connected. The two arms are rotated about the pivot to a closed position for transportation to the marine site at which they are to be used. Inasmuch as the template is provided with pontoons, it can be towed and does not have to be loaded on a barge although it could be. Upon reaching the well site the arms are opened so that the pontoon templates assume the desired shape. The arms are then locked in this extended position and the scissor well template is then lowered to the ocean floor.
