ABSTRACT:
A method and apparatus for securing a tubular element to the bottom of a body of water, comprising the steps of lowering the tubular element from the watersurface to the waterbottom, removably securing the pumping unit to the tubular element either before or after the lowering of the tubular element, closing the tubular element at the upper end, reducing the pressure within the tubular element by operating the pumping unit, so as to cause the tubular element to penetrate into the waterbottom to a desired depth. Subsequently, the operation of the pumping unit is stopped and the pumping unit is disconnected from the tubular element and raised to the watersurface to recover it.
