ABSTRACT:
An underwater template has one or a plurality of pile housings through which piles are driven into the earth at the floor of the water to fix the template in place by forging the pile into grooves in the housing. The forging operations are performed by a rotary cold forge tool with expansible rollers, the tool being rotatable by a running string of drill pipe guided by a swivel which lands on and is centered by the pile, or the forging is done by explosives confined between seals within the pile section.
