Abstract
Piles are driven underwater by feeding them through spaced apart, aligned, tubular guides mounted on a structure to be anchored by the piles. When the piles reach the sea bed an elongated follower is fed down through the guide sleeves to the top of the piles. A compressible fluid driven hammer is arranged to drive against the upper end of the follower which in turn drives the pile. The submerged depth of the hammer at the upper end of the follower is less than it would be at the top of the pile and accordingly the exhaust pressure at the hammer is minimized and the hammer effectiveness is enhanced.
