ABSTRACT:
A system for placing piles into the seafloor by using pressure differential as the driving force. The pressure differential is created by a pump unit located either within or external to the pile. Operation of the pump unit which displaces both water and soil across a bulkhead section, enables the pile to be driven into and under the seafloor. A section of piling with a pump unit can operate as an uplift anchor, and multiple pumps on a large diameter piling can be embedded into the seafloor as a large foundation.
