At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.
