AN EXPLOSIVE DRIVEN ANCHOR FOR SECURING A SUBMARINE PIPELINE
An explosive driven anchor for securing a submarine pipeline to the bottom of a body of water comprises a gun barrel having a closed upper end and provided with an internal sliding piston, a cylindrical projectile integral with the piston, a means for driving the projectile from the barrel at a high velocity, and a mechanical device within the barrel for permitting the projectile to travel down in the barrel at a decelerating rate other than an abrupt stop when the projectile has protruded a predetermined distance from the barrel. It is especially useful for anchoring pipelines at the bottom of bodies of water having a substantial current, such as Cook Inlet, Alaska.
