A torpedo anchor is a type of power penetration anchor, usually about 15 meters long and weighing up to 130 tons. The shape of the anchor itself is similar to that of a torpedo, so it is called a torpedo anchor. Torpedo anchors can be divided into two types: those with a tail fin and those without. Anchors with a tail fin usually have four tail fins. The torpedo anchor is cylindrical in shape, hollow inside, and can be filled with high-density materials such as concrete and scrap metal to increase its own weight and lower the center of gravity of the anchor to maintain its stability. The lower end is conical in shape, which is convenient for penetration into the seabed soil.
Torpedo anchors are quick and easy to install. No external force is needed during installation. Just release them vertically at a sufficient height from the seabed, allowing them to fall by their own gravity. When they collide with the seabed, they will penetrate the seabed to a certain depth by the huge inertial force caused by high acceleration.
