Abstract : The patent relates to a propellant-actuated direct embedment anchor which utilizes simplified structural shapes and provides a rapid keying feature which allows the most efficient use of penetration energy. The anchor system has two major parts; a launch vehicle and a projectile which include a piston and fluke. Two different fluke designs are provided to satisfy the realm of anticipated seafloor conditions (sand, clay, and rock). The flukes designed for sand and clay are similarly configured plate-like projectiles which only differ in length. The fluke designed for rock anchoring is a three-fin, arrowhead-shaped projectile, specially configured to penetrate rock and resist a specified pull-out load. The launch vehicle consists of a launching system, a reaction vessel and a firing mechanism. The firing mechanism is comprised of a weighted touch-down rod with a square base pad and a safe-and-arm device. The sand and clay flukes use a quick-keying design to maximize efficiency and holding power after embedment.
