Field testing of a reduced scale dynamically embedded plate anchor
Field testing of a reduced scale dynamically embedded plate anchor
The dynamically embedded plate anchor (DEPLA) is a rocket-shaped anchor that penetrates to a target depth in the seabed by using kinetic energy obtained through free fall and by the anchor’s self-weight. After embedment, the central shaft is retrieved leaving the anchor flukes vertically embedded in the seabed. The flukes constitute the load bearing element as a plate anchor. This paper presents initial field data from a series of tests using a 1:20 reduced scale anchor in a lake underlain by very soft clay. Results indicate that the DEPLA exhibits similar behaviour to other dynamically installed anchors during installation, but with much higher capacities, up to 27 times the dry weight of the anchor.

Abstract
The dynamically embedded plate anchor (DEPLA) is a rocket-shaped anchor that penetrates to a target depth in the seabed by using kinetic energy obtained through free fall and by the anchor’s self-weight. After embedment, the central shaft is retrieved leaving the anchor flukes vertically embedded in the seabed. The flukes constitute the load bearing element as a plate anchor. This paper presents initial field data from a series of tests using a 1:20 reduced scale anchor in a lake underlain by very soft clay. Results indicate that the DEPLA exhibits similar behaviour to other dynamically installed anchors during installation, but with much higher capacities, up to 27 times the dry weight of the anchor.
