Plate Earth Anchor

Plate earth anchor :

--High capacity achievable.

- Resists uplift as well as lateral loads, enabling short scope moorings.

- Anchor dragging eliminated.

--Higher holding capacity to weight reaction than any other type of anchor.

--Handling is simplifed due to relatively light weight.

-Installation is simplified due to possibility of instantaneous embedment or seafloor contact.

(Propellant-embedded anchor.)

-- Accurate anchor placement possible.

--Does not protrude above seafloor.

-- Penetration is controlled and can be monitored. (Screw-in anchor; vibrated- in anchor; driven anchor.)

- Susceptible to cyclic load strength reduction when used in taut moorings in loose sand, coarse silt,seafloors.

--For critical moorings, soil engineering properties required.

--Anchor plate typically not recoverable.

-- Earth Anchor cable susceptible to abrasion/fatigue. (Propellant embedded anchor.)

- Surface vessel must maintain position during installation. (Screw-in anchor; vibrated-in anchor;driven anchor.)

--Operation limited to sediment seafloors. (Screw-in earth anchor; vibrated-in earth anchor.)
