Vibration Embedment Anchor

Navy has developed a vibration embedment anchor for use in shallow or deep water. The vibrator drive unit uses two counter-rotating eccentric masses to develop the vibrational force applied to the anchor fluke. The vibration unit can be either electrically or hydraulically powered and the vibrator and support frame can be recovered after the anchor is installed. The present system uses a Y-fluke that penetrates the sediment in a low-profile configuration and is keyed by pulling back on the anchor line to develop maximum breakout resistance. The support platform uses remote sensing to determine the
