Vibratory Embedment Anchor System.
Abstract
A requirement existed for an anchor especially suited for deep ocean work. Conventional anchors are designed for placement by dragging and have low efficiency in resistance to uplift forces which makes these anchors impractical for use in ocean depths greater than 500 feet. An anchor that can penetrate vertically into the ocean bottom and develop a high capacity to resist uplift and horizontal loads relative to its own weight is required for active and contemplated ocean tasks. The aim of this project was to meet this requirement by developing and testing a vibratory type of anchor similar in principle to commercial vibratory pile hammers and vibrating core samplers now in use. It has been our intention to develop an anchor of this type that would offer advantages in weight control, versatility, and safety over an anchor embedded with a single phase burst of energy and also in placement, performance and economy of material over a conventional anchor.
