Problems solved by technology

In such cases, permanent or semi-permanent installations are usually used, such as large and correspondingly heavy concrete blocks, which are left in place when they soon become unsuitable or no longer needed Prove to be difficult or impossible to retrieve, thereby potentially rendering shipping dangerous

Embodiment Construction

[0020] First refer to figure 1 , generally shown at 1, comprises a flat anchor body 2 of general length and an associated 3-branched rope 3 having a central rope 4 and respective opposing outer ropes 5 . In use, the anchor body is designed to remain approximately horizontal during and after deployment, while remaining vertically suspended from the anchor line rope only during descent and recovery.

[0021] The main body of the anchor body 2 is constructed of metal or other structural layers and includes one or more downwardly directed grooved open spikes or claws 6a and 6b at each end, using the spikes or claws 6a and 6b Sand or mud eg from the sea floor is drilled and funneled away from the sea floor (not shown).

[0022] The claws are permanently and firmly attached to the horizontal backplate of the anchor body, and thus act as an integral structural element imparting longitudinal bending stiffness to the anchor body. At each end of the anchor body 2, a ("V" shaped as in ...

Abstract

Anchor apparatus (1) including an anchor (2) and a slideable anchor bridle (3), the anchor having a lower part or body portion with oppositely disposed anchoring formations (6a,6b) extending therefrom and an upper part including bridle attachment means in the form of at least two parallel bridle rails extending above and between the oppositely disposed anchoring formations (7,8), limbs (4,5) of the anchor bridle being slideably attached, in use, to respective bridle rails (7,8), the arrangement being such that when deployed, the anchor can be pulled in one direction whereby to permit one of the oppositely disposed anchoring formations to penetrate the sea bed and whereafter if and when the anchor is pulled in the opposite direction after the bridle limbs have slid along the bridle rails, the other of the oppositely disposed anchoring formations also penetrates the seabed, whereafter the anchor can continue to be pulled in successively alternate directions via the bridle to penetrate progressively further into the sea bed until firmly fixed therein.

Description

technical field [0001] The present invention relates to anchors for permanent or temporary mooring of floating objects such as ship hulls and buoys in water such as tidal estuaries. But the invention is not limited to this use. Background technique [0002] A conventional anchor body for boats and other large vessels or floating devices includes one or more flukes pivotally mounted on one end of an elongated shank having an eyelet on the other end of the elongated shank, The shank may be connected through the eyelet to eg the end of an anchor line which itself is connected at its other end to a winch on a moored vessel or anchor tug. When the anchor body is lowered to the seabed or river bed, the anchor body is dragged along a very shallow angle for a correspondingly large length of anchor line or chain (the maximum length is typically about three times the water depth) to allow The or each fluke drills into the sea floor and thereby assists the vessel in anchoring at a su...
