<p>A marine anchor for mooring an object e.g., ship, oil rig etc. to the sea bed comprises a fluke (2) with a shank (3) attached to the fluke. To enable the anchor to orientate on the sea bed from an inverted position to an upright working position, trigger elements in the form of auxiliary flukes (23, 24) are supported by respective lugs (21, 22) upstanding from the fluke on either side of the anchors vertical plane of symmetry (S-S). The auxiliary flukes (23, 24) extend laterally from the lugs (21, 22) and are inclined at an acute angle (β1) to the main fluke (2). The anchor includes support means (4) arranged such that when the anchor lies inverted on a firm sea bed one of the auxiliary flukes (23, 24) is located in position for digging in when the anchor is pulled forwardly. Anchor orientation is achieved by the anchor tilting about the lug in auxiliary fluke (23, 24).</p> |
