A marine anchor (1, 40, 40A, 40B, 40C) for deep embedment in a seabed soil (2) including a fluke member (4, 41) and a shank member (7, 49) and means (12, 62, 62A) for constraining a load application point thereon (13, 15, 63, 63A, 65) to lie in first and second directions from a centroid (9,46) of said fluke member (4, 41) forming, with respect to a fore-and-aft direction (10, 47) of the fluke member (4, 41), an acute forward-opening angle (A) and an acute rearward-opening angle (C) respectively whereby said marine anchor (1, 40, 40A, 40B, 40C) can be pulled rearward to bury deeply in a rearward direction (R) after having been pulled forward to bury deeply in a forward direction (F). |

1. An anchor for embedment in a soil below a seabed surface comprising:
a fluke member having substantially planar upper surfaces which bear on said soil when said is subjected to loading therein, said planar upper surfaces having a centroid located in a plane of symmetry of said anchor; a shank member; at least two load application points for attachment of a connecting member for connecting said anchor to an anchor line; and a passageway for enabling said connecting member to be transferred between said load application points such that said load application points lie on a substantially straight line which contains the centroid of said planar upper surfaces and forms an angle of inclination with a reference straight line of said anchor, located in said plane of symmetry and parallel to said planar upper surfaces, said reference straight line containing said centroid and defining a forward and a rearward direction of said anchor, and such that said passageway is fixed angularly with respect to said reference straight line, characterised in that said angle of inclination is a forward-opening acute angle with respect to a first load application point and a rearward-opening acute angle with respect to a second load application point whereby loading applied by said anchor line via said connecting member to said anchor at a load application point causes said anchor to bury deeper below said seabed surface in a forward direction with respect to said first load application point and in a rearward direction with respect to said second load application point. |
