Abstract: An anchor has a fluke, a shank that is connected to the fluke, a coupling to attach the fluke to an anchor line or anchor chain, and an angle adjustment provision to adjust the angle between the shank and the fluke, wherein the angle adjustment provision is a hinge between the fluke and the shank, a first positioning member connected to the shank that is provided with a series of first positioning holes at a first intermediate distance and a second positioning member connected to the fluke that is provided with a series of second positioning holes at a second intermediate distance and spaced apart from the hinge axis, and a positioning pin that is inserted in one of the aligned first and second positioning holes, wherein the second intermediate distance differs from the first intermediate distance.

Abstract: Disclosed is an anchor having a fluke, a shank that is connected to the fluke, and a coupling to attach the fluke to an anchor line or anchor chain, wherein the shank has two shank legs each having a straight shank plate with an outer surface that extend on the opposite sides of the plane of symmetry of the anchor and that diverge from the coupling towards the fluke, wherein the fluke has two straight penetration plates with a top surface on the opposite sides of the plane of symmetry of the anchor, wherein the orientation of the outer surfaces with respect to the top surfaces is specified by three angles under narrow ranges to provide excellent penetration properties and an excellent holding capacity.

Abstract: An anchor assembly (1) comprises a plate anchor element (2) mounted on an associated dynamic implanting follower (6) to facilitate dynamically embedding the plate anchor element (2) in a mooring bed below a body of water. The plate anchor element (2) has a tubular sleeve (20) which is slidably mounted on a shaft (8) of the implanting follower (6), and locates at an upper end of the implanting follower (6) which has a pointed penetrating tip (9) at a lower end of the shaft (8). Radial flukes (22) are mounted on the sleeve (20) in a cruciform configuration. A through-hole (3) is provided in one of the flukes (22) for attachment of a tether line. For deployment of the plate anchor element (2) the anchor assembly (1) is dropped from a height above the mooring bed, freefalling through the water and penetrating into the mooring bed. The implanting follower (6) is then retrieved leaving the plate anchor element (2) buried in the mooring bed.

Abstract: Anchor comprising a fluke which can be introduced into an anchoring ground in accordance with a direction of penetration by exerting a pulling force on an anchor line connected to the anchor, and a measuring coupling which during introduction of the fluke forms part of a force transfer between the anchor line and the fluke, wherein the measuring coupling is provided with a first coupling member that is connected to the fluke, a second coupling member that is connected to the anchor line, a hollow coupling bar that couples the coupling members to one another, wherein the coupling members in the longitudinal direction of the bar engage onto the coupling bar at different places in order to be able to deform it, and a measuring body extending through the hollow coupling bar and which at least at its ends is connected to the coupling bar in order to deform along with the coupling bar, wherein the measuring body is provided with deformation sensors for recording the deformation parameters of the coupling bar.
