Patent ID: 8468966

Claim:
Anchor ( 1 ) comprising a fluke ( 10 ) which can be introduced into an anchoring ground ( 2 ) in accordance with a direction of penetration (P) by exerting a pulling force (F) on an anchor line ( 4 ) connected to the anchor, and a measuring coupling ( 50 ) which during introduction of the fluke forms part of a force transfer between the anchor line and the fluke, wherein the measuring coupling ( 50 ) is provided with a first coupling member ( 31 ) that is connected to the fluke, a second coupling member ( 52 ) that is connected to the anchor line ( 4 ), a hollow coupling bar ( 54 ) 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 ( 60 ) extending through the hollow coupling bar and which at least at its ends ( 63 , 65 ) is connected to the coupling bar in order to deform along with the coupling bar, wherein the measuring body ( 60 ) is provided with deformation sensors ( 80 ) for recording deformation parameters of the measuring body.
