Anchoring device

An anchoring device for a floating installation to which the device is connected by an anchoring line, the device comprising:

• an assembly of at least two plowshare anchors wherein each anchor includes an interior part of a shape facilitating penetration into ground and a posterior part, each anchor including a dihedron having an upper edge with a front portion;
• at least two rigid shanks having an axis and first and second ends, each shank being connected at its first end to one of the dihedrons by a rigid strut extending upwardly from a location adjacent to both the upper edge and the posterior of the dihedron, the shanks being disposed in an orientation wherein the plane passing through the front portion of each upper edge of the dihedrons and the second end of the shanks define with the axis of each shank an angle in the range of about 15.degree. to about 35.degree.;
• an anchoring plate rigidly fixed to the shanks and extending therebetween at a location adjacent to the second ends of the shanks;
• the anchoring plate having a pair of exposed, parallel surfaces which are substantially parallel to the upper edges of the dihedrons, and the anchoring plate having a leading edge defined by a plurality of teeth, and
• means disposed at both ends of each shank for attaching anchor lines.
