Moorings for offshore installations

A mooring arrangement, comprising:

• at least two outer anchors;
• and
• a reaction anchor disposed between the outer anchors and configured to react against outward forces applied by tension in at least two anchor legs that extend outwardly from the reaction anchor to the outer anchors;
• wherein each anchor leg comprises a tensioner, an inner line extending from the reaction anchor to the tensioner, and at least one outer line extending from the tensioner to at least one of the outer anchors, and wherein the outer anchors comprise at least one drag anchor that is configured to self-embed upon being dragged toward the reaction anchor.

A method of installing a mooring arrangement, the method comprising:

• fixing a reaction anchor at a seabed location;
• connecting at least two anchor legs to the reaction anchor, each anchor leg radiating from the reaction anchor across the seabed and terminating outwardly in at least one outer anchor such that the reaction anchor is disposed between the outer anchors;
• imparting tension in the anchor legs to pull the outer anchors inwardly toward the reaction anchor;
• and
• mooring a floating body with at least one mooring line extending upwardly from each anchor leg.
