Abstract
An anchor (3) and an anchor positioning system (1) are provided in which an anchor shackle (7) is arranged such that, in use, it is disposed within a chasing collar (17). The anchor shackle can be positioned in a locking position in the chasing collar in which rotational movement of the anchor shackle around its longitudinal axis is inhibited. The anchor shackle may also be positioned in an unlocked position in the chasing collar. The anchor shackle can rotate around its longitudinal axis (x-x) from the unlocked position to the locking position. Accordingly, the anchor shackle assists in maintaining the anchor (3) in a desired orientation corresponding to the locking position.
Claims26
An anchor positioning system, comprising:
- an anchor shackle for an anchor, the anchor shackle having a longitudinal axis;
- and
- a chasing collar arranged to receive the anchor shackle in a locking position in which rotational movement of the anchor shackle around the longitudinal axis is inhibited, the chasing collar further being arranged to receive the anchor shackle in an unlocked position;
- wherein the anchor shackle can rotate around its longitudinal axis from the unlocked position to the locking position.
An anchor positioning system, comprising:
- an anchor shackle for an anchor;
- and
- a chasing collar for receiving the anchor shackle;
- wherein the chasing collar is suitable for receiving the anchor shackle in a locking position in which rotational movement of the anchor shackle is inhibited.
A chasing collar for receiving an anchor shackle of an anchor, the chasing collar comprising:
- attachment means for attaching a chasing line;
- and
- a keyed portion cooperable with the anchor shackle to inhibit rotational movement of the anchor shackle.
An anchor shackle for an anchor, the anchor shackle comprising a keyed portion cooperable with a chasing collar to inhibit rotational movement of the anchor shackle.
A method of positioning an anchor, comprising:
- locating an anchor shackle of the anchor in a locking position in a chasing collar;
- guiding the anchor to a desired location using a chasing line attached to the chasing collar;
- wherein
- tension is maintained in the chasing line to retain the anchor shackle in the locking position and thereby to inhibit rotational movement of the anchor shackle.
An anchor comprising:
- an anchor shackle;
- and
- an anchor body pivotally mounted to the anchor shackle,
- wherein pivotal movement of the anchor body relative to the anchor shackle is limited to ensure that the center of gravity of the anchor remains offset from a first surface of the anchor shackle in a given direction.
