Abstract There is disclosed a gravity anchor operable for use with a tethering system for securing a subsea based blow out preventer (BOP). In at least one embodiment, the anchor (15) comprises a weighted body (25) having a portion or region configured capable of supporting, at least in part, a tensioning system (30) configured for operable association with a tether attached to the BOP. The gravity anchor (15) further comprises a guard means (comprising, for example, guard elements 35A, 35B) associated with the weighted body (25) and configured so that a portion of the guard means is provided more distal of the body than a portion of the tensioning system (30) so as to reduce a risk of the portion of the tensioning system becoming subject to interference during handling of the gravity anchor (15). In another embodiment, a method of use of the described gravity anchor is also disclosed.
