<p>An activation mechanism to release a guidepost (1) from a seabed structure (not shown) is described. The guidepost (1) includes a tubular main body (1a), an operating means (2) at the upper end of the main body, a locking mechanism (3) at the lower end of the main body to enable attachment to the seabed structure, and an interconnecting device arranged inside the tubular main body (1a), and connecting the operating means (2) to the locking mechanism (3) in order to be able to activate the locking mechanism (3) from the top of the guidepost (1), as required. The operating means (2) includes a rotatable outer sleeve (2a) which is able to transform a rotary motion to either a lifting or lowering motion of the interconnecting device, which in turn either elevates or lowers an activation means (4a) that influences on at least one locking pawl (3a) to be pulled inwards beyond the diametrical dimension (D) of the guidepost (1) in order to release an engagement with a groove or ledge on the seabed structure.</p> |
