Abstract: A weak link (17, 43) for a riser system comprising a pin (2, 25) and a box (1, 24), bolts (11, 34) for releasably connecting the pin (2, 25) and the box (1, 24), the bolts being designed to break at a predefined tension. The link further comprising a pressure balancing mechanism for balancing axial forces acting on the bolts (11, 34) due to end cap effect. The weak link also comprises a strong mode mechanism and a dampening mechanism.

Abstract: An activation mechanism to release a guidepost from a seabed structure is described. The guidepost includes a tubular main body, an operating mechanism at the upper end of the main body, a locking mechanism 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, and connecting the operating mechanism to the locking mechanism in order to be able to activate the locking mechanism from the top of the guidepost. The operating mechanism includes a rotatable outer sleeve configured to transform a rotary motion to a lifting or lowering motion of the interconnecting device, which in turn elevates or lowers an activation mechanism that influences on at least one locking pawl to be pulled inwards beyond the diametrical dimension of the guidepost to release an engagement with a groove or ledge on the seabed structure.
