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.
