<p>A riser weak link in a riser connects a floating installation or vessel to a hydrocarbon well on the seabed. The weak link includes a first riser part in the form of an upper housing for connecting to a riser upper section; a second riser part in the form of a lower housing for connecting to a riser lower section, wherein one riser part is arranged to extend into the other riser part; and connection devices for releasably connecting the upper and lower housings. The weak link includes a first connection device arranged to fail if a tensile force on the first and second riser parts exceeds a first threshold force, and that the weak link includes a second connection device arranged to fail if a compressive force on the first and second riser parts exceeds a second threshold force.</p> |
