<p>The invention relates to a riser weak link in a riser connecting a floating installation or vessel to a hydrocarbon well on the seabed, said weak link comprising a first riser part (71) in the form of an upper housing (73) for connecting to a riser upper section (74); a second riser part (72) in the form of a lower housing (75) for connecting to a riser lower section (76), wherein one riser part is arranged to extend into the other riser part; and connection devices for releasably connecting the upper and lower housings (73, 75). The weak link comprises a first connection device (81 ) arranged to fail if a tensile force on the first and second riser parts (71, 72) exceeds a first threshold force, and that the weak link comprises a second connection device (82) arranged to fail if a compressive force on the first and second riser parts (71, 72) exceeds a second threshold force.</p> |
