Abstract

A riser connector assembly includes a first connector assembly portion with first locking members, a second connector assembly portion with second locking members, and a locking device with third and fourth locking members. The locking device is rotatably connected to the first connector assembly portion. The locking device rotates between a first position where each of the locking members are interlocked, a second position where the first and third locking members are interlocked, and the second and fourth locking members are not interlocked, and a third position where none of the locking members are interlocked, so that the locking device is removable. The first and third locking members selectively/releasably interlock via a relative rotation between the first connector assembly portion and the locking device. The second and fourth locking members selectively/releasably interlock via a relative rotation between the second connector assembly portion and the locking device.

Claims21

Dependent claims

A riser connector assembly for connecting a first riser section to a second riser section in an end-to-end relationship, the first riser section comprising an upper main tubular element and the second riser section comprising a lower main tubular element, the riser connector assembly comprising:

a first connector assembly portion comprising a first connector and first lugs arranged at regular intervals around a periphery of the first connector, the first connector assembly portion being attached to an end of the first riser section;
a second connector assembly portion comprising a second connector and second lugs arranged at regular intervals around a periphery of the second connector, the second connector assembly portion being attached to an end of the second riser section;
and
a locking device comprising an inner periphery, third lugs arranged at regular intervals around an upper portion of the inner periphery, and fourth lugs arranged at regular intervals around a lower portion of the inner periphery, the locking device being rotatably and releasably connected to the first connector assembly portion, the locking device being configured to rotate between:
a first position where the first lugs and the third lugs are interlocked, and the second lugs and the fourth lugs are interlocked,
a second position where the first lugs and the third lugs are interlocked, and the second lugs and the fourth lugs are not interlocked, and
a third position where none of the first lugs, the second lugs, the third lugs, and the fourth lugs are interlocked, so that the locking device is movable in an axial direction of each of the first riser section and the second riser section and is removable from the first connector assembly portion,
wherein,
the first lugs and the third lugs are configured and arranged to selectively and releasably interlock via a relative rotation between the first connector assembly portion and the locking device, and
the second lugs and the fourth lugs are configured and arranged to selectively and releasably interlock via a relative rotation between the second connector assembly portion and the locking device.

a locking ring comprising third locking members and fourth locking members, the locking ring being rotatably connected to the first connector assembly portion,
wherein,
the first locking members and the third locking members are configured and arranged to selectively and releasably interlock via a relative rotation between the first connector assembly portion and the locking ring,
the second locking members and the fourth locking members are configured and arranged to selectively and releasably interlock via a relative rotation between the second connector assembly portion and the locking ring,
the male connector of the first flange is fluidly connected to the upper main tubular element,
the female connector of the second flange is fluidly connected to the lower main tubular element, and
the locking ring is arranged between the male connector, the female connector, the at least one first auxiliary connector, and the at least one second auxiliary connector.
