Riser connector assembly

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 first locking members, the first connector assembly portion being attached to an end of the first riser section;
• a second connector assembly portion comprising second locking members, the second connector assembly portion being attached to an end of the second riser section;
• and
• a locking device comprising third locking members and fourth locking members, the locking device being rotatably connected to the first connector assembly portion, the locking device being configured to rotate between:
• a first position where each of the first locking members, the second locking members, the third locking members, and the fourth locking members are interlocked,
• a second position where the first locking members and the third locking members are interlocked, and the second locking members and the fourth locking members are not interlocked, and
• a third position where none of the first locking members, the second locking members, the third locking members, and the fourth locking members 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 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 device, and
• 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 device.
