Static annular sealing systems and integrated managed pressure drilling riser joints for harsh environments

A harsh environment integrated MPD riser joint comprising:

• a dynamic annular sealing system comprising:
• an upper sealing element, and
• a lower sealing element;
• a static annular sealing system disposed below the dynamic annular sealing system comprising:
• an upper annular packer system and an upper connection sealing element disposed within the upper annular packer system, and
• a lower annular packer system and a lower connection sealing element disposed within the lower annular packer system;
• a flow spool disposed below the static annular sealing system that diverts returning fluids to the surface,
• wherein the dynamic annular sealing system maintains annular pressure during drilling operations while the static annular sealing system is disengaged,
• wherein the static annular sealing system maintains annular pressure during connection operations while the dynamic annular sealing system is disengaged, and
• wherein a top mandrel is attached to a top distal end of the upper connection sealing element and a bottom mandrel is attached to a bottom distal end of the upper connection sealing element and the top mandrel and bottom mandrel secure the upper connection sealing element in place relative to the upper annular packer system with a plurality of locking dogs.
