Mobile offshore carbon capture and sequestration systems and methods using jack-up structure

Abstract

System 200 comprises first offshore installation 60 comprising a jack-up structure comprising floatable hull 62 and three or more legs 64, configured to be raised and lowered vertically and engaged with or landed on seafloor 90. The jack-up structure has a carbon dioxide, CO2, removal system comprising CO2 removal unit(s) 3 (including fans and CO2 adsorption and / or absorption units), CO2 dehydration unit(s) 5, and CO2 compressor(s) 7. The CO2 removal unit is configured to remove CO2 from atmospheric air through Direct Air Capture (DAC) and form captured CO2. The system also comprises transfer conduit(s) 92 fluidly connecting the CO2 compressor(s) with a second offshore installation 70. The CO2 compressor is configured to transfer the captured CO2 through the conduits to the second installation. Second offshore installation 70 comprises CO2 injection well 94 configured to route the captured CO2 into a subsurface storage formation 110.
