Claim 10:
11. A system, comprising:
a drill string configured to support a tool to drill a wellbore;
a casing configured to be inserted into the wellbore to support the wellbore;
a casing assembly device configured to assemble the casing about the drill string on-site at a subsea location; and
an annular sleeve comprising one or more axially-extending passageways extending from a first end and a second end of the annular sleeve, wherein the second end of the annular sleeve is configured to be positioned within an annular space between the drill string and the casing, the first end of the annular sleeve is configured to be positioned axially above the casing, and the annular sleeve is configured to divert a flow of fluid from the wellbore into the one or more axially-extending passageways of the annular sleeve and to transfer the flow of fluid to a fluid processing system as the casing is assembled and inserted into the wellbore, and wherein at least one of the drill string or the casing is configured to move in an axial direction relative to the annular sleeve while the flow of fluid is diverted into the one or more axially-extending passageways.
