Abstract
A device automatically makes up a riser string from riser spools, each having an ancillary line and dog-type connectors. A support member supports a second riser spool for connection. A torque arm above the support member hinges open to accept a first riser spool and hinges close to engage the first spool and rotate the first spool to align its ancillary line with the ancillary line of the second spool. A guide arm above the support member hinges open to accept the first spool and hinges closed to engage and radially position the first spool while allowing vertical movement of the first spool. Connector actuators are positioned around the support member to actuate the connectors when the first spool is lowered onto the second spool.
