Abstract
A pump module for a drilling riser includes at least one pump mounted to a frame, the frame including features to couple the frame to a segment of riser. A fluid inlet is affixed to the frame. The fluid inlet is in fluid communication with an intake of the at least one pump. The fluid inlet has features to make fluid tight hydraulic connection to a fluid outlet of the riser segment when the frame is coupled thereto.

A pump module for a drilling riser comprising:
- at least one pump mounted to a frame to form the pump module, the pump module including features to couple the pump module to a riser segment;
- and
- a fluid inlet affixed to the pump module, the fluid inlet in fluid communication with an intake of the at least one pump, the fluid inlet having features to make a fluid tight hydraulic connection to a fluid outlet of the riser segment when the frame is coupled thereto;
- wherein the riser segment includes the fluid outlet and a docking arrangement, wherein assembly of the pump module to the docking arrangement comprises insertion of retention pins in mating openings in the docking arrangement and insertion of the fluid inlet in an opening in the docking arrangement coupled to the fluid outlet.
