Subsea pumping and booster system

A system, comprising:

• a pumping unit, the pumping unit comprising:
• a plurality of tubulars, the plurality of tubulars directing flow from a first end to a second end;
• two or more electric submersible pumps (ESPs) positioned within at least two or more tubulars of the plurality of tubulars, the two or more ESPs receiving production fluid and increasing a pressure of the production fluid;
• a frame associated with at least the two or more tubulars of the plurality of tubulars, wherein at least the two or more tubulars of the plurality of tubulars are at least partially within a perimeter of the frame;
• and
• a plurality of valves associated with the plurality of tubulars, the plurality of valves each independently moveable between respective open positions and closed positions, wherein respective positions of groups of valves correspond to operational configurations selected to adjust operation of the two or more ESPs;
• and
• a base unit, comprising:
• a receptacle adapted to receive the frame of the pumping unit;
• one or more outwardly extending posts, forming at least a portion of the receptacle, extending outwardly away from the frame, when the frame is positioned within the receptacle, along an axis of the base unit that is aligned with at least one axis of the plurality of tubulars;
• a subsea connector for receiving a production line and directing production fluid toward the pumping unit;
• and
• an isolation valve, upstream of the subsea connector, to block the production fluid.

A system, comprising:

• a pumping unit, the pumping unit comprising:
• a plurality of tubulars, the plurality of tubulars directing flow from a first end to a second end;
• two or more electric submersible pumps (ESPs) positioned within at least one tubular of the plurality of tubulars, the two or more ESPs receiving fluid and increasing a pressure of the fluid;
• a support structure for the plurality of tubulars;
• and
• a plurality of valves associated with the plurality of tubulars, the plurality of valves each independently moveable between respective open positions and closed positions, wherein a plurality of valve configurations correspond to a plurality of operational modes for the two or more ESPs;
• and
• a base unit, comprising:
• a receptacle adapted to receive the pumping unit;
• sets of posts arranged at ends of the receptacle, wherein each post of each set of posts includes a sloped upper post portion, the sloped upper post portion being outwardly sloped, away from the receptacle, along an axis of the base unit that is aligned with at least one axis of the plurality of tubulars;
• a connector for receiving a fluid line;
• and
• an isolation valve, upstream of the connector.
