Waterborne data center facility systems and methods comprising a purpose-built marine vessel, a pre-fabricated data center facility structure, a plurality of computer systems, a plurality of energy-efficient water-based heat exchange systems, a plurality of energy efficient closed loop cooling systems, a plurality of data center modules and a plurality of electrical power generators. Described systems and methods may be employed to quickly deploy an energy-efficient waterborne data center facility. Described waterborne data center facility is transportable and may be moved to areas where data center facility and data center type services are needed. Water-based heat exchange and closed-loop cooling system enable energy-efficient cooling to data center facility and the plurality of computing systems therein. Power generators may be used to provide power to data center facility. Waterborne data center facility may prove helpful in areas following natural disasters or for military purposes where data center services are needed but not readily available.
