Farrell
Lieutenant Farrell was a Starfleet officer and junior engineer aboard the . 

In 2370, Farrell worked on the deuterium cartridges with Ensign , shortly before the activation of a new warp core. ()

In 2371, Farrell analyzed the data from a tricorder found on a dead Romulan aboard the Amargosa observatory. After Lieutenant Commander Geordi La Forge was released from captivity by the Duras sisters, Farrell asked if they could run some diagnostics on the port plasma relays, but the diagnostics were never initiated because the Enterprise was attacked by the Duras, who were monitoring the Enterprise shield frequency through a visual acuity transmitter in La Forge's VISOR. Farrell tried to make repairs to the damaged warp core, but was forced to evacuate main engineering after a coolant leak led to a warp core breach. While leaving the stardrive section, La Forge and Farrell found a group of children who had been separated from their parents and brought them to safety in the saucer section, protecting them during the rough landing on the surface of Veridian III.
