The freighter was a cargo ship that was employed by InGen Bioengineering to transport the captured male Tyrannosaur from Isla Sorna to JP: San Diego. The crew of the freighter was decimated en route to San Diego’s harbor which caused the ship to crash into the harbor master’s shack and dock.
The male Tyrannosaur hid in the cargo bay until it was released by security personnel. Dr. Ian Malcolm and Sarah Harding led the male back to the ship by transporting the baby T. rex to the ship. Once the male returned to the cargo hold, and Peter Ludlow killed by the baby, Sarah Harding tranquilized the buck. The rexes were returned to Sorna aboard the freighter.
