In 2294, the transport was carrying passengers to the Norpin colony when the ship experienced an overload to one of its plasma transfer conduits. When the captain brought the ship out of warp, it hit the gravimetric interference caused by the gravitational field of a previously uncharted Dyson sphere. To help the Enterprise escape La Forge and Scott brought the Jenolan to a stop within the sphere's hatch, using the ship's shields to prevent the hatch from closing. However, the strain disabled the Jenolan once more, preventing it from moving out of the way so the larger ship could pass.
