# §155.200. Definitions.


As used in this subpart:

Inland oil barge means a tank barge carrying oil in bulk as cargo certificated by the Coast Guard under [46 CFR chapter I](/cfr/46/chI.md), subchapter D for river or canal service or lakes, bays, and sounds service.

On-deck spill means a discharge of oil on the deck of a vessel during loading, unloading, transfer, or other shipboard operations. An on-deck spill could result from a leaking fitting, an overfill, a bad connection, or similar operational mishap. The term on-deck spill is used to differentiate these operational discharges from those caused by collision or grounding where the hull is punctured and a tank is ruptured, resulting in an uncontrolled discharge of oil into the marine environment.

Offshore oil barge means a tank barge carrying oil in bulk as cargo, including dual-mode integrated tug-barges, certificated by the Coast Guard under [46 CFR chapter I](/cfr/46/chI.md), subchapter D, for navigation in waters outside the Boundary Lines, as defined in [46 CFR part 7](/cfr/46/part7.md), in any ocean or the Gulf of America; any tank barge in Great Lakes service; or any foreign flag tank barge.

Oil tanker means a self-propelled vessel carrying oil in bulk as cargo, including integrated tug-barges designed for push-mode operation.

Vessel carrying oil as secondary cargo means a vessel carrying oil pursuant to a permit issued under 46 CFR [30.01-5](/cfr/46/30.01-5.md), [46](/cfr/46/46.md) CFR 70.05-30, or [46 CFR 90.05-35](/cfr/46/90.05-35.md) or pursuant to an International Oil Pollution Prevention (IOPP) or Noxious Liquid Substance (NLS) certificate required by [§ 151.33](/cfr/33/151.33.md) or [§ 151.35](/cfr/33/151.35.md) of this chapter; or any uninspected vessel that carries oil in bulk as cargo.
