  • Combination carrier: A ship designed to carry either oil or solid cargoes in bulk
  • Nearest land: The term "from the nearest land" means from the baseline from which the territorial sea of the territory is established
  • Special area: A sea area where for recognized technical reasons in relation to its oceanographical and ecological condition and to the particular character of its traffic the adoption of special mandatory methods for the prevention of sea pollution by oil is required
  • Special Areas List (for this annex):

  1. the Mediterranean Sea
  2. the Baltic Sea area

·  Instantaneous rate: Rate of discharge of oil content means the rate of discharge of oil in L/hr at any instant divided by the speed of the ship in knots at the same instant
·  Slop tank: A tank specifically designated for the collection of tank draining, tank washing and other oily mixtures
·  Clean ballast: The ballast in a tank which, since oil was last carried therein, has been so cleaned that effluent therefrom if it were discharged from a ship would not produce visible traces of oil on the surface of the water
·  Segregated ballast means the ballast water introduced into a tank which is completely separated from the cargo oil and oil fuel system

·  Oil residue (sludge) tank: Tank which holds oil residue (sludge) from which sludge may be disposed directly through the standard discharge connection
·  Oily bilge water: Water which may be contaminated by oil resulting from things such as leakage or maintenance work in machinery spaces. Any liquid entering the bilge system including bilge wells, bilge piping, tank top or bilge holding tanks is considered oily bilge water
