Combustibles marinos residuales provenientes de la mezcla física de Bunker C (Fuel Oil), Gasóleo, y Diesel. Se utilizan en los motores o calderas. Existen varios grados clasificándose de acuerdo a su viscosidad y su escogencia o uso es especificado según el tipo de motor y sus requerimientos. Los grados conocidos internacionalmente son IFO 180, 240 y 380. En Costa Rica, RECOPE distribuye el IFO380 siendo sus clientes más comunes los barcos bananeros que llegan a cargar en el puerto de Moín, Limón.

b Notwithstanding the limits given, the purchaser shall define the maximum sulfur content in accordance with relevant statutory limitations. See Annex C c Due to reasons stated in Annex D, the implementation date for compliance with the limit shall be 1 July 2012. Until such time, the specified value is given for guidance. For distillate fuels the precision data are currently being developed. d Purchasers should ensure that this pour point is suitable for the equipment on board, especially if the ship operates in cold climates. e If the sample is not clear and bright, the total sediment by hot filtration and water tests shall be required, see 7.4 and 7.6. f If the sample is not clear and bright the test cannot be undertaken and hence the oxidation stability limit shall not apply. g If the sample is not clear and bright, the test cannot be undertaken and hence the lubricity limit shall not apply. h This requirement is applicable to fuels with a sulfur content below 500 mg/kg (0.050 mass %). i If the sample is dyed and not transparent, then the water limit and test method as given in 7.6 shall apply. |
