Abstract: Marine fuel compositions that are low sulfur and have improved wax flow viscosity are disclosed. An example marine fuel composition may have the following enumerated properties: a sulfur content of about 0.50% or less by weight of the marine fuel composition; a density at 15° C. of about 0.86 g/cm3 to about 1.01 g/cm3; a kinematic viscosity at 50° C. of about 1 centistoke to about 700 centistokes; and a ratio of kinematic viscosity to wax flow viscosity of greater than 1, wherein the wax flow viscosity is determined using a minimum operating viscosity of about 8 centistokes at 50° C.

Abstract: Heavy hydrotreated gas oil compositions are provided, along with marine fuel oil compositions and marine gas oil compositions that include a substantial portion of a hydrotreated heavy atmospheric gas oil. The hydrotreated heavy atmospheric gas oil can correspond to a gas oil with a relatively low viscosity and an elevated paraffin content in a narrow boiling range which results in a relatively high cloud point and/or pour point.

Abstract: Compositions corresponding to marine diesel fuels, fuel oils, jet fuels, and/or blending components thereof are provided that include at least a portion of a natural gas condensate fraction. Natural gas condensate fractions derived from a natural gas condensate with sufficiently low API gravity can provide a source of low sulfur, low pour point blend stock for formation of marine diesel and/or fuel oil fractions. Natural gas condensate fractions can provide these advantages and/or other advantages without requiring prior hydroprocessing and/or cracking.

Abstract: Methods for making marine fuel oil compositions and/or marine gas oil compositions are provided. The fuel oil compositions can include a distillate fraction having a sulfur content of 0.40 wt % or more and a resid fraction having a sulfur content of 0.35 wt % or less. The distillate fraction can also have a suitable content of aromatics and/or suitable combined content of aromatics and naphthenes. The distillate fraction, optionally blended with a low sulfur distillate fraction, can be used as a gas oil fuel or fuel blending component. Using a distillate fraction with an elevated sulfur content and aromatics content as a blend component for forming a fuel oil can result in a marine fuel oil with improved compatibility for blending with other conventional marine fuel oil fractions.

Abstract: Provided are marine fuel compositions having acceptable wax behavior. In one form, the marine fuel composition has the following enumerated properties: a kinematic viscosity at 50° C. of about 5 cSt to about 700 cSt; a wax endpoint temperature of less than about 100° C.; and a ratio of kinematic viscosity at 100° C. to operating viscosity greater than 1, wherein the operating viscosity is at least about 2 cSt. The marine fuel composition exists in a liquid phase with essentially all the wax in the composition melted (essentially free of solid wax) prior to fuel injection into a marine engine.
