Oil spill in oceans is identified as a key environmental issue resulting in water contamination and major harm to marine life. These spills in ice-infested waters can be even more catastrophic as the process of ice melting is non-trivial and adds an additional complexity in determining the extent of the oil spread from the initial spill zone. The prediction of the impact and extent of the spill assists in employing the required clean-up countermeasures. A validated numerical model that simulates the oil spread is reported in this study, where the spread of an oil layer in ice is analyzed. Experiments in literature have shown that for solar radiation flux higher than 0.5 kW/m2, the oil temperatures can be around 5 - 6 ºC even if the ambient is at sub-zero temperature. This surface heating is simulated in the numerical model to study the effect of in-depth heating of oil on the ice melting to further analyze the spreading of oil in the melt zone.
