The objective of this paper is to study oil spills from damaged tanks during ship collision. The work comprises development of analytic models for estimation of oil spill and computational fluid dynamics (CFD) simulation with the Fluent software for verification of the simple models. In previous papers, oil leakage from a damaged tank with an opening in the bottom was investigated. The purpose of the present study is to extend the scope to cover oil spills for the case of collisions where the openings occur in the sides. In such cases, the gravitational force is very important as for the grounding scenario. However, for collision scenarios, there is a local imbalance due to different densities of the fluids even when the internal pressure is equal to the external pressure. A combination of water inflow and oil outflow through the opening may occur. Analytical calculations and time-domain simulations are applied to calculate the volume of oil outflow and the outflow rate versus time. Good agreement is obtained between the analytic model and the CFD analysis of the oil spill.
