Abstract
This study explores tramp shipping operations, where efficient fuel management is important for financial success, environmental responsibility, and global sustainability goals. The paper focuses on integrating speed-dependent non-linear fuel consumption curves into the basic tramp ship routing and scheduling problem, recognizing the need for precise fuel consumption estimation. A non-linear mixed integer programming model is proposed for routing, scheduling, and speed optimization. The model is to study the impact of variable elasticities across different speed intervals, aligning closer to the complexities of a per vessel-specific fuel consumption. Finally, we will examine the impact of introducing speed and specially speed-dependent fuel-speed elasticities and calculate the time charter equivalent as an economic measure, based on the outputs of the model with constant elasticity and the model with speed-dependent elasticity.
