With the introduction of containerization, liner shipping services have been popular due to their highly predictable schedule. Once the vessels deviate from fixed schedule and routes, it will cause liner shipping companies to bear extra operational expenses, and moreover, result in decline in reputation. Therefore, it’s essential for companies to design the sailing speed of the liner vessels in advance in order to adhere to service requirements as well as increase operating profitability. A non-linear programming model is proposed to determine the optimal speed of general liner services with the objective of minimizing partial operational costs. The main determining components are bunker consumption costs, vessel charter fees and delay expenses, constrained by exhaust gas emission allowance, vessel engine ability and chokepoint delays. This model serves as a reference for liner shipping companies to design new vessel deployment and operating plan or modify current liner service design.
