Most containerships are designed to travel at speeds around 24 knots. It also reflects the hydrodynamic limits of the hull to perform within acceptable fuel consumption levels. Represents the optimal cruising speed a containership and its engine have been designed to travel at. While shipping lines would prefer consuming the least amount of fuel by adopting lower speeds, this advantage must be mitigated with longer shipping times as well as assigning more ships on a pendulum service to maintain the same port call frequency. At 21 knots, this consumption drops to about 150 tons per day, a 33% decline. For instance, while a containership of around 8,000 TEU would consume about 225 tons of bunker fuel per day at 24 knots. Proceedings of the 2009 International Association of Maritime Economists (IAME) Conference, June, Copenhagen, Denmark.įuel consumption by a containership is mostly a function of ship size and cruising speed, which follows an exponential function above 14 knots.
