A NOTE ON COSTS PER TON/MILE AT SEA

The adoption of costs per ton/mile at sea as a yardstick for cost minimization is fairly common in the marine transport literature. Working from empirically observed data it is possible to construct a family of curves (one for each ship size) showing the relationship between costs per ton/mile at sea and operating speed. (a) For a given speed, daily costs have an inverse relationship with ship size. (b) The optimal (i.e. cost minimizing) speed is higher the larger the ship size. The purpose of this note is to develop a simple mathematical model which will generate these curves and thus to give some theoretical underpinnings to the work of Gilman and others.
