@article{Laulajainen_2011, title={Oil product tanker geography with emphasis on the Handysize segment}, volume={189}, url={https://fennia.journal.fi/article/view/2839}, abstractNote={Novel movement data are used to chart worldwide mineral oil product shipments by Handysize (15,000–59,999 dwt) and larger (60,000+ dwt) tankers. The data are from 2004 which allows comparisons with earlier studies about crude oil shipments. Theory about ship movements and attached freight rates (RP Rule) gets indirect support. Non-existence of global data below the Handysize enforces the use of fragmentary data from a refinery company and a world-class port. Both data sets are believed to be representative for the purposes used. Export<br />shipments of the refinery company reveal a linear non-logarithmic distance function for vessel classes in the 2,000–67,000 dwt range. The function is practically<br />identical with oil product exports from the said port. The thinking is then extended to larger vessel sizes and crude oil cargoes, the principle of fungibility.}, number={1}, journal={Fennia - International Journal of Geography}, author={Laulajainen, Risto}, year={2011}, month={Sep.}, pages={1–19} }
