Two models of supertanker lightering operations are developed. The first is a set of linked queueing models while the second employs a five-dimensional state space to model the process using the theory of Markov processes. Both models estimate delays to supertankers and to lightering vessels as functions of the supertanker arrival rate, the number of lightering vessels deployed, the loading and unloading times of lightering vessels, the travel times to and from the port and the number of berths in the port used for lightering. The models are compared conceptually and empirically. The model input assumptions are tested against a small data set and the output predictions are also compared with observed data. The use of the models as planning tools is also illustrated.
