Abstract: This article presents a model based on OEE, called OLUE, to measure the efficiency of loading and unloading operations in liquid bulk storage terminals. Through a focus group, a model was developed with six specialists who validated this model in the management of operations in Brazilian liquid bulk storage terminals. The model was implemented in a liquid bulk storage terminal to validate its practical applicability and presented satisfactory results in its practical application. The results were about which activities and events carried out in loaded trucks undermine efficiency. Thus, it provides the management of these terminals with the possibility of management through data and facts. The measurement of loading and unloading resources in liquid bulk storage terminals has not yet been disclosed, so this proposed model can improve the management of these resources and the operations of these environments.

Keywords: efficiency; loading and unloading bulk liquid; operating terminals; overall equipment effectiveness; OEE; efficiency measurement; overall load and unload stations effectiveness; OLUE.
