This paper discusses a real ship routing problem with inventory control in supply points (offshore platforms) and demand requirements in consumers points (coastal terminals) which appear in pickup and delivery operations of different types of crude oil. The transportation of the products is largely the result of the need to maintain the inventory in each platform between minimum and maximum levels. The routing and scheduling of the fleet aims to obtain minimum variable cost solutions, and should consider several operational constraints, such as the feasibility of docking the vessels at the ports and simultaneous dockings in terminals with more than one berth. In this work, real data examples from a case study in a national oil company, were solved by means of an implementation of a mixed integer linear model that describes the problem and by a local search heuristic.
