Abstract
To convey the energy coming from offshore wind-farms to the end-users, a network of offshore transmission platforms with sub-sea cables is in place, functioning as the supply chain for electricity. This research addresses the development of an optimization model, OptiFleet, which targets the problem of vessel fleet management to perform the transportation of crew and cargo to and from the platforms. OptiFleet provides strategic decision support to the Transmission System Operator on the optimal accommodation and transportation strategy. In particular the model aims to generate an optimum fleet size and mix, this is the number and the type of vessels in the fleet to support the platform maintenance campaigns.
