Cold ironing for greener port stays

Abstract: Ships require continuous onboard electrical power to supply essential loads as well as hotelling demand. This extends to the period of time spent berthed, where the onboard power is typically provided by running of the vessel’s diesel generators. Cold ironing eliminates these in-harbour emissions by connecting the ship’s electrical network to the shoreside grid. This paper looks at various shoreside network topologies which can provide the required power when berthed from the local supply. Each topology presents different flexibility and efficiency attributes which can be best matched to the expected load by considering the harbour’s visiting ships’ electrical profile. Use is made of a multi-objective particle swarm optimisation algorithm to identify optimal configurations based on berth powers, with a view to reduce installation cost as well as shoreside emissions. These resultant emissions depend not only on the shoreside network but also on the local generation mix which therefore must be taken into account in order to provide a sensible comparison with onboard generation.
