Cold ironing for greener port stays

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