THESIS FOR DEGREE OF DOCTOR OF PHILOSOPHY Air Pollution from Ships in Danish Harbours: Feasibility Study of Cold-ironing Technology in Copenhagen FABIO BALLINI Department of Naval, Electrical, Electronic and Telecommunication Engineering UNIVERSITY OF GENOA, Italy 2013 BALLINI FABIO Department of Naval, Electrical, Electronic and Telecommunication Engineering (DITEN), University of Genoa, Italy ABSTRACT Annex VI of the MARPOL Convention (IMO) and a number of EU directives, principally Council Directive 1999/32/EC, set the regulatory framework for the shipping industry and signature member states, while at the same time limiting unilateral regulatory measures. This thesis has studied best-practice examples of unilateral emission control in the North Sea and Baltic Sea region. The main study case has been the Port of Copenhagen. To accommodate the growing cruise traffic, a new cruise pier has been constructed that is prepared for cold-ironing, a technology that allows vessels at berth to use shore power rather than electricity generated by auxiliary engine. To assess the socio-economic impact of this technology, I applied an advanced external air pollution evaluation model, studying emissions from international shipping in the North Sea and Baltic Sea within the specific timeframe of May-August 2012. My calculations demonstrated that the total external health cost of emissions from cruise ships at berth in Copenhagen within the 5-month timeframe was €5,384,086. My calculations also showed that a scenario of 60% of visiting cruise ships using shore power (i.e. approx. the total capacity of the proposed cold ironing utility) would result in an i external health cost saving of NOx SO2 and PM emissions respectively of €2,675,384, €28,535 and €175,590. My cost-benefit analysis demonstrated that the external health costs would balance the capital cost in harbour-side cold-ironing infrastructure in 10-15 years. The thesis also identified two prerequisites for the economic feasibility of shore power in Copenhagen. Firstly, Denmark needs to obtain an exemption from Community Directive (2003/96/EC), Article 14(1)(c) to exempt vessels from paying local Danish environmental tax on shore power. Secondly, a pool of major Baltic destinations needs to be created to ensure that cold-ironing becomes a benchmark incentive-based technology in the region with which to reduce emissions in harbour environments.
