Abstract
Cold-ironing is the practice that enables to power commercial ships by a link to
fixed electricity network, in order to reduce pollutant emissions in the port areas caused by
marine fuels in auxiliaries engines feeding on board installations during ships stops at quays. The
present paper aims to provide an overview of the most important technical and functional features
of the concerned ships power systems and to analyze the technical, economic and
financial feasibility of this system. In the first part the main technical-constructive elements
for the application of Cold-ironing to different types of ship (such as voltage,
frequency, power supply and power demand on the quay) are analyzed. The variety of
functional situations does not allow to establish general constructive solutions since
the cold-ironing system is depending both on the operational mode and the layout of
each terminal. In the second part of the paper it has been analyzed the case study of the cruise
terminal in Venice (VTP Spa Venice Passenger Terminal) with the aim of verifying the
feasibility of a cold- ironing system for power supply of cruise ships on quays. The analysis
was based on ships timetable for the year 2012, which includes the arrivals and the
departures of 86 different ships with a global volume of 570 movements. Starting from data on
dwell times, following the guidelines of the MEET methodology for estimating emission
factors [3] it has been estimated pollutant emissions (nitrogen oxide NOx, sulfur oxides
SOx, volatile organic compounds VOC, particulates PM, carbon monoxide CO) as a basis to
calculate externalities to be considered for the Cost-Benefit Analysis (CBA). Based on a
probabilistic analysis of the terminal occupation by ships (disposal of ship stalls on each quays)
five operational scenarios were defined. Each scenario has been defined on the basis of
an economic evaluation by means of a cost-benefit parametric analysis with the aim of providing
the maximum financial results for assigned budgets. From a comparison of the results of the
cost-benefit analysis and an estimate of possible investment costs obtained from USA case studies,
it is noticed that the scenario providing coverage of both financial and economic
investment includes the minimum number of electrified stalls and a ships journeys
reorganization. It was also proposed a sensitivity analysis of CBA for the evaluation of
indicators variations according to
reference conditions variation.
