How to Improve Efficiency
The efficiency of ships has become a hot topic in the maritime industry in recent years. Increasing fuel prices and the peak oil prices reached in the middle of 2008 were one trigger for the efficiency and the clean technology market receiving a lot of attention.
Interest in saving fuel remains a high priority – and all cost savings are of course very welcome in times of low market demand.
But it is not only financial savings that are driving the push for more efficient ships. Environmental considerations and the need to cut back emissions also feed the desire to boost efficiency in maritime transportation. Almost all emissions from ships are reduced when less energy is consumed.
The Second IMO GHG Study, in 2009, identified a significant potential for further improvements in energy efficiency, mainly through the use of already existing technologies such as more efficient engines and propulsion systems, improved hull designs and larger ships: or, in other words, through technical- and design-based measures that can achieve noteworthy reductions in fuel consumption and resulting CO2 emissions on a capacity basis (tonne-mile). The study also concluded that additional reductions could be obtained through operational measures such as lower speed, voyage optimization, etc.
The EEDI addresses the former type of measure by requiring a minimum energy efficiency level for new ships; by stimulating continued technical development of all the components influencing the fuel efficiency of a ship; and by separating the technical and design-based measures from the operational and commercial ones.
There is, therefore, every confidence, among the vast majority of the international maritime community, that the EEDI will result in more energy efficient ships, in reduced emissions of GHGs, in environmental effectiveness and in a significant contribution by a global industry to the global efforts to stem climate change.
The Shipping Efficiency Guide to Clean Technologies gives an easy to digest scope of the emission reduction technologies available and their associated fuel saving potential, expressed as a percentage for ease of usability.
