The net advantage regarding C02 is under discussion, but ideally up to some 25 per cent reduction may be realized. The current downturn has been characterized as one of the longest ever. Shipyards, largely in the Far East, are running out of business. Some evidence shows that there are cases of ships being recycled at an age as early as seven years. Thorough analysis, taking into account regional factors, shows that a strong case for gas-fuelled ships does exist. Figure 7 shows how clusters of year build, distribution of demand over areas, fleet composition with concentration of energy demand and seasonality need to be assessed in order to evaluate whether there is a justification to use LNG as fuel for shipping.
