Growing ecological concern and awareness is now also targeting marine fuels with increasing levels of attention. Onshore use of fuels is already legislated by the EEC Large Combustion Plant Directive and national directives. There are initiatives under way (French Memorandum) to tighten further legislated emission standards. With the exception of Scandinavia and California there are so far no restrictions on marine fuels. In this situation IMO has the lead in formulating emission reduction targets. The objective is to reduce SOx by 50% by the year 2000 and NOx by 70%, also by the year 200. Although there is no binding legislation as yet on marine fuels there seems to be a school of thought that marine gas oil sulphur will be reduced to an oil wt % in line with heating oil. Marine diesel fuel sulphur will be reduced to a 6.5 wt % S, while in cased with differentiating qualities between coastal use (1.0 wt % S) and open sea use, the range will be from 2.0-3.5 wt % S. As in the field of legislative, regulatory or voluntary marine fuel quality restrictions there is uncertainty as to strategies the petroleum industry and their key heavy fuel oil clients in the power generation industry will adopt. There is certainty, on the other hand, that lower sulphur products will carry a substantial premium as the authors' company have shown: US$8-15/t for vacuum gas oils and US$34- 37/t for atmospheric residues. It is against these premia that the marine industry will have to evaluate 'marine engineering' related alternatives. But there is good news; the refinery restructuring process necessary to cope with all the environmentally driven changes is not likely to generate blending components with quality characteristics detrimental to marine applications.
