Marine distillate fuels specifi cations –
today and tomorrow
Ø. Buhaug, Statoil ASA, Norway
When MARPOL Annex VI entered into force in 2005, it marked not
only the end of a long struggle by IMO to regulate harmful emissions
from international shipping, its entry into force also immediately
triggered a review of the regulation with a view to tighten emissions
standards established in the original Annex VI. As known to many
readers, strict future IMO regulations on NOx and SOx emissions are
agreed. The new regulations which will be implemented in steps from
1. July 2010 towards 2020 will have far reaching implications for
marine fuels and diesel engines. In particular, a global limit of 0.5%
sulphur is part if the new IMO regulation. Production of residual fuels
with 0.5% sulphur is believed to be economically unattractive. This
has lead to the description of the global cap of 0.5% S as ‘end of heavy
fuels’ or ‘global distillates’. These future distillates are likely to be very
different from present distillates, however, and the characteristics of
these fuels remain unclear. This paper presents data on present day
marine distillates and discusses issue relevant to the use of distillate
fuels including:
• Fuel lubricity
• Fuel particle contamination
• Fuel water and microbial contamination
• Distillate safety issues

The objective of this study is to discuss and demonstrate the emission
reduction potential of high cetane number paraffi nic diesel fuels in
engine peration. The idea behind the study is to utilize the physical
and chemical renewable fuel properties, that are different from those
of the traditional crude oil based fuels. The ultimate goal is then to
develop optimum combustion technologies for these new fuels and
make a remarkable emission reduction in engine combustion. These
new fuels do not suffer from storage and low temperature problems,
as the Fatty Acid Methyl Ester (FAME) fuels, often called “biodiesel”,
often do. The very high cetane number, the absence of Polyaromatic
Hydrocarbons (PAH) and the absence of Sulphur allow far more
advanced combustion strategies than have been possible with current
fossil fuels. Due to these advantageous properties, these new
combustion technologies allow us to reduce signifi cantly Nitrogen
Oxide (NOx) emission without suffering from traditional trade-off
