Pounders Marine Diesel Engine and Gas Turbine
Major developments in two-stroke and four-stroke engine designs for pro-
pulsion and auxiliary power drives in the 5 years since the publication of the
eighth edition of Pounder’s Marine Diesel Engines call for another update.
This ninth edition reflects the generic and specific advances made by
marine engine designers and specialists in support technologies—notably tur-
bocharging, fuel treatment, emissions reduction and automation systems—
which are driven by: ship designer demands for more compactness and lower
weight; ship-owner demands for higher reliability, serviceability and over-
all operational economy; and shipbuilder demands for lower costs and easier
A historical perspective logs the nautical milestones over the first century
of marine diesel technology, which closed with the emergence of electronically
controlled low-speed designs paving the path for future so-called ‘Intelligent
Engines’. Development progress with these designs and operating experience
with the escalating number in service are reported in this new edition.
Since the last edition, increasing interest in dual-fuel (DF) and gas engines
for marine and offshore industry applications is reflected in an expanded chapter.
The specification of DF medium-speed diesel machinery for LNG carrier new-
building projects in 2002 marked the ousting of steam turbine propulsion from
its last bastion in commercial shipping. A growing number of these DF–electric
installations are now entering service, alongside direct-coupled low-speed
engine-powered LNG carriers equipped with boil-off gas reliquefaction plant.
Controls on exhaust gas emissions—particularly nitrogen oxides, sulphur
oxides and smoke—continue to tighten regionally and internationally, dictating
further responses from engine designers exploiting common rail fuel systems,
emulsified fuel, direct water injection and charge air humidification. These and
other solutions, including selective catalytic reduction and exhaust gas
