MAN Diesel & Turbo
The responsible way in leading technology
MAN Diesel & Turbo is the world’s leading designer and manufacturer of low and
medium speed engines. Our involvement with electrical power generators goes
back to 1904 when we supplied the first ever diesel generator sets to the Kiev
Tram System.
Since those early days, MAN Diesel & Turbo has never lost its technological preeminence
in the large engine field. Likewise, our engines have never relinquished
their status as the most efficient combustion engines available.
More than ever before, MAN Diesel & Turbo’s development focus is on the envi-
ronmental performance of our engines. Using our unrivalled grasp of large engine
technology, we aim to make our engines progressively cleaner, more powerful and
more efficient.
With our absolute commitment to reducing emissions while increasing fuel effi-
ciency and power density and, with our active partnership in the emissions law
making process, we intend to be part of the global emissions solution.

Floating Diesel Power Stations
For coastal regions or large river sites, “floating power stations” are an ideal solution
for meeting power supply needs on a fast track basis.
The advantages are:
Simple and straight forward location of power
station where power is required.
Supports rapid infrastructure development in remote
regions.
Short building times: for example 70 MW power
station can be installed in less than 12 months.
Reduced reliance on poor or nonexistent local
capabilities.
Floating power stations can take advantage of finan-
cing incentives from shipbuilding regions.
Unaffected by landslides and earthquakes.
Minimal environmental impact as only a small area
of coastal or up-river land is required.
Independence from local infrastructure.
The floating Diesel power station can be supplied
with two cooling alternatives: sea water cooling or
roof-mounted radiator equipment.
Minimum operator‘s investment risk due to the mobi-
lity, versatility and adaptability of this type of plant.

Basic design and structure
Main deck Upper deck Lower deck Pontoon: Air cooled option
Main deck
Diesel generating sets with cooling water, fuel, luboil
separator, nozzle cooling modules, etc. Workshops
(mechanical and electrical) and electrical switchgear.
The fully equipped, noise-protected workshops and
tool rooms mean that maintenance and repair work
can be carried out on board.

room is noise-protected, air-conditioned and fire-protected.
The social and sanitary rooms are designed to
accommodate a crew of 15.
Lower deck
Tanks with transfer pumps, fuel processing and seawater
pumps. The seawater pump room features a
multi-stage filter system for seawater cooling. The tank
capacities are designed for approx. two days of operation
at 100% load. The fuel processing equipment is
housed in separately ventilated and fire proof compartments.
Sea water cooled option
Pontoon

Transporting and Tank Farm
Transportation of a 124 MW floating diesel power station
Transporting the barge
Seaborne transport is via lift ship or towable, submersible
transport barge. River-bound transport is by tugs.
Waste-heat utilisation
The overall efficiency of the power plant can be improved
by utilising waste engine heat from the exhaust
gas and cooling water, e.g. in a freshwater production
system for generating drinking water, both for meeting
on-board needs and for supplying drinking water to
the local community.
Tank farm
Tank farm
Usually the tank farm for fuel storage is erected on
land, although it can be installed on an additional
“tanker barge”. The use of “tanker barges” ensures
complete independence from the local infrastructure.
Fuel is supplied by tanker, tank trailer lorry, barge or
pipeline.
