MAN Diesel – Floating Diesel Power Stations
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 non-
existent local capabilities.
>> Floating power stations can take
advantage of financing 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 infra-
structure.
>> 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 mobility, versatility
and adaptability of this type of plant.

The control room is noise-protected,
air-conditioned and fire-protected. The
social and sanitary rooms are designed
to accommodate a crew of 15.
The fully equipped, noise-protected
workshops and tool rooms mean that
maintenance and repair work can be
carried out on board.

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.
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 pro-

Transporting the barge Seaborne transport is via lift ship
or towable, submersible transport
barge. River-bound transport is
by tugs.
