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-

duction system for generating drinking

water, both for meeting on-board needs

and for supplying drinking water to the

local community.

Transporting the barge Seaborne transport is via lift ship

or towable, submersible transport

barge. River-bound transport is

by tugs.
