What is CODEG? CODEG stands for “Combined Diesel and Gas Turbine Electric Drive System”.
A CODEG propulsion system consists depending on the size of the ship of
1 or 2 gas turbines generator sets and 2 to 4 diesel engine generator sets.
Every set is providing electric power for the electric propulsion motors and
also for the on-board electric power demand. The steam needed for the hotel
accommodation will be produced by exhaust gas heat boilers, located in the
exhaust gas ducts of the gas turbines.
What is CODEG?
Series 8000 as generator set available
> Fulfils all emission laws,
(CLEAN class notation acc. to DNV rules, without
secondary methods)
> Competitive fuel consumption
> Robust and compact design
> New proven technologies have been applied
> Electronically controlled and monitored
> Long maintenance overhaul intervals, i.e. low
maintenance costs
One source for all of your needs
MTU can offer the complete CODEG propulsion system:
> Gas turbine generator sets, based on the well proven
GE gas turbines, type LM2500 and LM2500+
> Diesel engine generator sets, based on the new and
low emission MTU diesel engine, type 20V 8000 M50
> Customized ship-side accessories, such as hydraulic
starting systems, fuel service systems, silencers, etc.
> Professional integration, installation and service
support
Green ship, i.e. low exhaust emissions
Several countries, e.g. Alaska, Scandinavia, California have
released strong emission regulations for ships approaching
their shore and harbours, mainly regarding NOx and SOx
emissions.
It is therefore important for modern cruise ships to fulfil
these regulations.
> The MTU diesel engine 20V 8000 M50 has been
designed to fulfil the most stringent emission require-
ments.
> The gas turbines, LM2500 and LM2500+ also fulfil the
most stringent emission requirements.
Low noise emissions
For a cruise ship the noise emissions are of high impor-
tance.
> The 20V 8000 M50 is elastically mounted on the steel
base frame, which is itself elastically mounted to the
ship’s foundation. This double elastic mounting arrange-
ment reduces the structureborne noise effectively. For a
reduction of exhaust gas noise MTU is able to provide a
suitable silencer.
> The gas turbines are rotating machines and have there-
fore naturally low structure borne noise levels, but are
also mounted elastically to the ship’s foundation, which
reduces the noise emissions even more. The air borne
noise levels are effectively reduced by silencers for the
inlet air and exhaust gas.
Additional cabins
> Due to the location flexibility of the diesel and gas
turbine generator sets, the machinery spaces can be
placed anywhere in the ship. The gas turbine generator
sets can be placed even on the upper deck, due to their
relative low weight and this deletes also the air inlet
and exhaust gas ducts.
> The MTU gas turbine and diesel engine generators sets
are of a very compact design, which leads to less
required machinery space.
Low personnel costs
> The MTU gas turbine and diesel engine generator sets
are designed for easy operation and maintenance.
High efficiency
> In the power range of 90% to maximum rating the GE
gas turbines, type LM2500 and LM2500+ show excel-
lent efficiency. As the cruise ship has varying demands
of electric power, a combination with the latest MTU
diesel engine generator set cover lower load demands.
The prime mover 20V 8000 M50 shows a competitive
fuel consumption, also in part load.
The gas turbine exhaust gases could also be used for
steam production for the hotel accommodation, using
heat recovery boilers.
Why is CODEG the better solutionfor cruise ships?
Compared to other propulsion systems for cruise ships, like conventional Diesel
Mechanical propulsion systems, conventional Diesel Electric propulsion systems
or even the advanced Combined Gas Turbine and Steam Turbine propulsion system,
CODEG has the following advantages:
