Flagship, a part EU-funded maritime transport project, has
achieved major advances in accurately measuring on-board
power requirements and thereby enabling a reduction in fuel
consumption through the development of Flagship-EEM
(Energy Efficiency Monitoring).
The system enables data acquisition and analysis to
continuously evaluate power requirements at every stage of a
vessel's voyage. The system provides information that enables
improved fuel consumption that can reduce both operational
costs and its environmental impact.
Designed as a tool for ship owners and operators,
Flagship-EEM supports the crew in making more efficient use of
energy on board. Due consideration is given to both the main
and auxiliary engines ensuring propulsion and electrical
economies are evaluated. It provides transparent information
about the current energy use and increases awareness for options
to improve efficiency. Flagship-EEM enables comparison of
current consumption to baseline consumption and recent history
and establishes a database of operational data for evaluation of
operational measures and changes in machinery.
To date most ships have not been equipped to measure
and display actual power consumption and as a result
crews tend to run vessels at too high consumption patterns.
When the Flagship-EEM development team started looking
into how vessel efficiency could be improved no detailed
consumption data was actually available. They had to
undertake a detailed analysis of on board power consumption
in order to determine efficiency influencing parameters. They
also collected operational data over time to ensure that any
external influences and variations were considered to ensure
modelling accuracy especially in relation to predicting
potential fuel savings.
Dr. Gerd Würsig, deputy head of department at Germanischer
Lloyd Environmental Research and project manager for
Flagship-EEM said: "Flagship-EEM makes energy monitoring
possible without the need to install highly accurate fuel flow
meters. It is also unnecessary to access proprietary engine data
which manufacturers are generally unwilling to disclose -- this is
a significant development".
Malte Freund, project engineer at Germanischer Lloyd
commented: "The system has been trialled on board a
multi-purpose vessel since May 2010 during which time
indications have been positive and a whole range of small,
hidden energy saving opportunities have been identified. Offline
evaluation of the data indicated significant potential savings
could be made by improved machinery operation and more
As an example, the data indicated that a saving of some 500
running hours per year could be achieved combined with
improved fuel economy, simply by turning off diesel generators
that were unnecessary to the ship's actual power requirements.
Flagship-EEM's monitoring of the air compressors also
highlighted higher than expected running time. Further
investigation identified leakages in the pressurised air system
which, when repaired, would lead to operational savings.
"Germanischer Lloyd has been sufficiently impressed with
performance to have patented the method for energy and fuel
consumption evaluation and we have incorporated specific learning
from this project into products for launch later this year."
Mr Herman de Meester, Coordinator of Flagship commented:
"The adoption of specific learning in to new products for the
advancement of the industry is exactly what EC projects such as
these are all about. Flagship-EEM delivers environmental and
commercial advantages to the maritime transport industry
delivering the Flagship mission."
Mr de Meester continued: "Flagship-EEM works in parallel with
current initiatives such as the IMOs energy efficiency design index
(EEDI). EEDI currently addresses new vessels only, while
Flagship-EEM is applicable to both new and existing vessels ensuring
that energy efficiency can be optimised in both situations".
The Flagship--EEM project was led by Germanischer Lloyd and
was supported, delivered and trialled in conjunction with
Reederei NSB in Germany; Marintek and Teekay Shipping in
Norway; Danaos Shipping of Greece, Rolls Royce in the UK and

Flagship-EEM enables reduction in fleet-wide fuel consumption
The Flagship-EEM system, developed by a number of prominent partners led by Germanischer Lloyd, has been trialled since May 2010 on a multipurpose
vessel (top left). The system allows constant monitoring of power plant to maximise fuel efficiency without having to install highly accurate fuel flow meters
or access proprietary engine data. The trials indicate potential savings of 500 running hours per year.
