Designed as a tool for ship owners and operators, the development of the FLAGSHIP-EEM (Energy Efficiency Monitoring) system enables data acquisition and analysis to continuously evaluate power requirements at every stage of a vessel’s voyage.
The system monitors main and auxiliary engines, ensuring propulsion and electrical economies to improve fuel consumption that can reduce both operational costs and environmental impact.
Supporting the crew in making more efficient use of energy on board, the system provides details of current energy use whilst increasing awareness of options to improve efficiency. It also allows comparison of current consumption to baseline consumption and recent history, establishing a database for evaluation of operational measures and changes in machinery.
To date most ships have not been equipped to measure and display actual power consumption, as a result crews tend to run vessels at too high consumption patterns.
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, which is a significant development”.
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 data evaluation indicated significant potential savings could be made by improved machinery operation and more timely repairs.
One such example is a saving of some 500 running hours per year that could be achieved combined with improved fuel economy, simply by turning off diesel generators that were unnecessary to the ship’s actual power requirements.
Germanischer Lloyd said that it had been sufficiently impressed with the system’s performance to have patented the method for energy and fuel consumption evaluation and had 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 into new products for the advancement of the industry is exactly what EC projects such as these are all about, to deliver environmental and commercial advantages to the maritime transport industry”.
“Working in parallel with current initiatives such as the IMO’s energy efficiency design index (EEDI), which currently addresses new vessels only, FLAGSHIP-EEM is applicable to both new and existing vessels ensuring that energy efficiency can be optimised in both situations,” he continued.
FLAGSHIP–EEM is a part EU-funded maritime transport project 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 Co Ltd of Greece, Rolls Royce in the UK and Wärtsilä Finland Oy of Finland.
