Battery Drive Systems
Greenhouse gases released during the burning of fossil fuels pose a great danger to our world. Increasing levels of carbon dioxide (CO2), methane (CH4), diazot monoxide (N2O) and ozone (O3) gases in the atmosphere cause the greenhouse effect. With the greenhouse effect, the temperature of the earth's atmosphere and earth's crust is increasing, and the worst consequence of this unnatural increase in the coming years is the rapid melting of glaciers. International organizations and organizations carry out various projects on this issue and states allocate resources for all these.
Among the 2030 Sustainable Development Plans of the United Nations, the goal of “zero emissions in the seas” was included. In addition, due to the flag state rules introduced to protect the world's environmental heritage of the sea and coasts, especially led by Norway, passenger ships and ferries going to these regions have started to be required to operate with clean energy. In order to preserve the natural beauty of Turkey's coasts, the benefits of encouraging and increasing the number of ships operating on clean energy will be seen in the future.
With the impact of this decision and developing technology, the demand for electricity storage and management systems (ESS - Energy Storage System) is increasing day by day. Lower maintenance costs and infrequent maintenance intervals in renewable technology, as well as the increasing global demand for clean energy, have signaled a change in the maritime industry, and important steps have been taken to ensure that the systems used in marine vessels are completely provided with electricity storage units.
The electric storage unit consisting of lithium-ion cubes used in marine vessels is defined as ESS (Energy Storage System). ESS systems are a modular battery power source developed for general marine use. ESS can be applied to high and low voltage, AC and DC power systems. It can also be combined with various energy sources such as diesel/gas engines and fuel cells and can be designed with hybrid operation. The benefits of ESS systems used in marine vessels are; low maintenance cost and infrequent maintenance requirements, high efficiency, reliable operation, reduction of air and marine pollution, energy management, traceability in all conditions and integration with smart systems.
World's First Battery Powered Zero Emission Tug Zeetug Classified by Türk Loydu
At this stage, Türk Loydu started to develop its own rules for lithium ion battery propulsion boats and carried out the classification activities of the Zee TUG project, which was produced for the first time in the world to provide trailer service with battery (electric) propulsion.
Conventional propulsion systems are being replaced by electric propulsion, battery propulsion, propulsion from renewable energy sources and hydrogen fuel cell propulsion. Energy sources such as lithium batteries that do not emit harmful emissions, high charge capacity capacitors, renewable sources and hydrogen fuel cells have started to be used in application projects. Türk Loydu Uyg. Deg. A.Ş. (TL) closely follows these developments in the maritime sector. In order to meet the classification and product certification needs of the sector, it prepares rule sets for these systems. The rules are formulated in the light of relevant international and national standards with the main objective of ensuring the safety of life, property and the environment. Currently, TL has published guidelines for the use of battery propulsion systems and fuel cell propulsion systems on board ships. These publications are being revised according to the developments in the sector and inputs obtained from usage experiences.
TL is the most important and national guarantee for the maritime industry to obtain conformity assessment checks from independent, impartial and reliable sources. Having successfully carried out the classification activities of the diesel-electric propulsion military ships, which are involved in the defense of the Blue Homeland and for which export contracts have been signed to friendly countries and their production has started, TL's quality engineering consultancy service with battery-powered Electric Tug Boat classification activities is just one of the achievements that our country has put forward to closely follow and lead the developments in the sector.
In the coming periods, the certification of battery systems, the change in battery technology and the classification of battery-powered small passenger boats and large passenger ferries in parallel with the increase in battery power are among the issues that TL is meticulously focusing on.
