Αυξάνοντας την περιβαλλοντική επίδοση της ναυτιλίας - τάσεις και προοπτικές
Increasing the environmental performance of the maritime industry - trends and perspectives
Δεμοιράκου, Μαρία - Ευαγγελία
The transportation, storage and use of liquefied natural gas (LNG), on modern ships, ballast treatment and management methods, marine gas emission regulations are ways to manage the environmental impact of shipping and reducing the imprint of all relevant functions and processes in the environment. Similarly, environmental management and quality certification plans, ecoports, and zero emission ships are the latest environmental practices used to reduce the impact on the general environment. Nowadays, it is a fact that more and more new environment-friendly forms of energy are used, in order to reduce the greenhouse effect and its contribution to the destruction of the environment. For this reason, maritime specialists focus on the use of natural gas as a fuel on board ships. The rapid development of technology helps to make this a reality, since liquefied natural gas needs special attention to its transportation in order to maintain it. New port infrastructure and modern gas-fired boats have also been created, for coping with the required conditions. Modern ships include new internal combustion engines, which can use this fuel as a means of propulsion. They have two types of storage tanks, which keep the natural gas in liquid form and at -162⁰C to carry more volume.
