SAFETY4SEA: Your organization has been shortlisted for the 2019 GREEN4SEA Awards in the ‘Technology’ category alongside a number of other distinguished nominees. What would you like to share with industry’s stakeholders with respect to this development?  

Chryson Sariyannidis: Today, it is of outmost importance for shipping to design efficient and cost effective methods for the supply of both the ships and the industry with the most environmentally friendly fuel (Natural gas).


S4S: What is the key feedback from your existing & prospective clients on the barriers and drivers towards investing into your technology?

Chr. S.: Drivers: The project has been proven to be and widely accepted as a highly competitive approach for the transportation of Natural Gas from its source to consumer.

Barriers: Current market, primarily for short to medium distances and quantities, is presently under development.


S4S: Do you have any new projects on the pipeline and/or plans that you would like to share with the rest of the industry?

Chr. S.: Yes. Preliminary designs for the storage and transportation by sea of Natural Gas in compressed form (CNG) have been completed including an autonomous CNG Carrier equipped with compressing/loading/discharging facilities, for which an approval in principal has been obtained by the American Bureau of Shipping (ABS). Furthermore, studies for the design of the most efficient and cost effective facilities of CNG storage ashore, are presently in progress.

Additionally, an agreement of a ‘Joint Development Project’ (JDP) for Natural Gas Transportation by Sea has been signed in January 2019 between: - CS & Associates SA, the American Bureau of Shipping – ABS, the National Technical University of Athens, Ariston Navigation Corp. and George Moundreas & Company SA.


S4S: If you could change one thing about the shipping industry, what would it be and why?

Chr. S.: The elimination of liquid fuels and their replacement by Natural Gas since it is the most environmentally friendly fuel from all the natural sources. Additionally, it is safer than any other fuel since it is lighter than the air and in case of a leakage the hazards are substantially reduced as it will flow high in the atmosphere. It is also to be noted that leading automobile manufacturing companies are designing vehicles to operate with Natural Gas, in addition to electricity. For a most efficient environmental protection, the liquid fuels are being gradually eliminated.


S4S: What is your key message to the industry for a more sustainable future of shipping?

Chr. S.: Use natural gas as a fuel. Apart from being the most environmentally friendly it is also less expensive.
