‘Project Forward’ is led by Athens-based Arista Shipping.
Wärtsilä, a global leader in advanced technologies and complete lifecycle solutions for the marine and energy markets, is going to join up with an international group of shipping industry companies and organisations in a project to develop a concept for equipping future dry bulk carrier vessels with LNG propulsion.
‘Project Forward’ is led by Athens-based Arista Shipping. It officially commenced in May 2015 with the aim of developing a commercially feasible LNG-powered dry bulk carrier design capable of complying with the International Maritime Organization’s (IMO) Energy Efficiency Design Index 2025 standards, as well as with all relevant emission reduction regulations.
In addition to Arista Shipping, the other parties involved in the project are Finnish ship designer Deltamarin, the Houston based classification society American Bureau of Shipping (ABS) and GTT, the French LNG membrane containment system designer.
The Wärtsilä 31DF dual-fuel engine is likely to form the basis of the concept’s propulsion system. Introduced in June 2015, the Wärtsilä 31 has been recognised by Guinness World Records as being the world’s most efficient 4-stroke diesel engine. It is available in 8 to 16 cylinder configurations and has a power output ranging from 4.2 to 9.8 MW, at 720 and 750 rpm. The DF version allows the use of either LNG or conventional marine fuel oils. While 2-stroke engines are the conventional choice for vessels of this type, the efficiency of the Wärtsilä 31 engine makes it a competitive and viable alternative option.
“Wärtsilä has been selected to participate in this important project because of our depth of experience in LNG propulsion solutions, our strong position in 4-stroke engine technology, and in particular because of the state-of-the-art Wärtsilä 31 engine. This engine has not only taken efficiency to a new benchmark level, but in gas-mode is IMO Tier III compliant without the need for any exhaust cleaning systems. We are proud to be a part of this future-looking project, which could eventually be applied equally well to other types and sizes of merchant vessel,” said Aaron Bresnahan, Vice President, Sales, Wärtsilä Marine Solutions.
Arista Shipping Principal, Alexander P. Panagopulos, added: “Project Forward aims to become a milestone for the shipping industry and in particular for owners and operators of cargo ships. Owners must decide within the next 5-10 years whether gas as fuel is a practical means of compliance with lower emissions standards and this project will enable all of us to understand its feasibility. We welcome Wärtsilä’s involvement, as it is a company with great experience in this field.”
