Innovative 2,500 TEU Container Vessel Receives AiP from Bureau Veritas

The “Trade Wings 2,500”: an innovative container ship with a capacity of 2,500 TEU (Twenty-Foot  Equivalent Unit), designed jointly by VPLP Design (France), Alwena Shipping (France), SDARI (China)  and AYRO (France) has received Approval in Principle from Bureau Veritas. With an overall length of  197m and a breadth of 32m, the vessel offers a deadweight of 32 500 m tons.  

It fosters the combination of a wind-assisted propulsion with six Oceanwings® with an LNG-electric  propulsion with pods. The wingsails are installed on a vertical sliding mechanism to retract them partially  while the vessel is in port, thus minimizing the impact on cargo operations. The LNG storage tank is  based on GTT’ Mark III containment system and the LNG power plant is designed with pure gas 4-strokes  gensets only. This architecture is a flexible platform offering possible upgrade to decarbonated fuels in  the future such as Ammonia or Hydrogen.  
Suitable to short sea shipping operations or feedering in Europe, Central America, Caribbean Islands and  China, the Trade Wings 2,500 can also operate on transatlantic trades. The design minimizes time in port  operations, as maneuverability is increased with the Pods, and the hatch coverless design further speeds  up cargo operations.  
On a typical transatlantic route of 4,000 Nm, the Trade Wings 2,500 will save on average 35% CO2- equivalent emissions compared to a conventional design, with a 2-stroke engine, single shaft and without  wingsails, at the same speed. Out of these 35% savings, the Oceanwings® accounts to 57%, the  optimized LNG thermal propulsion delivering the remaining 43% savings.  

This co-work to design the Trade Wings 2,500 sets the pathway for what could be the low emissions  container vessels of the near future.  
After reviewing the key drawings, on the 12th of May 2021, Bureau Veritas Marine & Offshore granted an  Approval in Principle to the Trade Wings 2500 ‘ basic design. 

Alex Gregg-Smith, Senior Vice-President Bureau Veritas for North Asia said: “Wind-assisted propulsion  is a high-potential solution that can contribute to the long-term decarbonization of the marine industry.  We have just released new wind propulsion system rules – and this innovative design, approved in  principle by BV, including a sliding mechanism, demonstrates the feasibility of wind-assisted propulsion  on board container ships with deck space limitations. Benefitting from a coverless hatch and LNG electric  pod propulsion, the design provides both operational flexibility, improved efficiency and reduced carbon  emissions, complying with, or exceeding, regulatory requirements. Bureau Veritas continues to address  the challenges of the energy transition by providing solutions to the safety, risk and performance  requirements for innovation in future fuels and propulsion systems.”
