AIP approval for Wind-Assisted Containership from BV: France-China partnership!

The latest concept to be advanced is for a short sea or feeder containership that combines wind with an LNG power plant and advancements in design to create a more efficient vessel. Known as Trade Wings 2500, the design has been awarded an Approval in Principle (AiP) from Bureau Veritas.

The concept is for a containership with a capacity of 2,500 TEU. It is a combination of wind-assisted propulsion with six Oceanwings and LNG-electric propulsion with pods. The wing sails are installed on a vertical sliding mechanism to partially retract while the vessel is in port to reduce interference with cargo operations. The LNG storage tank is based on GTT’ Mark III containment system and the LNG power plant is a 4-strokes gensets. It is a flexible platform that would make it possible to transition to future fuels such as Ammonia or Hydrogen.

According to the designers and BV, the Trade Wings 2500 will save on average 35 percent CO2-equivalent emissions compared to a conventional design. Their calculations were made based on a typical 4,000 nautical mile transatlantic route comparing the Trade Wings operating at the same speed to a convention ship with a 2-stroke engine, single shaft, and without wing sails. The Trade Wings’ Oceanwings accounts for 57 percent of the reduction with the optimized LNG thermal propulsion delivering the remaining 43 percent of the reduction in emissions.

“Wind-assisted propulsion is a high-potential solution that can contribute to the long-term decarbonization of the marine industry,” said Alex Gregg Smith, Senior Vice-President, Bureau Veritas North Asia.

Created in a partnership between French firms VPLP Design, Alwena Shipping, and AYRO, and the Chinese Shanghai Merchant Ship Design & Research Institute (SDARI), the concept is for a 32,500 dwt containership. It would measure 646 feet in length with a beam of 105 feet.
