A Chinese-flagged bulker fitted with a domestically developed rotor sail took to the water at the No. 2 wharf of CSSC Chengxi Shipbuilding Co., a subsidiary of China State Shipbuilding Corporation, marking a solid step forward in the practical application of wind-assisted rotor technology developed in China, reports JEC.

The 45,000 dwt bulker Chang Hang Sheng Hai, built-in 2012 by Bohai Shipbuilding Heavy Industry Co, is owned by Minsheng Financial Leasing and operated by Shanghai Ming Wah Shipping, data from VesselsValue shows.

The Handysize bulker has been fitted with four rotor sails. The installed rotor sails boast a diameter of 3 meters and an overall height of 24 meters, respectively. By incorporating wind-assisted rotors, the vessel is expected to achieve energy savings of over 5% while significantly reducing carbon oxide emissions during navigation.

The rotor sail harnesses wind energy to augment a ship’s propulsion and holds great potential for achieving energy savings in bulk carriers and large oil tankers.
