- Hung Ze Shipping will equip its new chemical tankers using route optimization technology from Finnish firm NAPA
- The first vessel with the rotor sail system is expected by late 2025 marking Dealfeng’s first overseas commercial contract.
- Dealfeng’s wind-assisted propulsion offers 5%–25% fuel and carbon emission reductions.
Singapore-based shipowner Hung Ze Shipping has entered into a cooperation agreement with Chinese company Dealfeng New Energy Technology to equip a new series of 14,000 dwt chemical tankers with wind-assisted rotor sails.
Wind-Assisted Rotor Sails Set to Improve Fuel Efficiency on New Chemical Tankers
Hung Ze Shipping plans to install Dealfeng’s 5m by 24m rotor sails on the forecastle decks of its upcoming 14,000 dwt chemical tankers. By partnering with Finnish maritime software firm NAPA, the companies aim to enhance the benefits of wind-assisted propulsion through advanced route optimization, which is expected to maximize fuel savings and reduce emissions while improving overall energy performance. The first vessel equipped with the rotor sail system is anticipated to be delivered in the fourth quarter of 2025. According to preliminary estimates shared by Dealfeng, the technology could reduce fuel consumption by about 8% on typical trading routes.
Earlier this year, Dealfeng secured multi-million RMB funding in a Pre-A Series round, backed by TZME (TianJin), a company active in mechanical equipment manufacturing. This partnership will focus on the design, production, and market expansion of wind-assisted propulsion systems, targeting an annual output of 50 Rotor sails.
Dealfeng’s system leverages the Magnus effect to capture wind energy and provide auxiliary propulsion tailored to various ship types, offering fuel and carbon emission reductions ranging from 5% to 25%.
