Bureau Veritas Grants AIP Certificate to Sunrui Marine Environment’s Wind Rotor Assist System

Bureau Veritas Marine & Offshore (BV) has awarded an Approval in Principle (AIP) certificate to Sunrui Marine Environment Engineering Co. Ltd. for its Marine Wind Rotor Assist System. This innovative system is designed to provide auxiliary propulsion using aerodynamic principles, helping reduce fuel consumption and lower carbon emissions in maritime operations.

Sunrui’s wind-assisted propulsion technology has gained attention for addressing several technical challenges. The system features a lightweight composite rotor, a high-efficiency drive and control system, and intelligent energy-saving optimization. It is adaptable for both newbuild vessels and retrofit projects, making it a versatile solution for greener shipping.
