BV Awards AIP Certificate for Sunrui Marine Environment's Marine Wind Rotor Assist System

Bureau Veritas Marine & Offshore (BV), has recently awarded Approval in Principle (AIP) Certificate to Sunrui Marine Environment Engineering Co. Ltd. (Sunrui Marine Environment)for its Marine Wind Rotor Assist System. The marine wind rotor assist technology, a highly promising carbon reduction solution for the shipping industry, provides auxiliary propulsion via aerodynamics, significantly reducing fuel consumption and carbon emissions.

Sunrui Marine Environment’s technological breakthroughs in marine wind energy utilization have drawn wide attention: its developed system overcomes key technologies such as lightweight composite outer cylinder manufacturing, efficient drive control, and intelligent energy-saving optimization, suitable for both newbuilds and retrofits of existing vessels.

BV’s technical expert team conducted a comprehensive review during the certification process, covering system principles, structural safety, equipment layout, and risk control systems. Special focus was placed on verifying operational safety and emission reduction effectiveness in real-ship applications, ultimately confirming the system fully meets classification society regulations.

This certification not only recognizes Sunrui Marine Environment’s technological innovation but also underscores BV’s commitment to advancing the shipping industry’s sustainable transition. Amid the global acceleration of shipping decarbonization, BV’s technical audits balance innovation with safety — ensuring emerging technologies like wind assist achieve both emission reduction goals and maritime safety standards through end-to-end evaluations.

As the International Maritime Organization (IMO) tightens carbon reduction requirements, auxiliary propulsion technologies (e.g., wind, photovoltaic) are becoming focal points of industry transformation. BV supports this transition through certification, standards, and collaboration, and will continue partnering with stakeholders to advance low-carbon shipping and realize a zero-carbon future.
