First Batch of 8 Electric Official Vessels Enters Service on the Yangtze, Marking the Deployment of TRI WATER's Smart Law Enforcement Solution

Yangtze's First 'Diesel-to-Electric' Official Vessels Officially Commissioned

On December 23, with the successful completion of the delivery and acceptance inspection for the "Haixun" series vessels, the green conversion project for the first batch of eight 30-meter-class official patrol vessels on the Yangtze River—jointly developed by Wuhu Shipyard and TRI WATER New Energy—was successfully concluded. All eight vessels, namely "Haixun 12518," "Haixun 12527," "Haixun 12523," "Haixun 12513," "Haixun 12530," "Haixun 12512," "Haixun 12517," and "Haixun 12918," have been formally commissioned into frontline service for the Yangtze Maritime Safety Administration.

This batch conversion of official vessels to electric power represents a practical implementation of the national "dual carbon" strategy by Wuhu Shipyard and TRI WATER New Energy, and serves as a key initiative in response to the Yangtze River Administration's "Electrification of the Yangtze" proposal, supporting the green development of the Yangtze River Economic Belt.

Leveraging Wuhu Shipyard’s deep-seated technical expertise in special vessel manufacturing and TRI WATER New Energy’s core propulsion technology strengths, the project was tailored to precisely match the characteristics of the 30-meter-class vessel type and the operational demands of Yangtze maritime law enforcement. Through multiple rounds of solution iteration and optimization, a comprehensive quality control system spanning the entire process—from R&D and component integration to installation and commissioning—was established.

This conversion focused on a core electrification upgrade, comprehensively replacing the traditional diesel propulsion and power supply systems with a pure battery-powered DC grid propulsion system. Simultaneously, cabin functionality was optimized and the hull structure was upgraded. While strictly complying with maritime regulatory requirements, the modifications maximized the vessels' practicality for daily operations, paving the way for the large-scale electrification of inland official vessels. The retrofitted ships offer significant advantages including zero emissions, low noise, and high efficiency. This not only enhances the ecological profile of the Yangtze "Golden Waterway" but also fills a technical gap in the large-scale electrification of inland official vessels, setting a demonstrative benchmark for the green upgrade of inland waterway transport tools nationwide.

TRI WATER’s New-Generation “Smart Law Enforcement” Solution

At the recently concluded 2025 Shanghai International Maritime Exhibition, Wuhu Shipyard and TRI WATER New Energy, targeting the future 60-billion-yuan smart law enforcement market and addressing current pain points in maritime law enforcement, grandly unveiled their new-generation "1+4+5+N" integrated smart law enforcement platform solution.

"1" represents one intelligent equipment platform: Newly developed primarily for waterborne regulatory agencies such as the Yangtze River Administration and the Yangtze Maritime Safety Administration, it employs a fully electric drive. The vessel measures 33.35 meters in length, with a beam of 6 meters and a depth of 1.9 meters. It is equipped with a 965 kWh lithium iron phosphate battery, utilizes a charging mode, and has a designed range of 100 km.

"4" operational domains: It provides comprehensive product combinations and solutions for four operational domains: space-based, air-based, land-based, and sea-based.

"5" key technologies: Focus is placed on tackling five major key technological areas: multi-modal power systems, hull form optimization, intelligent sensing, cross-domain connectivity, and intelligent decision-making systems.

"N" application scenarios: It serves N application scenarios, including inland waterway law enforcement, emergency response, rescue operations, and scientific research. It pioneers new scenarios for integrated land-water law enforcement and monitoring, configures unmanned aerial and surface platforms, and achieves seamless integration between water transport and the low-altitude economy.

With this, TRI WATER New Energy has taken the lead in completing the comprehensive layout of an inland smart law enforcement platform. Following the demonstrative application of electrified public service vessels, it will continue to lead the electrification and intelligent transformation and upgrading of vessels in the public sector. This contributes further to promoting the high-quality development of inland waterway shipping and to building a green Yangtze where humanity and nature coexist in harmony.
