Core Viewpoint - China Dredging Environmental Protection (00871) reported a revenue of 146 million yuan for the first half of 2025, representing a year-on-year decline of 11.2% [1] - The loss attributable to the company's owners narrowed to 21.28 million yuan, a decrease of 32.5% compared to the previous year [1] - Basic loss per share was 1.42 cents [1] Revenue Breakdown - The infrastructure and reclamation dredging segment recorded revenue of approximately 19.3 million yuan, which is an increase of 150% compared to the same period in 2024 [1] - The revenue growth in the infrastructure and reclamation dredging segment was primarily due to an increase in projects undertaken by the group during the reporting period [1]

Core Viewpoint - The "Junlan" vessel, designed and built in China, is the world's largest all-electric, detachable, environmentally friendly dredging ship, specifically tailored for the management of the Guanting Reservoir [1][2]. Group 1: Vessel Features - The "Junlan" vessel is equipped with a fully electric-driven excavation system, featuring a 600 kW cutter head that can dredge 2,000 cubic meters per hour, which is three times more efficient than traditional equipment [2]. - It incorporates an intelligent control system that optimizes operational parameters based on soil conditions, allowing for remote control and precise adjustments of output power [2]. - The vessel is designed for low carbon emissions, utilizing a high-pressure shore power connection and a new type of environmentally friendly cutter that minimizes disturbance to surrounding water bodies, achieving "zero leakage excavation" [2]. Group 2: Project Impact - The completion of the dredging project will significantly enhance the self-purification, flood control, power generation, and water supply functions of the reservoir [2].

Core Viewpoint - The introduction of the "Junlan" environmentally friendly dredging vessel marks a significant advancement in the dredging industry, particularly for the ecological restoration and management of the Guanting Reservoir, which has accumulated 650 million cubic meters of sediment over time [1][2]. Group 1: Vessel Features and Technology - The "Junlan" vessel is the first in the "river-lake" dredging equipment sector to utilize a fully electric drive excavation system, featuring a cutter power of 600 kilowatts [1]. - The dredging efficiency of the "Junlan" is three times that of previous equipment, achieving a standard dredging volume of 2,000 cubic meters per hour, equivalent to emptying a standard swimming pool every hour [1]. - Designed specifically for deep water lakes, the vessel can excavate to a depth of 25 meters, and with additional deep-water modules, it can reach a maximum depth of 60 meters, ensuring precise dredging of contaminated sediment without disturbing surrounding water bodies, achieving "zero leakage excavation" [1]. Group 2: Project Impact and Goals - The Guanting Reservoir dredging pilot project aims to remove 11.5387 million cubic meters of contaminated sediment, addressing various technical challenges such as deep excavation, complex soil conditions, long transportation distances, and high environmental standards [2]. - The completion of the dredging project is expected to significantly enhance the self-purification capacity of the Guanting Reservoir, improve water quality, and strengthen the reservoir's flood control, power generation, and water supply functions, thereby supporting the ecological and economic development of the Yongding River basin and laying a solid foundation for restoring the capital's strategic water source functions by 2035 [2].
