Recently, the Matchmaking Conference for the Ocean Decade Marine Eco-Restoration Achievements was held in Qingdao, where the project “Key Technologies and Applications for Integration of Sessile Organism Corrosion Prevention and Ecological Restoration in Marine Concrete Engineering” was honored with two prestigious awards. Led by Professor LÜ Jianfu from the College of Aerospace and Civil Engineering at Harbin Engineering University (HEU), the project was selected as a Major Project under the Ocean Decade China Initiative International Cooperation Seed Fund in the Innovation Technology track of the inaugural UN Ocean Decade Marine Eco-Restoration Competition. Additionally, it was named an Outstanding Project in the competition. As the only university from China to lead a project in this track, HEU was invited to present an on-site roadshow.

On-site Roadshow Presentation

The competition, organized by the United Nations as part of the Ocean Decade initiative, features three main categories: Innovation Technology, Practical Cases, and University Students. It aims to identify innovative and systemic solutions in marine eco-restoration, highlight practical cases with demonstrative value, and promote the harmonious coexistence of humans and the ocean to build a healthier and more resilient marine ecosystem.

Concrete Specimens with Densely Attached Oysters

Professor LÜ’s team has pioneered a world-first integrated technology that combines marine concrete engineering durability with marine eco-restoration, specifically utilizing marine sessile organisms such as oysters. This groundbreaking approach has led to the creation of a new paradigm for “engineering-ecology synergistic coexistence.”

The Team Conducting Offshore Coating Application

The ecological concrete, cement-based coatings, and oyster attachment substrates developed by the team exhibit remarkable properties, including high-efficiency anti-corrosion and ecological restoration capabilities. Industry experts have described the technology as “a revolutionary marine engineering anti-corrosion solution that challenges traditional approaches.”

The project has earned four prestigious awards, including the Gold Award for Patents in the Shipbuilding and Marine Engineering Industry, and has been granted 27 authorized invention patents.
