We are pleased to share a technical article authored by our customer, Penta-Ocean, highlighting the first successful offshore fabrication of reinforced concrete (RC) caissons in Japan using our gantry-based slipforming method on a floating dock. This innovative approach reduced construction time dramatically — from several months to just 8–9 days per unit.
In the article, the authors discuss:
- The development of a digital application that automatically calculates the required retarder dosage to maintain consistent concrete setting despite significant temperature fluctuations.
- How slipform technology was applied to construct large RC caissons offshore.
- Innovative methods for monitoring and controlling early-age concrete strength and quality.
- Key lessons learned from Japan’s first full-scale offshore project utilizing this construction method.
The project highlights how digitalization, advanced concrete technology, and innovative construction methods can deliver substantial efficiency gains in complex marine infrastructure projects.
We thank Penta-Ocean for sharing their experience and expertise, and we are proud to make this article available through our website.
