Double-Use Off-Shore Meteorological Tower with Three-Leg Suction Pile Foundation-Video

Video Transcription

Video Summary

ADVECT presented a case study on reusing a 97-meter offshore meteorological tower supported by three suction piles at two sites off South Korea. The tower was assembled onshore, transported and installed as a single unit, then retrieved by injecting water into the piles and reinstalled at a second site. Its three-leg design and streamlined upper structure reduced wave loads and overturning forces, while suction-pile foundations enabled straightforward installation and retrieval. The first installation took about one day offshore; retrieval and reinstallation took roughly seven days in total. Reusing the structure avoids building a new tower and reduces decommissioning waste. The project achieved estimated savings of 34% in cost ($4.2 million) and 48% in time for use at two locations. Further reuse could increase savings, demonstrating the technical and environmental benefits of suction-pile structures.
