Effective positioning of submerged tunnel segments

For the construction of the Busan-Geoje tunnel, Strukton was awarded the construction, immersion, and accurate positioning of tunnel segments. The crucial importance of the accurate positioning of tunnel segments required the development of a Tunnel Segment Measurement System (TSMS).
For the actuation of a hydraulic cylinder – required to provide a constant pressure – and to drive a small constant tension winch, a 200-watt subsea hydraulic power pack was installed on each measurement unit.
