Offshore foundation (JoHyun)

• • Pipe cutting technology within the utility tunnel has been developed for long-term maintenance & management

  • Three alternatives (waterjet cutter, laser cutter, and diamond wire saw) were compared under six evaluation citeria, using AHP

  • Ultimately, prototype of pipe cutting tool within the utility tunnel has been suggested
