A steel reinforcing box beam was installed underwater on a steel pipe pile supporting the deck for the purpose of protecting the crude oil piping of Seaverse. Under the severe conditions such as the narrow part close to the crude oil pipe just below the deck and the stormy weather, we examined and carried out the efficiency of construction and completed the construction within the construction period.
