Design and Construction of the Large Concrete Floating Pier at Incheon Harbor

Abstract

There are two 200 m long floating piers for berthing car ferries at Incheon harbor, South Korea. Each floating pier has almost same dimensions but these piers are made of steel and concrete, respectively. This paper focus on the design and construction of a concrete floating pier. In the design, it was proposed as an alternative instead of a steel floating pier having two inner moorings and separated three parts (L: 66 m × 3 ea). So it was composed of only one structure (L: 200 m) without inner mooring dolphins, not only to maximize the use of top-side space but also to minimize the number of mooring dolphins. In the construction, the modular construction method fabricating concrete segments on land and assembling them as modules on the seawater was applied instead of the conventional method using a big floating dock not only to increase the construction efficiency but also to enhance the concrete quality of modules.
