Port and Harbor Development

Specialized domain

  • We provide comprehensive port and harbor development such as planning, survey, basic design, detailed design, application for permits and licenses, and maintenance of harbor facilities (channel, mooring basin) and protective facilities (breakwater, sea wall, embankment), mooring facilities (quay wall, pier, floating pier) for port, harbor and fishing port. (For domestic projects)

Services

  • Followings are example of our services.
  • Wave analysis: Capable of wave analysis according to waters characteristic, and to layout planning of reclaimed land and breakwater.
    • Takayama method: Wave analysis method which is specialized for the wave height distribution in small harbor.
    • Energy equivalent method: Wave analysis method which in specialized for refraction calculation affected by water depth difference.
    • Boussinesq method: One of the most practical wave analysis methods which can precisely solve the motion of water, at port where the behavior of wave simultaneously changes, due to the difference of complex topography, the point where the non-linearity of wave and behavior of breaking wave are not negligible.

Result of Boussinesq Method【Example】

  • Calculation of construction cost: Channel dredging, facility development (Reclaimed revetment, Unloading pier for charcoal, Creation of land, Belt conveyor, etc.).
  • Mooring simulation: Based on specification of mooring facilities, vessels, and mooring procedure, we simulate the motion of moored vessels in order to evaluate the limit operation wave height and the safety of bollard and fender.
  • Field inspections: Maintenance inspection and investigation using techniques combining UAV and multi-beam depth sounders to measure seawalls.
