Improvement and expansion of port facilities at Kardamena, Kos

Project location

Kardamena port is situated at the south side of Kos island, in front of the homonymous village.

The existing port facilities berth predominantly recreational and passenger vessels and to a lesser extent fishing or military boats. The main issue which currently undermines the port is related to the lack of the existing infrastructure as well as the absence of an operational plan.


Following a tender process, CNWAY was commissioned in October 2017 by the Municipal port Authority of Kos to proceed in a timely manner with the above study.

Project scope

1st Stage:

  • Topographic - bythometric survey
  • Preliminary design of port works
  • Sediment transport study
  • Wave disturbance study
  • Final study of E/M
  • Feasibility study

2nd Stage:

  • Environmental Impact Study (EIA)
  • Geotechnical survey

3rd Stage:

  • Detailed design of port works
  • Electromechanical detail design
  • Tender documents

Project facts

  • Estimated construction cost is € 9,740,000, including electromechanical and building infrastructure.
  • Construction of windward and leeward breakwater to provide a reduced wave climate within the basin while minimizing the extent of sedimentation
  • Separation of different port uses with emphasis on operational autonomy and quality upgrade of the services provided
  • Zone allocation for passenger vessels with a capacity of 8 boats
  • Zone allocation for fishing vessels with a capacity of 32 boats
  • Zone allocation for recreational vessels with a capacity of 159 vessels
  • Sediment bypass to maintain sediment budget

Supportive studies

In order to address the sedimentation problem of the port and to assess the impact of the proposed works, as defined in the preliminary design, to the coastline, the project included a sediment transport study.

In order to investigate and evaluate the effects on the existing wave disturbance from the construction of the proposed projects, a wave disturbance study was carried out.
