Floating breakwater in Messolonghi, Greece

 

FDN was asked to design and construct a floating breakwater structure for Messolonghi harbour. It means that complete range of services were provided for this project starting with own wave analysis, through complete design up to construction and final installation. The last part of the whole process was monitoring of the structural behaviour under extreme weather conditions.

 

Design criteria for the structure were the following:

• Water depth near breaker 9m

• Wind speed 12 Beaufort (30 m/s)

• Occurring wave periods T =1 to 6 sec , corresponding wave lengths up to 60m

• Wave height up to 2m (significant wave height)

• Wave damping needed: up to 2m waves with a period of 5s should be damped up to 80%. Higher                  waves damped 50%

• Design extreme condition wave height up to 4m (for design anchorage, concrete and connections)

• Design life structure 70 years

• Reference period of loads 100 years

 

The structure was calculated according to the European codes.
