Witteveen+Bos designs new seaport Taman


An entirely new port on the Black Sea coast near Taman (Krasnodar) is the first step towards fulfilling the Russian government’s ambitious plans to expand and modernise the country’s network of international seaports.

The strategically located port is expected to become one of the Russian Federation’s three largest ports. Within a few years it is likely to be handling about 100 million tonnes of cargo. The main types of cargo will be dry bulk (like coal, fertilisers and iron ore). But the plans also include terminals for general cargo (steel products) and containers.

The port has about nine kilometre quay length, with total quay area of about 260 ha. The port is protected by two breakwaters with a total length of 7.5 kilometre. The marine structures are designed to withstand high seismic loads and to be stable against the severe wave conditions in the Black Sea.

Cooperation with Russian experts

The Russian Ministry of Transport contracted the Lenmorniiproekt engineering firm of Saint Petersburg to provide the preparatory services in cooperation with Witteveen+Bos. Lenmorniiproekt is specialised in port design and transportation and has a designing history that goes back to 1885. The firm has vast experience in designing Russian ports. The cooperation with Lenmorniiproekt joins the Russian knowledge on ports with the latest international ports and marine structure experience from Witteveen+Bos. Close cooperation with Russian experts is essential in these mega projects to obtain approval from Russian State entities. Both companies work closely together to align designs with Russian building codes to facilitate this approval procedure.

Witteveen+Bos’ added value

Witteveen+Bos’ main responsibility is the development of port master plans and the design of the marine structures (quay walls and breakwaters). The port layout was optimised through detailed wave and flow modelling.

The marine structures are subject to large seismic loads. Detailed PLAXIS analysis resulted in fit-for-purpose design solutions, which can resist earthquakes.

In the absence of high quality rock material in close range, the breakwaters have a single layer concrete interlocking armour layer. Single layer interlocking armour units are slender units with high stability performance. Therefore, these units are selected as a cost attractive armour protection.

Design verification

The breakwater endings (roundheads) are subject to complex 3D wave loads, with a significant influence of a wide and deep access channel. Witteveen+Bos has invited Deltares, an independent research institute, to perform scale laboratory tests to verify the stability of the breakwaters with respect to armour layer stability and wave overtopping over the crest of the structure.
