ABSTRACT
Dakar Port, located in Senegal, is the second largest port in Western Africa behind Abidjan. It serves as a transit port to inland countries for 14% of its capacity. The 3rd wharf constructed in 1939 was reserved for the Republic of Mali under a bilateral agreement. However, the transit volume of goods had increased 2.5 times from 2010 to 2015 and is expected to continue to increase. The increase in the volume of seaborne goods has caused considerable deterioration of the wharf, which may lead to its collapse. Moreover, large vessels are constrained by draught. This paper describes the construction methodology, named the Gyropress method, used to repair the 350m long quay of the wharf. With the Gyropress method, tubular piles are pressed and rotated with the assistance of cutting ring bits attached to the pile toe. Moreover, berthing and vessel unloading at the wharf were not interrupted during construction.
