The Port of Mombasa plays a vital role in the transport network of East Africa as it serves a region of over 250 million people and handles the traffic to Kenya, South Sudan, Uganda, Rwanda, Burundi, Democratic Republic of Congo (DRC) and Tanzania. An expansion programme was needed, since a large part of the infrastructure in the port has seen better days. Some parts needed replacement and some needed to be up-graded to larger container vessels.
The new Berth 19
NIRAS has provided services to the Port of Mombasa for the extension of a new Berth 19.
The project included an extension of the existing Berth 16-18 of 260 m. The draft of the new quay is 12.2 m. The structure is an open piled suspended structure - steel piles with a concrete deck.
The project also includes design of crane rails for Ship to Shore gantry cranes weighing 980 tonnes with a rail gauge of 27.45 m and establishment of approx. 5 hectares of adjacent container stacking areas for rubber tired transtainer gantry cranes, all paved with heavy duty pavement.
Furthermore, the project includes transfer of know-how by on-the-job training of engineers from the engineering and maintenance departments.
An integral part of the Mombasa container terminal is comprised by Berth 16–18. To prepare these berths for post panamax STS cranes, KPA as the client retained NIRAS to analyze the capacity of the berths, and to upgrade the quay structures as well as the quay aprons to cater for modern container handling.
Condition survey of the structures
A condition survey of the structures in Berth 16-18 (600 m long open structures suspended on piles) and the fendering system was conducted. The survey comprised an examination of piles (steel and concrete) and the condition of the reinforced concrete deck.
Based on the results from the survey, alternatives for rehabilitation of deteriorated/damaged structures were prepared. The project included a training component for engineers from the maintenance section of the port. The engineers were trained in maintenance of marine structures, basic concrete technology, corrosion protection, etc., in addition to on-the-job training, while the rehabilitation programme was carried out on site.
Project cost: USD 45,000,000
