E-houses for seaport in Mozambique

Siemens has received an order from the CLN (Corredor Logistico Integrado Nacala) joint venture for the delivery, installation, and commissioning of power distribution solutions for a new deepwater seaport in Nacala-a-Velha, Mozambique.

Apart from the high voltage components and as part of the scope of work Siemens will install the medium- and low-voltage switchgear, including the motor control centers, in prefabricated power distribution units known as e-houses, which will be delivered to Africa as turnkey projects. The seaport is scheduled to begin operation in early 2015. The order volume for Siemens is valued at €56 million.

To supply power to the entire seaport facility, Siemens will deliver the transformers and medium- and low-voltage switchgear as well as suitable motor control centers for supplying power and controlling the conveyor belt motor drives. Siemens will install the equipment in five e-houses, which will be shipped from Germany to Mozambique. A major advantage of the e-house solution is that it can be transported to the installation site fully assembled and pretested. Larger units can also be transported in individual modules. This reduces the amount of time and resources required by the customer compared to constructing their own building for power distribution. Due to the high degree of prefabrication, the e-houses can be assembled and placed into operation within a short period of time. This offers measurable benefits for the operator, since every day saved during the manufacture of a unit results in an additional day of production. In addition, e-houses could be transported to a new location and reused, for example when a mine closes.

There is increasing demand worldwide from the oil & gas industry and the metals & mining sector for e-houses that are equipped with a customized power distribution equipment. Many of the existing units in these industries are built and operated in inhospitable, remote regions. Through the use of space-saving, gas-insulated switchgear, a segment in which Siemens is one of the world's leading suppliers, the company can implement particularly compact e-houses.

The CLN joint venture was formed by Vale, Brazil's largest mining company, and Caminhos de Ferro de Moçambique (CFM), Mozambique's state-run railway company. The joint venture signed a contract with the government of Mozambique to construct a railway line and a deepwater seaport. Both infrastructure projects are part of the Nacala corridor, which runs from the coast of Mozambique across the country, through Malawi, and back into Mozambique's mountains, all the way to Moatize. The 912-kilometer railway route will be used in the future to transport coal from a mine in Tete Province to the coastal shipping facilities. Once they are completed, these facilities in Nacala-a-Velha are expected to have a capacity of 18 megatons per year.

Siemens is to equip also the railway route. Siemens Mobility and Logistics Division supply signaling and control systems. This will enhance safety, capacity, and reliability of coal transportation. It will also enable more frequent trains. The automated system calculates the optimum speed and headway between trains based on the line data. This enables the railway operators to increase their network capacities by minimizing headway, improve the punctuality of their trains, and ensure energy-efficient operation. The order volume for Siemens Mobility and Logistics Division systems is valued at €70 million.
