Siemens has received orders 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-à-Velha as well as the Railway signalling of the Nacala–Moatize mining line in Mozambique. Siemens will install the medium and low-voltage switchgear, including the motor control centres, in prefabricated power distribution units known as e-houses as well as supply the transformers and a high voltage substation. The Nacala-Moatize railway signalling order will include the installation of Positive Train Control, Interlockings and a state-of-the-art Operations Control Centre.
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. The joint venture signed a contract with the government of Mozambique to construct a railway line and a deepwater seaport as part of the Nacala corridor, which runs from the coast of Mozambique across the country, through Malawi, and back into Mozambique’s mountains. The 912-kilometre 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--à-Velha are expected to have a capacity of 18 megatons per year.
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 centres for power supply and to control the conveyor belt drives. The turnkey design supply and construction of the primary high voltage 110/22 kV substation comprises of the supply and installation of two 40 MVA and one 10 MVA Siemens transformers, a 110 kV incoming line bay with two transformer bays and a 110 kV bus section.
A key component of the seaport project is the e-Houses solution. A major advantage of e-Houses is that they can be transported to the installation site fully assembled and pretested. It takes far less time to construct and deliver an e-house solution than it does to build a separate building for the power distribution equipment, offering significant savings for the operator.
The Nacala-Moatize railway line interconnects the coal mines at Moatize with the Nacala-à-Velha Port. The railway signalling order signifies a milestone achievement in the history of the company as the recent integration of Invensys into the Siemens Rail Automation Business Unit has boosted the Siemens solution offering and overall competiveness in the railway signalling industry. Siemens successfully acquired Invensys; a UK based Rail Company in May 2013 and is now fully integrated into the Siemens business portfolio.
