Siemens delivers fuell cell AIP propulsion for Italian Navy’s two 212A type submarines

The Siemens Industry Solutions Division has received an order from Fincantieri Cantieri Navali Italiani S.p.A., Genova, to equip for the Italian navy two new submarines of the 212 A type with the latest drive, automation and power engineering. Already in summer 2009, Howaldtswerke-Deutsche Werft GmbH (HDW) contracted Siemens to provide the submarines with fuel-cell modules for air-independent propulsion. The current order volume is in the double-digit million-euro range.

U212A type submarine of the Italian navy equipped with fuel cell technology from Siemens near Taranto, Italy.

The order for Siemens from the Italian navy includes the supply of a Permasyn motor (permanently excited synchronous propulsion motor) for each boat, switchgear and the marine automation system EMCS (Engineering, Monitoring and Control System). The solutions and systems being used are part of the Sinavy SUB family of products developed for submarines and comply with the high requirements of submarine specifications.

The Permasyn motor was especially designed to propel submarines. The motor is extremely compact and lightweight, and because a converter is integrated inside the motor, it is highly efficient. Thanks to its special design, the Permasyn motor offers much higher performance and is quieter than DC motors available up until now, and it produces only small amounts of electromagnetic radiation. The integrated automation system EMCS controls, monitors and coordinates the vessel’s engineering systems. Operator control and visualization are carried out centrally from the control console. As a result, the operator is relieved from having to perform routine tasks, operation of the submarines is made easier, and safety and reliability are increased. The scope of supply also includes submarine-specific DC voltage switchgear, technical service and electronic documentation.
