Siemens delivers technology for Italian submarines

The Siemens Industry Solutions Division has received an order from Fincantieri Cantieri Navali Italiani S.p.A., Genova, to equip two new submarines for the Italian navy with the latest drive, automation and power engineering. Siemens will also provide the submarines with fuel-cell modules for air-independent propulsion under a contract placed last year by Howaldtswerke-Deutsche Werft GmbH (HDW).

The submarines are of U212 A Type and are the second pair being built under an arrangement with the German Submarine Consortium. Construction of the first of the two started in December last year.

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 meet 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, is highly efficient. Siemens says 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.

Construction of the two submarines is the continuation of a program which started in 1994 in cooperation with the German Submarine Consortium, which led to two submarines being built for Italy -- the "Todaro" and the "Scire" delivered by Fincantieri in 2006 and 2007 respectively -- and four submarines for Germany.

At an overall length of 56 meters, the vessels will have a surface displacement of 1,450 tons and a maximum diameter of 7 m and, according to Fincantieri, will be able to reach a submerged speed of 20 knots with a crew of 24.
