Reliable Marine Propulsion ABB - the World´s Leading Supplier of Electric P Reliability is crucial for all operations at sea, and innovative technological solutions must be based on extensive experience. The highly advanced solutions that ABB offers today are the result of over half a century of experience in the maritime industry. Our Solutions Become Standards To maintain our technological leadership in the marine industry, which is one of ABB’s core industries, we invest substantial resources in developing technology de- signed to raise quality and profitability for our customers. It is therefore only logical that we were the company to introduce Azipod®, the first azimuthing podded propulsion system, to the maritime industry. Leading-edge Drive Technology ABB is the world’s largest producer of electric motors and drive systems. Research into AC drives technology started in the 1960s and industrial production started in the 1970s. This pioneering spirit has made ABB the world`s leading supplier of AC drives. Our unrivalled experience in AC drives technology, combined with our long experience in the marine industry, results in innovative drive solutions designed for marine duty. We supply complete solutions for all kinds of applications – from the smallest pump and fan drive to comprehensive electric propulsion and power plants with integrated automation systems. 2 c Propulsion Systems With ABB, you can experience the future today. 3 Extensive References Our success is best documented through Research and Survey vessels our extensive list of references covering Icebreakers all kinds of ships and floating structures.

As a result, control of the drive low losses of the IGCT require less cooling capacity and is immediate and smooth under all conditions. smaller cooling equipment. With DTC, speed and position encoders can be eliminated, The fast switching enables the implementation of novel thereby reducing the maintenance costs and ensuring high control algorithms. The converter design with IGCT allows availability. Fast DTC control also guarantees minimum torque the use of a fuseless main circuitry. This increases the ripple and results in minimum machine wear. The high availability of the drive since the protective functions are switching frequency also reduces the noise considerably. actively controlled by the converter control, and recovery from a fault can be accelerated.
