MAY 9, 2016 — Nine  second generation Triple-E container vessels with a capacity of 19,630 TEU each being built at Daewoo Shipbuilding and Marine Engineering in Korea will have GE Marine Solutions (NYSE: GE)  Power Take Off/Power Take In (PTO/PTI) shaft generator systems.

Installed between the engine and propeller GE’s Power Take Off/Power Take In (PTO/PTI) technology consists of two drives, two induction motors and a power management system.

The PTO/PTI technology harnesses the mechanical energy of the vessel’s drive shaft to convert it into electrical energy. This excess energy is then directed to onboard systems when it is required, which diminishes the need to burn fuel to power these systems. The result in fuel savings is significant, especially when coupled with improved operational flexibility.

Unlike its competitors, the GE solution uses induction motors rather than synchronous motors. By removing transformers, says GE, it offers a simpler design and therefore reduces the complexity of the system, making it more reliable and requiring less CAPEX. The arrangement of induction motors reduces the frequency and extent of maintenance, and combined with the system’s fuel saving characteristics, bringing down the operational expenses for customers.

The Maersk order marks GE’s Marine Solutions’ entry into the container shipping industry.

Tim Schweikert, president & CEO, GE’s Marine Solutions said: “Based on our long legacy of engineering expertise and innovation, GE’s Marine Solutions continues to offer world-class capabilities in solutions that serve a wide range of marine segments. Having Maersk as a partner, our entry into the containership industry could not be more impactful. GE is continuously investing and developing solutions for the marine industry, and with our PTO/PTI technology, we are reinforcing our intention of driving the industry forward.”
