Maersk Line is to install GE’s Marine Solutions Power Take Off/Power Take In (PTO/PTI) shaft generator systems to its container ships to provide excess power and increase fuel efficiency.
This movement marks GE’s Marine Solutions’ entry into the container ship industry.
The PTO/PTI solutions, which are to be installed between the engine and the propeller, harness 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, eliminating the need to burn fuel to power these systems. This results in significant fuel savings and operational flexibility.
The solution also uses induction motors rather than synchronous motors. The arrangement of the induction motors reduces the frequency and extent of maintenance, while the elimination of the transformers means that the design is both simple and easy to install with low CAPEX.
Nine of Maersk’s second generation Triple-E container vessels, each with a capacity of 19,630 TEU will feature the technology, which consists overall of two drives, two induction motors and a power management system.
The ships are to be built at Daewoo Shipbuilding and Marine Engineering in Korea.
