GE Marine Solution announced that it will provide Maersk Line with its new power Take Off/Power Take In (PTO/PTI) Technology which increases fuel efficiency and operational flexibility. It is a smart solution that provides excess power on demand while reducing fuel consumption. When not being used to propel the vessel, the PTO/PTI technology uses the surplus energy to power onboard systems and equipment.
The PTO/PTI solution provided to Maersk Line for 11, 2nd generation Triple-E container vessels with a capacity of 19,630 TEU, is comprised of a shaft generator motor installed between the main engine and the propeller. It acts as either a generator or a booster to generate electricity from slow streaming speeds all the way up to the design speed of the vessel. The PTO/PTI technology will be installed onboard vessels built by the DSME shipyard in Korea, with which GE has had a long-standing relationship.
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. GE claims that the result in fuel savings is significant, especially when coupled with improved operational flexibility.
GE adds that the electric machine is equipped with induction motors instead of synchronous motors. By removing transformers, it offers a simpler design and therefore reduces the complexity of the system, making it more reliable and requiring less CAPEX
