UECC’s first battery-hybrid LNG-fulled PCTCs was nominated for the Motorship Award 2021! It is noteworthy to know that WE Tech offers the Hybrid Battery Solution for these vessels to significantly reducing emissions, lowering fuel consumption and deducing capital and operating expenditure.
UECC’s series of three 3600 CEU PCTCs with Hybrid Battery Solution and dual-fuel LNG engines are built according to some of the most innovative and the latest energy efficiency criteria. The Hybrid Battery Solution WE Tech delivered includes the WE Drives™, the Direct Drive Permanent Magnet Shaft Generators, DC-link power distribution, Energy Storage System (ESS) and Energy Management System (EMS).

In Power Take Out (PTO) mode, the vessel’s electrical power distribution is supplied from the shaft generator. Together with the WE Drive™ the power from the shaft generator will keep stable frequency and voltage independent of Main Engine revolutions. This allows the propulsion system to always operate in the most efficient way.
The battery package (ESS) is connected via converters to the DC-link and the WE Tech EMS gives full control of the energy flow. The ESS provides both Main Engine and auxiliary generators peak shaving, increasing the energy efficiency of the vessels. An energy reserve can be used for blackout prevention so that the auxiliary generators can be stopped without causing any blackout risk. During maneuvering or while in port, the vessels can utilize the power stored in the battery which reduces emissions in the harbor. The EMS acts as a supervisory, controlling system for the overall production and consumption of energy onboard the vessels, ensuring flexibility and optimal operations at sea, in port and during manoeuvring.
The solution will place UECC beyond IMO’s target for a 40 percent reduction in carbon intensity by 2030. They will sail predominately in the UECC Atlantic trade and will meet the Tier 3 IMO NOx emission limitations coming into force for the Baltic and the North Sea for newbuildings with keel laid on or after 1 January 2021.
