Hybrid crane upgrade advances emissions reduction at DP World terminal

DP World is increasing its decarbonization efforts with the introduction of a hybrid rubber-tired gantry crane at its Prince Rupert terminal. The retrofit lowers fuel consumption by more than 60% compared to a conventional diesel-powered crane and is expected to prevent approximately 100 metric tons of CO₂e emissions annually.

The upgrade converted an existing diesel-powered crane into a hybrid diesel-electric system through collaboration with ZPMC North America Inc., a port container crane manufacturer. The modification involved replacing a large diesel engine with a smaller 80 kW generator that charges onboard batteries, greatly enhancing the crane's energy efficiency.

In addition to reducing fuel use, the system incorporates energy recovery capabilities. Power that is generated while the containers are lowered is captured and reused in subsequent lifting operations, contributing to overall performance gains. Early operational data indicates that the retrofit also reduces engine wear, resulting in lower maintenance requirements and improved reliability.

Unlike fully electric cranes, the hybrid configuration operates independently of external charging infrastructure. The onboard generator provides flexibility by maintaining battery charge as needed, ensuring continuous operation without changes to terminal power systems.

The Prince Rupert terminal currently operates six rubber-tired gantry cranes, with this retrofit marking the first conversion. Additional retrofits are planned as part of a broader equipment modernization program to reduce emissions across DP World’s Canadian operations.
