Because of the hybrid power source, it allows the usage of generators two-thirds the size of a conventional dredge vessel, further reducing CO2 emissions by 30% less than the highest tier rated generator available.
The two QSK60 generators manufactured by Cummins uses a proven Selective Catalytic Reduction (SCT) technology with a flow-through exhaust after-treatment system, using diesel exhaust fluid (DEF), to deliver ultra-low emissions.
The four banks of 20 battery modules each, are controlled by state-of-the-art software. It optimizes charge and discharge cycles by harnessing regenerative power from normal digging operations and re-charging the batteries, further reducing fuel consumption and greenhouse gas emissions.
The hybrid system designed and built by Sumimoto Heavy Industries received the Infrastructure Technology Development Award for its breakthrough innovation in increasing performance, while drastically reducing carbon footprint in the Asian market.
