Konecranes has won a contract with South Carolina Ports to supply 12 retrofittable Hybrid Powerpacks from Rubber Tire Gantry (RTG), a milestone agreement for new technologies that enable significant reductions in CO2 emissions and lower operating costs – without compromising on performance .

The U.S. Environmental Protection Agency (EPA) approved Konecranes’ new hybrid technology in April 2021, following a comprehensive test protocol conducted by West Virginia University (WVU) at the Wando Welch Terminal on South Carolina Ports. Konecranes has teamed up with WVU to test and measure RTG exhaust emissions with the new hybrid gensets, with WVU concluding: “Carbon monoxide emissions have been over 95 compared to traditional Stage 3 diesel-electric RTG cranes % reduced. “*

The approval means South Carolina Ports and other US ports are confident of the effectiveness and sustainability of Konecranes’ technology in moving to more sustainable equipment. Funding for this retrofit is provided in part by a 2019 DERA grant awarded to the South Carolina Department of Health and Environmental Control in association with South Carolina Ports.

Refurbishment of 12 20 year old Konecranes Diesel RTG cranes based in Charleston will begin in January 2022. The contract adds to Konecranes’s momentum in the region with over 30 new hybrid RTGs being delivered to ports across America since 2020 .

“South Carolina Ports’s decision to choose Konecranes’s new technology is an indicator of the future in an industry where the focus is increasingly on finding sustainable ways to stay ahead of growing demand . We have worked with South Carolina Ports for over 24 years and look forward to building that relationship as we optimize their RTG fleet, ”said Scott Lane, VP of Konecranes US Port Services.

“Anyone can add a battery to an engine and call it ‘hybrid’, but because we make our own propulsion and control systems, we’re the only company that can turnkey upgrades completely without affecting crane performance. This agreement shows the global strength of Konecranes, which includes engineers in the US and Finland, including our RTG pioneer Jorma Merimaa, and the results have been sensational, ”added Lane.

“Working with Konecranes and with the support of our grants, SC Ports will upgrade 12 RTG cranes with hybrid battery / generator motor systems to make them both powerful and energy efficient,” said Barbara Melvin, SC Ports chief operating officer. “Konecranes technology fits in well with our efforts to invest in equipment that will both improve terminal operations and provide environmental benefits.”

The Hybrid Power Pack retrofit is part of Konecranes’ Ecolifting ™ product range, which has been designed from the ground up to deliver drastically reduced CO2 emissions. Ecolifting ™, in turn, is part of the company’s overall vision of a low-carbon, sustainable future.

A strong customer focus and commitment to business growth and continuous improvement make Konecranes an industry leader in lifting technology. This is underpinned by investments in digitization and technology as well as our work to make the material flow more efficient with solutions that decarbonise the economy and promote circular economy and safety.
