Collaboration to Convert LNG Carriers for Reduced Methane Emissions

Wärtsilä, in collaboration with Chevron Shipping Company LLC, is set to convert one engine on six LNG carriers operated by Chevron Transport Corporation Ltd from dual-fuel to spark gas operation. This initiative aims to reduce greenhouse gas emissions by minimizing methane slip, aligning with Chevron Shipping’s efforts to lower the carbon intensity of its operations. The project, a first in the marine industry, follows two years of partnership between the companies and the booking of the first two vessel conversions in the third quarter of 2024.

When LNG is used as a fuel, incomplete combustion can lead to methane slip, a potent greenhouse gas with significant heat-trapping capabilities. Addressing methane emissions is crucial in reducing carbon intensity, and Wärtsilä’s DF to SG conversion project is designed to tackle this issue. By modifying engines to operate on spark ignition instead of diesel pilot fuel, the conversion process optimizes combustion, reduces methane slip, and enhances efficiency.

Barbara Pickering, president of Chevron Shipping, expressed the company’s commitment to lowering methane emissions intensity in their LNG fleet for a more sustainable future. Roger Holm, President of Wärtsilä Marine, commended the innovative project as a significant step towards advancing lower carbon fleets. Wärtsilä’s extensive experience in LNG technology allows them to provide market-leading solutions for reducing methane emissions from vessels, both through newbuild options and retrofitting existing installations.

In conclusion, Wärtsilä and Chevron Shipping’s collaboration marks a milestone in the maritime industry’s efforts to reduce emissions and improve environmental sustainability. The conversion project not only addresses methane slip but also showcases the companies’ commitment to advancing lower carbon fleets. With Wärtsilä’s expertise in LNG technology and innovative solutions, the initiative sets a positive example for the industry’s transition towards cleaner and more efficient operations.
