Wärtsilä Technology Group has announced a collaboration with Chevron Shipping Company LLC to convert six LNG carrier engines of Chevron Transport Corporation Ltd. from dual-fuel to combustion gas . This project, which represents a breakthrough in the marine industry, is aimed at decreasing the greenhouse gas emissions by reducing methane emissions by reducing the release of methane, a potent greenhouse gas.
The engine conversion will enable a significant reduction in the carbon intensity of Chevron’s marine operations. Chevron’s marine operations. After two years of joint development, Wärtsilä has received the order for the first two vessels, scheduled for the third quarter of 2024. This innovation marks a step forward in global efforts for cleaner shipping.
SG Ship Engines: Solution to methane leakage
LNG, when used as a fuel, can release small amounts of unburned methane into the atmosphere. This phenomenon, known as “methane leakage,” is a major environmental challenge. Although methane has a shorter lifetime in the atmosphere compared to CO₂, its ability to trap heat is 25 to 30 times greater over a 100-year period, making it a key target in reducing emissions.
Wärtsilä’s engine conversion project involves the conversion of existing engines to run on combustion gas (SG), using spark ignition instead of diesel fuel. (SG), using spark ignition instead of diesel fuel. This upgrade enables more efficient combustion and reduces methane exhaust. Chevron Shipping president Barbara Pickering says this initiative is critical to achieving a less carbon-intensive future in shipping..
Wärtsilä drives maritime decarbonization
Roger Holm, president of Wärtsilä Marine, highlighted the company’s track record in implementing sustainable technologies in the maritime industry. Wärtsilä’s Wärtsilä s expertise in LNG technology, spanning nearly three decades, is reflected in the efficiency of both dual-fuel and single-fuel SG engines. This project complements its broad portfolio of solutions designed to reduce methane emissions in the shipping sector.
Thus, this collaboration between Wärtsilä and Chevron represents a significant step forward in the transition to cleaner and more sustainable maritime operations, focusing on innovative and efficient technologies for global decarbonization.
