Chevron retrofits LNG fleet to cut methane slip

Wärtsilä, in partnership with Chevron Shipping, is converting one engine on six of Chevron’s LNG carriers from dual-fuel (DF) to spark gas (SG) operation, a first-of-its-kind project in the marine industry aiming to reduce methane slip.

Wärtsilä’s 50DF to SG conversion project is designed to modify the engines in service to operate as SG, using spark ignition versus diesel pilot fuel to initiate combustion. 

“Chevron Shipping aims to reduce methane emissions intensity of our LNG fleet in support of a lower carbon future,” said Barbara Pickering, president of Chevron Shipping.”
