Wärtsilä has completed a targeted engine conversion on three liquefied natural gas carriers operated by Chevron Transport Corporation in a project intended to curb vessel methane emissions.
The work involved converting one engine on each ship from a dual-fuel configuration to spark gas operation, the vessel owner and supplier reported. The conversions form a discrete element of a broader effort to address methane output from the carriers.
Conversion work completed
According to the report published on 3 November 2026 by MarineLink Maritime News, Wärtsilä carried out the conversions of a single engine on each of the three vessels. The supplier completed the changes that alter how the engines ignite and manage gas, moving away from the dual-fuel arrangement on the specified engine to a spark-ignited gas mode.
The conversions were performed while the ships remained in service under Chevron Transport Corporation's operation, with each modification applied to one engine per vessel. The completed work marks the conclusion of the described engineering scope on the three carriers.
Intended environmental outcome
The project was expressly framed as an emissions-reduction initiative, aimed at cutting methane released by the vessels. MarineLink's item characterises the conversions as part of a deliberate attempt to reduce methane emissions from the affected ships.
Wärtsilä's completion of the conversions therefore represents a technical step taken within that stated objective rather than a declaration of measured emission outcomes. The reporting describes the activity and its environmental intent without advancing quantified results in the published summary.
The three ships involved are identified only as LNG carriers operated by Chevron Transport Corporation. The report specifies the scope precisely as one engine per vessel but does not disclose further details concerning ship names or additional modifications beyond the conversion to spark gas operation.
The supplier and ship operator are the two parties named in the published account, with Wärtsilä delivering the engineering work and Chevron Transport Corporation operating the vessels that received the upgrades. MarineLink carried the item on 3 November 2026, which supplies the contemporaneous date for the announcement of the completed conversions.
The project has been presented publicly in the brief form recorded by the trade news item, which concentrated on the technical change and its connection to reducing methane emissions from the three carriers. The account sets out the conversion activity as a completed phase of work within the stated emissions-reduction programme.
The work described by MarineLink involved standard industrial partners in the gas carrier sector. The report confines its factual claims to the conversions themselves, their technical nature as a change from dual-fuel to spark gas operation on one engine per vessel, and the stated aim of lowering methane emissions from the ships operated by Chevron Transport Corporation.
The development will be of interest to operators, equipment suppliers and regulators concerned with greenhouse gas and methane management in the LNG shipping sector. The published note situates the conversions as a defined engineering response to an emissions challenge faced by the three carriers under Chevron Transport Corporation's management.
