Chevron Shipping, Wärtsilä Partner to Lower Methane Emissions on LNG Carriers

Technology group Wärtsilä, in partnership with Chevron Shipping Company LLC, plans to convert one engine on six of Chevron Transport Corporation Ltd.’s LNG Carriers from dual-fuel (DF) to spark gas (SG) operation. The conversions are intended to reduce greenhouse gas emissions by lowering methane slip in support of Chevron Shipping’s broader efforts to reduce the carbon intensity of its operations. This marine industry first was made possible after two years of collaboration between the companies. The order for the first two vessels was booked by Wärtsilä in Q3 2024.

LNG, when burned as a fuel, results in small amounts of methane that may not fully combust leading to methane escaping into the atmosphere, referred to as methane slip. Methane exists in the atmosphere for a shorter time than CO₂ but traps approximately 25–30* times more heat over a 100-year period. Addressing methane emissions is a key part of lowering carbon intensity. 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. This enables a more optimised combustion process, thereby reducing the methane slip and improving efficiency.

“Chevron Shipping aims to reduce methane emissions intensity of our LNG fleet in support of a lower carbon future,” says Barbara Pickering, president of Chevron Shipping. “We are pleased to collaborate with Wärtsilä in this industry first. This demonstrates steps we are taking to help reduce the carbon intensity of marine transportation."

“This innovative project represents a notable step forward on the road to advancing lower carbon fleets,” comments Roger Holm, president of Wärtsilä Marine & executive vice president at Wärtsilä Corporation. “Wärtsilä has an extensive track-record in reducing methane slip from LNG-fuelled engines, not only as newbuild solutions, but also through retrofitting existing installations.”

This new technology complements Wärtsilä's extensive portfolio of solutions aimed at reducing methane emissions from vessels. With nearly three decades of experience in LNG technology, Wärtsilä is providing market leading performance both with the dual fuel flexibility provided by the DF engine, as well as with the single fuel SG engine.

Unless legally required, Chevron undertakes no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise.

Among the important factors that could cause actual results to differ materially from those in the forward-looking statements are: changing crude oil and natural gas prices and demand for the company’s products, and production curtailments due to market conditions; crude oil production quotas or other actions that might be imposed by the Organization of Petroleum Exporting Countries and other producing countries; technological advancements; changes to government policies in the countries in which the company operates; public health crises, such as pandemics and epidemics, and any related government policies and actions; disruptions in the company’s global supply chain, including supply chain constraints and escalation of the cost of goods and services; changing economic, regulatory and political environments in the various countries in which the company operates; general domestic and international economic, market and political conditions, including the military conflict between Russia and Ukraine, the conflict in Israel and the global response to these hostilities; changing refining, marketing and chemicals margins; actions of competitors or regulators; timing of exploration expenses; timing of crude oil liftings; the competitiveness of alternate-energy sources or product substitutes; development of large carbon capture and offset markets; the results of operations and financial condition of the company’s suppliers, vendors, partners and equity affiliates; the inability or failure of the company’s joint-venture partners to fund their share of operations and development activities; the potential failure to achieve expected net production from existing and future crude oil and natural gas development projects; potential delays in the development, construction or start-up of planned projects; the potential disruption or interruption of the company’s operations due to war, accidents, political events, civil unrest, severe weather, cyber threats, terrorist acts, or other natural or human causes beyond the company’s control; the potential liability for remedial actions or assessments under existing or future environmental regulations and litigation; significant operational, investment or product changes undertaken or required by existing or future environmental statutes and regulations, including international agreements and national or regional legislation and regulatory measures related to greenhouse gas emissions and climate change; the potential liability resulting from pending or future litigation; the risk that regulatory approvals with respect to the Hess Corporation (Hess) transaction are not obtained or are obtained subject to conditions that are not anticipated by the company and Hess; potential delays in consummating the Hess transaction, including as a result of regulatory proceedings or the ongoing arbitration proceedings regarding preemptive rights in the Stabroek Block joint operating agreement; risks that such ongoing arbitration is not satisfactorily resolved and the potential transaction fails to be consummated; uncertainties as to whether the potential transaction, if consummated, will achieve its anticipated economic benefits, including as a result of regulatory proceedings and risks associated with third party contracts containing material consent, anti-assignment, transfer or other provisions that may be related to the potential transaction that are not waived or otherwise satisfactorily resolved; the company’s ability to integrate Hess’ operations in a successful manner and in the expected time period; the possibility that any of the anticipated benefits and projected synergies of the potential transaction will not be realized or will not be realized within the expected time period; the company’s future acquisitions or dispositions of assets or shares or the delay or failure of such transactions to close based on required closing conditions; the potential for gains and losses from asset dispositions or impairments; government mandated sales, divestitures, recapitalizations, taxes and tax audits, tariffs, sanctions, changes in fiscal terms or restrictions on scope of company operations; foreign currency movements compared with the U.S. dollar; higher inflation and related impacts; material reductions in corporate liquidity and access to debt markets; changes to the company’s capital allocation strategies; the effects of changed accounting rules under generally accepted accounting principles promulgated by rule-setting bodies; the company’s ability to identify and mitigate the risks and hazards inherent in operating in the global energy industry; and the factors set forth under the heading “Risk Factors” on pages 20 through 26 of the company’s 2023 Annual Report on Form 10-K and in subsequent filings with the U.S. Securities and Exchange Commission.
