LNG

Shipping subsidiaries of energy majors Chevron Corp. and TotalEnergies along with the LNG and gas cargoes carrier company Seapeak, have joined a global technology-led initiative for cleaner shipping.

The Methane Abatement in Maritime Innovation Initiative (MAMII) is led by SafetyTech Accelerator, a firm established by UK maritime classification society Lloyd’s Register.

“Our mission is to make the world safer and more sustainable through wider adoption of technology,” said SafetyTech Accelerator.

TotalEnergies and Chevron joins the group with Seapeak, which was formerly known as Teekay LNG and alone has over 90 gas carriers, including 50 LNG tankers.

The three companies join the now more than 20 members of MAMII, emphasising its pivotal role in addressing methane abatement within the maritime sector.

Contributions

Chevron, Seapeak and TotalEnergies have pledged to bring their valuable insights and commitment to the critical challenge of “methane slip”, an escape of gas that adds to pollution from dual-fuel engines or other technology.

The initiative has additionally selected four technology providers to produce feasibility studies on the technologies which will reduce methane emissions from ships.

“The release of unburnt methane is a key obstacle to unlocking the full environmental potential of LNG as a maritime fuel,” said a statement.

Now in its second year, MAMII was launched in September 2022 by Safetytech Accelerator, bringing together industry leaders, technology innovators and maritime stakeholders to mitigate methane emissions.

“Chevron Shipping is very pleased to join MAMII. We are committed to reducing methane emissions from our LNG carriers and MAMII is an excellent opportunity for us to work with industry leaders on sharing best practices and exploring new technologies,” said Lloyd Bland, a senior manager at Chevron Shipping.

Chris McDade, Vice President of Operations at Seapeak said that LNG was already the preferred choice versus traditional marine fuels.

“However, but even more can be done to minimise the environmental impact,” McDade added.

Partners

“As a MAMII anchor partner, our fleet will directly participate in feasibility studies, new equipment trials and testing of technical solutions to reduce or eliminate methane slip from LNG vessels,” he stated.

The initiative is currently focussed on “on-ship” trials, expanding the range of pilot projects and starting to address fugitive methane emissions covering the entire spectrum of emissions on LNG-fuelled vessels.

“As the world's third-largest LNG player, we are delighted to be joining the MAMII initiative and contribute our expertise in reducing the emissions all along the gas value chain,” said Jerome Cousin, Senior Vice President of Shipping at TotalEnergies.

“It is key for TotalEnergies to further improve the environmental benefits of LNG as a marine fuel, already a major decarbonization lever for the maritime industry,” Cousin added.

The full list of MAMII members: Capital Gas, Carnival Corp. Celsius Tankers, Chevron, CoolCo, JPMorgan, Knutsen Group, Lloyd’s Register, Maran Gas Maritime, Mediterranean Shipping Co., Mitsui OSK Lines, MISC, NYK Line, Seapeak, Seaspan Corp., Shell, TMS Cardiff Gas, TotalEnergies, UK P&I Club and United Overseas Management.

Hyundai Marine Solution Co., the South Korean ship services provider, has been awarded an order for re-liquefaction upgrades on some of the LNG carriers operated by the shipping unit of Chevron Corp.

Chevron Corp. has said liquefied natural gas was a key component of the energy transition on land and at sea and plans to upgrade its fleet of 10 LNG carriers at the Singapore shipyard of Sembcorp Marine Ltd.

Chevron through its subsidiary Chevron Shipping Company has signed an agreement with Sembcorp Marine Repairs & Upgrades, a unit of Sembcorp Marine, to help reduce the carbon-intensity of its LNG fleet operations.

“Under the agreement, with Sembcorp Marine’s support, Chevron will install new technologies aboard Chevron vessels to support their energy transition goals,” said a statement.

“The changes are also in alignment with decarbonization targets set by the International Maritime Organization,” Chevron added.

Chevron Shipping operates a fleet of around 30 ships from conventional crude and petroleum product carriers to LNG carriers.

In addition to providing marine transportation for the company, Chevron Shipping provides technical, commercial and operational support to projects such as the Gorgon LNG and Wheatstone LNG export plants in Western Australia.

LNG technologies

Chevron said its LNG fleet plans included installing new technologies such as a reliquefication system, hull air lubrication and new gas compressors.

The company expects that all these measure together are expected to reduce cargo boil-off, lower fuel consumption and increase volumes of cargo delivered.

“We are excited to work with Sembcorp Marine to help us advance our lower carbon goals,” said Mark Ross, President of Chevron Shipping.

“We believe LNG will be a key component of the global energy transition for years to come and Chevron is focused on continuing its disciplined capital investment in our LNG fleet,” added Ross.

Chevron stated that Sembcorp Marine had significant expertise in complex LNG fleet modifications and a proven track record for lower carbon solutions for the maritime industry.

The Singaporean company will provide Chevron with engineering, procurement, installation and commissioning services and expects to complete the work by mid-2025.

“Sembcorp Marine is committed to advancing environmental sustainability through the development of industry-leading solutions,” said Wong Weng Sun, Sembcorp Marine President and Chief Executive.

“Working with Chevron on its LNG fleet upgrades is an immediate way to accelerate the lowering of the carbon footprint in the maritime industry, to achieve the IMO’s target to reduce emissions from international shipping by at least half,” added Wong.
