This is the second LNG bunkering operation that Total is setting up, see link below.

First LNG-Bunkering Vessel for a French Port Prepares for Deployment
The first liquefied natural gas bunker vessel that will be deployed in a French homeport later this year is nearing completion at a shipyard in China. Built for the collaboration between TotalEnergies Marine Fuels and Mitsui O.S.K. Lines, the vessel will be among the largest LNG bunker vessels and incorporate several refinements in the design versus the group’s first vessel that was placed into service last year.
The new vessel is being built in China at Hudong-Zhonghua Shipbuilding. TotalEnergies Marine Fuels and MOL signed a long-term charter contract in November 2019 and construction commenced in April 2020.
The vessel, which will have a capacity of 18,600-m³ was launched at the end of April 2021. In June, sea trials were conducted off Shanghai, where the new vessel’s navigation and propulsion systems were successfully tested, including speed and maneuverability assessments. Gas trials were completed in early July, with the ship management team in attendance.
The vessel is similar in size to the company’s first LNG bunker vessel, the Gas Agility, however, it benefits from the operating experience to incorporate enhanced equipment boosting its bunkering efficiency and flexibility to supply LNG to a wide range of vessels across various segments and sizes. Both vessels are 443 feet in length using LNG as propulsion fuel and integrating a complete re-liquefaction of the boil-off gas. They are GTT Mark III membrane vessels....

We noted in November 2020's "Fill 'er up: "Historic LNG Bunkering Operation Underway in Rotterdam" (CMA CGM; Total)" that these ships a very large in their own right but look like toys compared to the CMA CGM container behemoths:
From Total: Total's "Gas Agility" is the world's largest LNG bunker vessel
The Jacques Saadé is the CMA CGM (and thus France's) commercial flagship
