Energy Observer docks at Khanh Hoi Port in HCMC's District 4 on Wednesday as part of its visit to the city from June 18 to 29.
The French vessel has been on a world tour for five years without having to consume any fossil fuel. It is the first vessel in the world that is autonomous in energy thanks to her onboard technologies, combining multiple sources of solar, wind and hydropower produced on board.
Following her launch in April 2017, Energy Observer departed on a world tour that year, with HCMC its 73rd stop.
Departing from its home port of Saint-Malo (France) in 2017, the Energy Observer has sailed more than 50,000 nautical miles and visited more than 40 countries and territories.
