RS Director General Konstantin Palnikov took part in the ship delivery ceremony on behalf of RS. He noted that an innovative direct current power distribution system implemented onboard gives an opportunity to save fuel on fractional loads mode. The system also extends the service life of main generators driving engines as it allows selecting their optimal operation mode.
