Compared to a conventional VLCC with the same operational range and operating in the ordinary spot market, the Triality concept VLCC will:
emit 34 percent less CO2
eliminate entirely the need for ballast water
eliminate entirely the venting of cargo vapors (VOCs)
use 25 percent less energy
NOx emissions will be reduced by more than 80 percent while emissions of SOx and particulate matter will fall by as much as 95 percent.
