Triality - Presstogo

6 triAlity vlcc
The green VLCC
each step in the evolution
from a conventional vlcc to
triality has an impact on energy
consumption and/or emissions
to air and discharges to sea. the
energy demand is reduced for
most of the steps, giving a total
25% reduction in yearly energy
consumption.

the nox reduction given above is gained without adding any treatment
system. by adding a simple exhaust gas recirculation system for the main
engines a further reduction of at least 82% can be gained, fulfilling tier iii
emission requirements for ships built after 2016.
co2 emissions from triality compared with other transport alternatives,
based on imo figures published in 2008:
triality 3 g/tonkm
heavy truck with trailer 50 g/tonkm
Air freight 540 g/tonkm
cargo vessel >8 000 dwt 15 g/tonkm
