Hanwha Ocean announced that it has developed a smart ship technology that monitors a vessel’s carbon intensity index (CII).
According to Hanwha Ocean, the new technology assesses how much carbon dioxide a ship produces while it is operating and uses this information to calculate its annual operational CII — a measure of fuel efficiency based on fuel usage and distance traveled. Hanwha Ocean will deploy this technology in recently contracted orders for very large ammonia carriers (VLAC), improving the carbon footprint of these vessels.
Do you know what CII stands for?
Applying to all cargo, RoPax, and cruise ships above 5,000 GT, the CII is an operational index based on the Annual Efficiency Ratio (AER). This ratio is given in grams of CO2 emitted per cargo-carrying capacity and nautical mile, measuring all carbon emissions from all ballast and laden voyages, anchorage, and port stays, all divided by the deadweight and distance sailed in a year.
In simple terms, the Carbon Intensity Indicator (CII) is a measure of how efficiently a ship transports its cargo. Based on this, the ship is then given an annual rating ranging from A to E:
A – major superior performance level
B – minor superior performance level
C – moderate performance level
D – minor inferior performance level
E – inferior performance level
Hanwha Ocean also noted that shipowners can see important data in real time so they can optimize navigation routes and speed to reduce carbon dioxide emissions.
