The impact of shipping on climate change recognized as the emissions of CO2, NOx and SOx. CO2 is the major gas that may result in global warming, while NOx and SOx may cause acid rain. U-Ming manages the emissions via the guidelines of Energy Efficiency Design Index (EEOI) and Ship Energy Efficiency Management Plan (SEEMP) which requires new ships to become more energy efficient and thus, more environmental friendly.
CO2 emission control
According to the journal released by the Chinese Maritime Research Institute, CO2 accounts for about 96% of the maritime GHG emission. Therefore, the management of CO2 emission is addressed significantly in our approach.
- Fuel eciency: prepared fuel and lubricating oil consumption monthly report for EEOI; nd out the reasons if low eciency.
- Optimal shipping route: announce the meteorological chart every day; remind the sailing ships to avoid the dangerous areas from the shore.
- Optimal status of the ship's machines: perform ship maintenance periodically.
- Energy eciency: adjust the forward/backward draft of the ship within 1m when sailing; reduce water resistance.
- Slow steaming: install energy-saving and carbon-reduction facilities; adopt eco-friendly sailing speed.
NOx emission control
IMO deals with restricting the amount of NOx emission from ships' main propulsion system. There are three phases. The NOx emission should be reduced by about 20% for tier I~ tier II. In the Tier III, NOxemission standards should be 80% less than NOx Tier I. Currently, 70.27% of U-Ming's diesel engines on ships meet IMO phase-II NOx emission limits (see below chart and table for more details).,
SOx emission control
Emissions of Sulphur Oxides (SOx) are regulated through a global limit for the Sulphur content of bunker fuels to 0.5% in 2020 as well as a stricter limit in the Emission Control Area (ECA). Low Sulphur fuel and scrubbers are concerned by shipowners in order to meet the requirements. U-Ming control the SOx emissions from the change of heavy oil to the low-sulphur fuel oil (less than 0.1% sulfur which certified by the Veritas Petroleum Services (VPS)) for the ships one hour before entering ECA.
We also corporate with manufacturers to jointly develop LNG fueled Newcastlemax ships, so as to make sea shipping a model of environmental protection.
