Ship emission
Environnemental Performance (SPI)
Release substances
This KPI expresses the company’s ability to avoid releases of substances as defined by MARPOL
Ballast water management violaitions
Ability to adhere to applicable rules and regulations related to
management of ballast water.
Contained spills - PI024
Expresses the company’s ability to avoid spills.
Environnemental deficiencies
Expresses the company’s ability to avoid environmental related deficiencies.
KPI_value = PI027 / PI052
PI027 Number of environmental related deficiencies
PI052 Number of recorded external inspections
CO2 efficiency
Expresses the energy efficiency of the ship by comparing emitted mass of CO2 to the ship’s
total transport work.
KPI_value = PI007 / PI064 x 10^6
PI007 Emitted mass of CO2
PI064 Transport work
NOx efficiency
Expresses the amount of NOx emitted relative to the transport work performed.
KPI_value = PI008 / PI064 x 10^3
PI008 Emitted mass of NOx
PI064 Transport work
SOx efficiency
Expresses the energy efficiency of a ship by comparing emitted mass of SOx emitted relative to
the transport work performed.
PI009 / PI064 x 10^3
PI009 Emitted mass of SOx
PI064 Transport work
Method
Main Engine
EEDI
Exhaust gaz
AIS method
Method
Speed + Engine power gives consumption (SFOC)
Emissions Factor + consumption - Emissions
Diffierent AIS types
Class B
Same as class A, but at low powered messages are less often
Class A
Report position every 2-10seconds & every 3 mins when moored
