Math Problem Statement
Calculate CII for the
Refrigerated Cargo Ship based on the following data:
• Gross Tonnage (GT): 5100
• Annual Distance Travelled (NM):
8059.1
• Annual high Sulphur Fuel Oil
(HFO) consumed during travelling: 397.4 mt
• HSFO consumption during port
stay: 0
·Annual
Marine Diesel Oil (MDO) consumed with refrigeration power 326.7 kw in port for
7945.2 hours: 815.387 mt.
·Annual Marine
Diesel Oil (MDO) total Consumed when the reefer compressors are running with refrigeration
power 905.6 kw during travelling for 403.9 hours: 151.85 mt.
• Annual Marine Diesel Oil (MDO)
total Consumed when the reefer compressors are not
running with AE power 340.3 kw
during travelling for 410.9 hours: 151.85 mt.
• Annual Total Cargo Carried:
16376.173 MT
• Main propulsion power: 3430 kW
for 928.5 hours
·Use the CO₂
emission factors for HFO: 3.114 t CO2/t. MDO: 3.206 t CO2/t
·FCelectricalreefer.j
= Reefer kWh x SFOC.
·Apply the
cargo carried in the computation of CII
