Reducing CO2: Cargo Heating
 Optimized boiler operation based on projected heat loss and cargo
temperatures
 Average daily fuel consumption for cargo heating reduced from 8
MT to 5.5 MT per day

Complying with NOx regulations
 NOx regulations for new vessels:
 Tier 1 (today for post-2000 vsls)
 Tier 2 (2011) – 15% reduction from
Tier 1
 Tier 3 (2016) – 80% reduction from tier
1 in ECAs
 New Amundsen Class Shuttle
Tankers have DNV Clean Design
notation, and meet IMO Tier 2 NOx
limits in advance of the 2011
requirement
