Some figures for reference
Total fuel oil consumption: 1 600 000 tons
Total cost of fuel: 1 000 000 000 USD
5 000 000 tons of CO2 6 500 tons of NOx 50 000 tons of SOx ?? tons of Particles
140 vessels in 3 commercial operators owned jointly with our Swedish partner Wallenius Lines

Managing a New Reality
• 3
• Sulphur Regulations• A four-stream compliance strategy
• Low Sulphur Bunker Oil
• Alternative fuels
• Exhaust Gas Cleaning Systems
• ”Scrubbers”
• MGO
4
Background; low sulphur fuel challenges
- Availability - Quality- Quantity; tank configuration and capacities- Planning of bunkering- Compliance; enforcement of ECA regulations- Safety and reliability in fuel switch and operation- Crew pressure- Overall cost

Some figures for the Tarago pilot scrubber
17 m
7 m20 m
Fuel consumption: 70 tons/day
20.000 tons/year
Price gap MGO / HFO: 350 USD (2015)
Saving potential:
100% in ECAs 7.0 MUSD /year
23% in ECAs 1.6 MUSD /year
Overall project cost 10 MUSD
Third party measurement and verification. Sponsored by the Norwegian Research Councel
Testing starts this summer

Main scrubber being lifted onboard
11
Main scrubber with the two venturies
12
New funnel top section; 45 tons
13
More scrubbers in our fleet?
Retrofits can be complex and expensive Suitable for newbuilds A competetive advantage Engineering capacity a limitation (?) Technical and financial risks manageable Political risk an issue (?)
14
But, most important of all;
….. a highly motivated crew!
