•
Maersk Line is an enabler of global trade, connecting goods and
services to people and economies around the globe
•
Shipping affects the lives of billions of people, with 90% of the
world’s international trade travelling by sea
•
With our global presence, we create local employment and
stimulate business activity in more than 125 countries
Ocean shipping is the
most energy-efficient
way to move cargo long
distances…
But is impacting the planet
90% of all goods
transported globally are
carried by ship.
Ocean shipping generates
2% of all man-made CO2.

Decoupling growth and environmental impact
Since 2007, Maersk Line has managed to grow our business
while reducing emissions to the environment.
Changes in Global Containers Shipped and Total CO2 Produced

Industry-leading energy efficiency makes
great business sense:
 Optimize our network and vessel
operations (utilization, speed,
performance monitoring and KPI’s)
 New vessels set new standards in
energy efficiency
 Existing fleet is being retrofitted with
new/best technologies
 Partner with charter owners to improve
energy efficiency - including vessel
retrofits
 We are involved in the development of
potential alternative energy for
shipping

Vessels are increasingly fuel efficient.
This reduces fuel use, CO2 and other air emissions.
Key Initiatives:




verified by:
New vessels
Eco-Retrofitting vessels
“Smart steaming”
Network design
 Focus on energy efficiency for
sustained performance
40%
 In 2014 our air emissions dropped 8%
per container while volume grew.
New 2020 goal is a
6
60%
less CO2 per container per
km 2007 - 2014
CO2 reduction.
Vessel environmental improvements take
time and partnerships.
New vessels
Existing fleet
• Optimize vessels for intended
services
• Identify or develop technologies
• Potential energy efficiency
improvements 20-50%
• Partner with technology, software and
engine suppliers
• Work with shipyards, equipment
and fuel suppliers
• Identify the right mix for each vessel
• Work with Charter vessel owners
• Long-term view plus short-term
impact
Personnel
•Vessel crews
•Shore side teams
•Structures, metrics, idea sharing
•Voyage Efficiency Center support

Voyage Efficiency Systems help optimize
performance and arrive “just-in-time.”

Maersk Line Terminal Efficiency Project:
Port Captains at larger ports work with terminals to reduce port
stays through process improvements

Innovation is essential for sustainability
 Propeller, hull & trim
optimization
 Waste heat recovery
system
 Slow steaming and
super-slow steaming
Other Initiatives
 SOx scrubber studies
 Alternative fuel tests
 Antifouling hull paint
 New propulsion technologies
 QUEST: Low energy
chilled containers
 ISO 14001 certified
 Crew awareness and engagement  Modified bulbous bow
 Maintenance of hull and propeller  Micro bubbles
 Voyage Efficiency System (VES)
 Trim optimization
10
 Ballast water optimization
and treatment systems
New ships have higher efficiencies and
provide enormous economies of scale.

Mary Maersk leaving Algeciras Spain
21 July 2014 with 17,603 TEU
It’s not just the biggest ships – it’s having
the right ships for the service needs.
Triple E – 18,000+ TEU
50% more energy-efficient
Began delivery July 2013
17 of 20 delivered as of May 2015
WAFMAX class – 4500 TEU
For West African ports (geared)
28% less CO2 per TEU
22 vessels delivered 2011 - 2012
SAMMAX class – 7500 – 8000 TEU
For South American ports
25 - 50% less CO2 per container moved
16 new vessels in 2011 - 2012.
12
Waste Heat Recovery
System
Captures heat from the
exhaust gas and uses it
 Provides energy useful
for propulsion as well as
onboard electricity
 Consumes less fuel and
generates fewer
emissions with the same
power
An excellent choice for new
vessels.
13
Retrofitting can also be a good alternative.
 Existing ships can be upgraded, reducing emissions and fuel
costs.
 Upgrading existing ships does not add new tonnage to an
already saturated market.
 Technology testing and verification of benefits is critical.
 Interesting retrofit technologies already exist, but more radical
solutions should also be considered.
14
How is a Radical Retrofit different?
Normal approach
 1 or 2 technologies / a single vessel at a time
“Radical Retrofit”
 More holistic: looking at an entire vessel/class and
impact/cost per TEU
 Integrated design of all technologies together
 Taking learnings from new build program
15
Radical Retrofit - example
Scope: Full Class
Energy Efficiency & Environmental Technologies
1. New Bulbous Bow
2. New Propeller
3. Install Propeller Boss Cap Fin
4. Engine de-rating
5. Fuel flow meters
6. Other technologies
Capacity Boost
1. Raise Wheelhouse
2. Upgrade Lashing Bridges
3. Upgrade hatch covers
4. Scantling draft evaluation
16
Propeller optimization
Extensive on-board testing and monitoring verifies results

Modified bulbous bow improves efficiency at
today’s lower speeds.
New bow
Original bow
Lower speeds call for a different shape for optimal fuel
performance

Maersk Line has announced a major
commitment to vessel retrofits.
 $1 Billion over the next 5 years on 100 of our
owned vessels
 ML also operates nearly 300 charter vessels
 Technical upgrades will radically boost fuel
efficiency and reduce CO2 emissions
significantly.
 Contributes to our 2020 CO2 target and our
cost leadership strategy
