Owners’ initiatives Maersk sets new standard T
he world’s largest container line will be setting a new environmental standard when it commissions the 20 Triple-E class container ships on order at Daewoo Shipbuilding & Marine Engineering. With deliveries commencing in 2013, the 18,000teu vessels will produce 50% less CO2 per box than the current average on the Asia Europe trade, and 20% less than today’s largest container vessels, the Emma Maersk and her sisters. The 400mtr Triple-E class vessels, costing $190m each, feature wide-ranging innovation which will improve transport efficiency whilst having only a limited impact on dimensions. The vessels will only be four metres longer and three metres wider than the Emma Maersk, but a redesigned hull form – in a ‘U’ shape, rather than a ‘V’ – will give a 16% increase in capacity, equivalent to 2,500 containers. The ships will carry 23 containers across the deck, matching the outreach of the world’s current largest terminal gantry cranes. The Triple-E class vessels – denoting economy of scale, energy efficiency and environmentally improved – will have two ultra-long-

wners in the Far East are amongst the most
environmentally conscious in the world, and despite tumbling profits and soaring bunker bills, the pursuit of green innovation remains a key priority. Asian lines are playing the long game, sure that what they do now will guarantee key shippers remain loyal in the future. Japan’s Nippon Yusen Kaisha (NYK) is in the vanguard of green developments. Since April 2006, NYK has calculated the Energy Efficiency Operational Indicator (EEOI) for around 111,000 voyages undertaken by its 904 operating vessels. This accumulated knowledge has then been fed back to the fleet as part of NYK's drive to reduce fuel consumption.
To improve the reliability of the
EEOI further, NYK is now introducing Prime Ship-GREEN/EEOI, a system offered from April this year by ClassNK, for EEOI calculations and analyses. On May 11, the NYK fleet received ClassNK’s first certification, indicating that EEOI calculations using the new system were carried out in accordance with International Maritime Organization (IMO) guidelines.
This May NYK received the highest rating for environmental management support loans conducted by the Bank of Tokyo- Mitsubishi UFJ. Meanwhile, NYK’s Cool Earth Project, launched in April 2008 under the direct supervision of the company president, has been given a more permanent status,
with the creation of the company’s new Environmental Group. NYK, along with shipbuilder Mitsubishi Heavy Industries, is behind the revolutionary green design that uses bubbles pumped along the hull to reduce resistance. Two heavylifters so far have had permanent installations of the system using an air-blower reducing CO2 emissions by as much as 10%. Last year NYK developed an additive (Yunic 700LS) for low- sulphur diesel, to help prevent mechanical troubles in fuel-oil systems. Low-sulphur marine gas oils lack lubricity and can result in issues such as abnormal friction and operational damage to engine components, as well as fuel-supply and fuel-injection pumps, says NYK.

stroke engines giving sufficient power for a service speed of 19 knots, reflecting the reduced speeds adopted by most container lines today. Waste heat recovery systems will re-use energy from exhaust gas to provide extra power and reduce fuel consumption.
Meanwhile, additional capacity has been created by a ‘two-island’ design. The bridge and accommodation has been relocated forward, enabling containers to be stacked higher in front of the bridge, while the engine room and funnel have been moved further aft. About 1,000 extra boxed can be accommodated forward and aft of the relocated bridge and accommodation as a result.
When the order was announced, Maersk Line boss Eivind Kolding
commented: ‘One of the biggest challenges we face in the world today is how to meet
Triple E-class –20% less CO2 than Emma Maersk
continue to play a key role in the development of the global economy; but, for the health of the planet, we must continue to reduce our CO2 emissions,’ he said. Maersk expects trade on the world’s most important liner route between Asia and Europe to expand by 5-8% a year between now and 2015. Kolding also noted the increased significance placed by shippers on shipping liners’

he said, ‘and also for a growing number of consumers who base their purchasing decisions on this type of information.’
