Emissions Technology 

Prepared for the future 

Long term emissions perspective 

At MAN Diesel & Turbo, our policy is to guarantee the 

maritime industry a secure basis for the future. 

In terms of engine emissions we provide our customers 

with engines that will meet the emissions limits 

prescribed in the International Maritime Organisation’s 

IMO MARPOL 73/78 Annex VI. 

Currently this means complying with IMO Tier II and 

IMO Tier III, the second and third stages of regulations 

governing emissions of oxides of nitrogen (NO x ). 

Full ahead from IMO Tier II to Tier III 

With this security of supply in mind, MAN Diesel & Turbo 

announced its full range of IMO Tier II compliant low 

and medium speed diesels in 2008 – a full shipbuilding 

cycle ahead of IMO Tier II’s 2011 introduction. 

Now, to give the shipping industry clear, long term 

perspectives, MAN Diesel & Turbo is offering solutions 

for compliance with IMO Tier III, even further ahead of 

its 2016 implementation date. 

ECAs 

Driving this early response is the prospect of individual 

countries and regions nominating so-called Emission 

Control Areas (ECAs) in advance of the IMO Tier III 

starting date. 

Significantly, IMO Tier III retains the same limits for 

emissions of oxides of nitrogen (NO x ) as IMO Tier II for 

vessels on the high seas. 

However, it prescribes far stricter limits in waters close 

to centres of population like landlocked seas, restricted 

sea lanes and straits, harbour approaches and 

coastal waters near environmentally sensitive areas. 

Incentives 

In addition to the early designation of ECAs, a number 

of National Governments are now offering incentives 

to ships operating at reduced NO x emissions in their 

territorial waters. 

4 Offshore – Exploration, Production, Supply

SCR - Selective Catalytic Reduction of NO x 

These developments have created immediate demand 

for engines with NO x emissions in the IMO Tier III range, 

well before 2016. 

World map ECA 

Crucially, emissions upgrades are also offered for vessels 

already in service, as owners seek NO x compliance 

in ECAs and qualification for incentives. 

Core technologies in-house 

As well as its expertise in engine design, development 

and manufacture MAN Diesel & Turbo is also a leading 

manufacturer of the key technologies which determine 

the economic and ecological performance of a 

diesel engine. The core technologies are: 

• 

Turbochargers 

• 

Fuel injection equipment 

• 

Engine control and safety systems
