Emissions to air

Fuel

 

WW’s overall goal is to reduce the amount of fuel consumed by its fleet. Several initiatives are being pursed to reduce fuel consumption and emissions.

 

In 2009, WW’s goal was to reduce the fuel consumption measured in g/tonnes/nm by 4% compared to 2008. The total fuel consumption went down by 20%. However, as a consequence of less cargo to transport, consumption went up by 25%.

 

The fuel-saving initiatives included:
choosing optimal speed whenever possibleenvironmental awareness training for our offices and vessel managersenergy management systems that help the crew to identify optimum sailing conditions installing weather routing systems on board all our vessels to ensure efficient route planning and safe sailingan extensive newbuilding programme with fuel efficient vessels (new design with improved propulsion systems)installing homogenisers for more efficient utilisation of the fuel by improving combustion and reducing the amount of sludge extracted from the fuel

 

 

Carbon dioxide

 

WW aims at reducing its carbon footprint by focusing on reduction in fuel consumption. WW is also
involved in developing new carbon indexes for the industry.

 

In 2009, WW’s goal was to reduce CO2 emissions measured in g/tonnes/nm by 4% from 2008 level in line with the reduction in bunkers consumption. The total CO2 emissions went down 20%.Due to the global economic recession, less cargo was transported and the g/tonnes/nm emissions went up with 25%. No regulations currently govern CO2 emissions from shipping.

 

However, WW is engaged in work being pursued by the International Maritime Organisation (IMO) to create an Energy Efficiency Design Index (EEDI) and an Energy Efficiency Operational Indicator (EEOI). WW is also comparing its environmental management system with IMO’s Ship Energy Efficiency Management Plan (SEEMP). The three projects aim at having more efficient vessels in the future.

 

Sulphur oxides

 

Vessels operated by WW’s operating companies hold sulphur content policies below international regulations.

Wallenius Wilhelmsen Logistics (WWL) was in 2005 the first worldwide merchant shipping operator with a 1.5% sulphur policy. EUKOR Car Carriers has practiced a 2.5% sulphur policy since 2007.

 

Currently, the sulphur content limit is 4.5%. From 2012, the IMO has set a 3.5% limit for sulphur content worldwide. In addition two Sulphur Emission Control Areas (SECAs) have been established covering northern Europe and the Baltic region, where bunkers with a sulphur content higher than 1.5% is prohibited.

 

The number of such areas is expected to increase in the future. Using low-sulphur fuel incurred an additional cost of USD 2.7 million (WW’s share) in 2009.

 

Nitrogen oxides

 

Nitrogen oxides (NOX) WW aims at reducing NOX emissions through technical improvements and fleet renewal. In 2009, WW’s vessels reduced NOX emissions measured in g/tonnes/nm by 4% compared with 2008 and compared with 2000.

 

New vessels are designed with lower NOX emissions from its engines compared with existing tonnage.  In addition, WW has equipped some engines with more efficient fuel valves which optimise combustion and reduce NOX emissions.

 

Yarwil, a joint venture owned 50% by Wilhelmsen Maritime Services, has developed a new technology that reduces NOX emissions by 95%.WW runs a project aiming at testing the system on WW owned or controlled vessels.
