Our Way 1
THE ENVIRONMENTAL VISION – PAST, PRESENT & FUTURE
WALLENIUS MARINE ahead of rules FOR ALMOST 30 YEARS 2011 NOx rules allowEnvironmental sustainability has always been a key cornerstone for Wallenius Marine and other companies in the Group. We were the first in Sweden, and among the first globally, to become ISO14001 certified, as early as 1998. In many ways, Wallenius Marine and its sister companies have been front-runners for the development of a more sustainable shipping environment, having taken responsibility in eliminating harmful substances long before regulations came into force. ance: 14.4 g/kWh for two-stroke, slowmoving marine diesel engines 2006 MARPOL 73/78 Annex VI, Prevention of Air pollution from ships, came into force. It seek to minimise airborne emissions from ships (NOx, SOx) 2010 Revised Annex VI, with significantly tightened emissions limits, came into force on 1 July Legal requirements 1997 1998 1999 2000 2001 Wallenius Marine’s actions 1998 A project to find new fuel alternatives is carried out using MDO instead of HFO. Average sulphur content: 0.66% over the year 1999 Low-NOx nozzles installed on all Wallenius newbuildings Auxiliary engines and boilers onboard Wallenius vessels are running on Marine Gas Oil (MGO) or Marine Diesel Oil (MDO) with a maximum sulphur content of 0.2% 2000 NOx emissions reduced by 20–30% due to the use of sliding valves on the main engine onboard Wallenius vessels 2008 2004 World record in low sulphur content in the fuel (bunker oil) for ocean-going services. (Our Swedish flagged vessels have 1.16%) Between 1998 and 2008, Wallenius reduced NOx by 25% measured in g/kWh 2007 Wallenius reached a NOx reduction of 21% for our Swedish flagged vessels. 2011 NOx levels 13.2 g/kWh fleet-wide 2009 PMA, Performance Monitoring & Analysis, a ship reporting system with the aim to streamline vessel performance, is developed. By optimizing operations emissions are reduced 2002 2003 2004 2005 2006 2007 2008 2009 2010 20 CO2 Carbon dioxide is a naturally occurring greenhouse gas that plays a key role in plant life and helps keep the earth warm. Increasing levels of CO2 in the atmosphere contribute to global warming. NOx NOx gases react to form smog and acid rain as well as being central to the formation of fine particles and ground-level ozone, which are both associated with adverse health effects. High concentrations cause inflammation of the airways. 18 OUR WAY SHIPPING SOx Sulphur dioxide is a precursor to acid rain. When inhaled, SOx causes a number of respiratory symptoms in humans, including difficulty breathing, chronic respiratory disease and even death.
