he global shipping industry is undergoing a transformation. Over a


relatively short time, the issue of climate change and the potential damage from greenhouse gas emissions has risen to the top of the environmental agenda. And, whilst shipping is by far the most environmentally favourable means of cargo transport and still carries around 95% of the world’s trade, the sheer scale of the industry has forced it into a glare of publicity, not always favourable. Very soon, the IMO’s Energy

Efficiency Design Index will be adopted – a move that will mean future ship designs must improve upon existing ones, in terms of energy efficiency per unit of cargo. This is a vital catalyst in the development of new technologies in the fields of naval architecture, propulsion, emissions


management and ship operation. As usual in shipping, there are leaders and laggards. Those in the vanguard of environmental developments are enthusiastically engaged in pioneering new initiatives, intent on staying well ahead of the game. They are making sure that shipping’s environmental juggernaut gathers pace as its customers carefully scrutinise their carriers’ sustainability strategies. There are also owners and operators for whom shipping’s “greening” process is a merely


nuisance. But they adopt policies of minimum compliance at their peril. The industry is already heading towards a number of key dates which are likely to change the business for ever.


In what many believe will be a key watershed in shipping’s continuing evolution, new fuel regulations in Emission Control Areas will slash the sulphur content in ships’ fuel from January 2015 and radically alter the operating economics of countless shipping companies. At about the same time, and much sooner than many people think, ballast water treatment systems will be required on all ships of more than 400 gross tons. It is against this backdrop that shipping’s researchers and developers, its designers and suppliers are pioneering green initiatives that are yielding broad benefits in the efficiency of sea transportation. Ships that have been built in the same way for decades are being fundamentally re-analysed. Hull lines are changing, propulsion systems are being redesigned, new fuels are being considered and ship speeds are being reduced.


There is no SMM event this


year, but the publishers believe that shipping’s green developments must continue to be carefully tracked. With so many initiatives under way, this is a formidable challenge but we will continue to monitor progress in the months ahead and look forward to meeting again at SMM next year. 
