DNV says existing fleet can cut carbon footprint by 15%

08 Jun 2009

According to Det Norske Veritas, a new study shows that with minimal modifications current ships can cut their emissions to air by some 15%. Announcing the results of the study at a pre-NorShipping press conference, DNV Maritime COO Tor Svensen said the improvements can be achieved now, with present technology, mainly through better operational practices, and offer an improved bottom line for operators.

A new tool, known as DNV Triple-E, has also been developed to obtain measurable improvements for individual ships.

DNV says that ships from all market segments can reduce their air emissions. On average, optimising the engine performance, the trim for all drafts and speeds and the propulsion system efficiency and, among other measures, improving voyage management can reduce emissions by 15% for all type of ships ? all to be achieved without additional costs. Even greater reductions might be possible.

DNV has developed a set of abatement curves to plot the achievable emission reductions against the estimated cost effectiveness. These curves are a result of research activity within DNV but are based on factual and measurable improvements achieved by owners, operators and individual ships in operation.

Svensen says: "DNV has worked with clients on energy management projects for years, and gained lots of experience and factual knowledge when it comes to both emission reduction potential and cost reduction potential. This excellent cooperation with mainly owners and operators has been essential to ensure the quality and accuracy of our research results."

The DNV Triple-E (Environmental & Energy Efficiency Rating Scheme), based on assessment of management systems and verifiable monitoring functionality gives an objective assessment of an individual ship?s performance irrespective of age or type. For the owners and operators this is a tool to set targets, monitor improvements and document their success across a range of performance benchmarks.

"Triple-E is more than a rating system, although it does provide an auditable ranking of green performance. Our intention is to provide this as a tool to bring tangible benefits to ships and the environment," says Svensen.

"The pressure to reduce pollution and greenhouse gas emissions is growing all the time and we intend to be at the frontline of this endeavour," he says. "The 15% emission reductions can be managed now by the existing fleet. When looking into the future and taking into account that further reductions can be achieved by new technologies, I am convinced that the shipping industry will be able to attain carbon neutral growth."
