Shipowners can reduce air emissions up to 15% from ships, using available technology on today’s ships, according to Tor Svensen, COO of DNV Maritime, without incurring additional costs. Speaking in the day before the start of NorShipping 2009, Svensen is urging shipowners to thoroughly review all aspects of their operation in order to reduce emissions and to save money. “There is no reason to wait … in fact, we cannot wait,” he said.
DNV contends that ships from all market segments can reduce their air emissions by carefully analyzing and optimizing a number of individual operations, such as optimizing engine performance, optimizing trim for all drafts and speeds and the propulsion system efficiency and improving voyage management . In particular, he singled out the containership segment as having the greatest potential for immediate savings, nothing the magnified benefits on these generally very large, fast ships.
EEE
In addition to the reduction of air emissions from ships, DNV has recently released a new tool, the DNV Triple-E (Environmental & Energy Efficiency Rating Scheme), has also been developed to obtain measurable improvements for individual ships.
The DNV Triple-E, based on assessment of management systems and verifiable monitoring functionality is designed to provide 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,” said Svensen. The shipping industry, he said, must strive to achieve ‘carbon neutral growth.’
