HONG KONG shipowner Tai Chong Cheang Steamship (TCC) and the University of Southern California have developed a new system for ships that has shown in a series of sea trials to cut nitrogen oxide emissions at the point of exhaust 90 per cent and reduced particulate matter up to 75 per cent.
The technology uses tailored electrical nano-pulses to change the underlying chemistry, either at the point of exhaust or during combustion, reported Maritime Executive of Fort Lauderdale, Florida.
The dramatic improvement in efficiency was achieved using the radically different and more cost effective approach of nano-pulse power, compared to the standard scrubbers typically used on vessels that require training for crews and maintenance.
The researchers have also conducted tests using the same technology towards improving the combustion efficiency in marine diesel engines so that they can operate at their optimal continuous rating output.
The emissions research project was initiated and funded by TCC under the leadership of chief executive officer Kenneth Koo, as a corporate social responsibility initiative.
Said Mr Koo: "We believe that this game-changing solution will allow owners and managers to unshackle themselves from the present constraint of slow steaming as the only means to realise lower fuel consumption."
He noted that marine diesel engines were not designed to operate at very low power output and he argued the industry must go back to the basics by addressing combustion efficiency thus enabling solutions to be demonstrated to reduce and recover emissions from ships before they are emitted.
"The potentially catastrophic damage that such commercial practices causes, not only premature wear and damage to marine diesel engines through abnormally prolonged navigation under very low RPM and very low output condition but it also causes accelerated damage to other machinery components and systems," Mr Koo added.
