80 World Bunkering Autumn 2010 Wärtsilä develops low- emissions engine Wärtsilä, ABB and HUG are cooperating on the joint development of next generation low emissions technology that will increase efficiency while lowering NOx emissions. In April this year, Wärtsilä and ABB Turbo Systems announced their cooperation in a joint development programme for a new and groundbreaking application of two- stage turbocharging on large diesel engines. The application of two- stage turbocharging technology on Wärtsilä diesel engines has been developed through close cooperation between the two companies. In this programme, Wärtsilä is focusing on developing advanced engine technology, which with the turbocharger is able to reach the highest possible performance and become a cost- effective commercial solution for its customers. ABB Turbo Systems is delivering the turbocharging technology with defined performance in terms of airflow, pressure ratios and efficiency. In an extension of this cooperation, after- treatment specialist Hug Engineering, based in Elsau, Switzerland, is to join the project. The new joint project is to develop an innovative compact selective catalytic reduction ( SCR) system especially tailored to operation with two- stage turbocharging. Wärtsilä, ABB Turbo Systems and HUG Engineering will target a further expansion of flexible engine operation at reduced NOx emis-sions and optimised fuel consumption, as well as targeting savings in first and life cycle costs. By combining their expertise and resources, the partners hope to achieve early readiness for market. RINA introduces LS rules The technical committee of classification society Registro Italiano Navale, ( RINA) has outlined new additional class notations for com-mercial ships using low- sulphur fuel. The new Low Sulphur Fuels ( LSF) notation, reflects the introduc-tion of Emissions Control Areas ( ECAs) and current national and international rules such as EU Directive 2005/ 33/ EC, the California Code of Regulations ( CCR) and MARPOL Annex VI, all of which are designed to achieve a progressive reduction in the sulphur content of marine fuels. The new class notation will be assigned to both new and existing ships whose machinery uses low- sulphur- content fuel. The list of machinery and percentage of sulphur content in the fuel used will be recorded in ship survey documents. Laser emissions monitoring system launched WR Systems, Ltd. ( WR) has announced the release of a second generation laser- based marine emissions monitoring system. The system will be formally launched at the SMM Exhibition in Hamburg in September. According to the company, Emsys is the world's first QCL ( Quantum Cascade Laser)- based, fully extractive, combined emissions and particulate matter ( PM) monitoring system. It has been designed to be compliant with MARPOL Annex VI, the NOx Technical Code, and ECA requirements. Emsys is installed within the funnel space, but is unique in that it monitors PM emissions " outside the stack". The system is the first production system to incorporate QCL technology. The laser can monitor multiple gases and is designed to be relatively maintenance-free. Combining highly accurate measurements with a unique gas path design eliminates many of the problems associated with traditional extractive and in- stack technology. The compact configuration greatly decreases installation time; correspondingly, installation costs are significantly lower than first generation extractive systems, WR claims. Emsys is designed and tested for continuous operation in multiple engine applications, and provides PM measurements in mg/ m ³ and g/ kWh. Conventional gaseous measurements include NOx, Equipment and services A round- up of news for the bunker industry - what's new, what's useful, what's changed? equipment and services
