China's Marintec Show Provides Setting for CIMAC Circle

Posted on December 14, 2009

CIMAC, the International Council for Combustion Engines, provided its "CIMAC Circle" series of forums at the recent Marintec trade show in Shanghai, China. Chaired by CIMAC board member Mr. Yasuhiro Itoh, managing director, Niigata Power Systems, the Circle was titled "Life Cycle Costs - the Impact of Fuel and Emissions". The forum provided the opportunity for a full spectrum of stakeholders to give a timely snapshot of present and predicted costs of engine ownership in light of tightening marine emissions legislation.

For the engine industry, Kjeld Aabo of MAN Diesel, Denmark and Mikael Troberg, Wärtsilä Industrial Operations, Italy reported on the technololgies under development that offer the best hope of meeting and possibly undercutting the stringent limitations of NOx prescribed in IMO Tier III for the Emission Control Areas (ECA).

On behalf of the oil and gas industries, Jerry Hammett, Shell Global Solutions GmbH, Germany emphasized ways and means of eliminating SOx emissions, in particular, the question of low sulphur heavy fuels versus distillates and refining versus scrubbing as methods of SOx abatement. Allan Wang, ABB Jiangjin Turbo Systems Limited, China reported on encouraging recent findings regarding single and two-stage high pressure turbocharging as an enabling technology of the strong Miller cycles which could go a long way to meeting IMO Tier III limits for NOx using only primary measures.

The was the third time the CIMAC Circle took place in China. This recent marine event provided a favorable setting to exchange knowledge and experience between the fastest growing ship and engine nations and the more well established centers of engine technology.
