SNAME Report Covers SOx Emissions Reduction
The Society of Naval Architects and Marine Engineers (SNAME) has published a new technical report that provides recommendations on technologies, practices and fuels that control and reduce sulfur oxide (SOx) emissions. Limitations on SOx are currently in place with more stringent regulations coming in the near future. Designed to assist with SOx management and reduction on ocean-going vessels, Marine Vessel Environmental Performance (MVEP) Assessment Guide Air Emissions: Sulfur Oxides (SOx) provides options for assessing emissions performance along with a standard methodology for determining SOx output from a vessel. Marine Vessel Environmental Performance (MVEP) Assessment Guide Air Emissions: Sulfur Oxides (SOx) was written by Mark West and Brian Ackerman…
MVeP Phase 2 Seeks Authors
The Marine Vessel Environmental Performance (MVeP) Assessment was presented November 4th, 2010 at the SNAME Annual Meeting. This is the work of SNAME T&R Panel EV-10 previously Ad-hoc Panel 19. Eleanor Nick Kirtley and Tim Leach of the Glosten Associates presented to an audience of about 50. The Glosten Associates also featured MVeP at their booth in the Expo where many conference attendees were able to speak with the presenters and other participants including Matt Winkler, VP of Seaworthy Systems – Roll Royce. In Phase 1, MVeP developed a checklist of environmental impacts resulting from marine vessels. Each impact can be assessed on its own merit, and the compilation of all assessments makes clear the trade-offs of various measures giving a holistic view of the ship’s performance.
The Lure of the Electric Drive
By Stuart C. Karon and Dr. In the September 2002 issue of Maritime Reporter and Engineering News, a detailed discussion was featured on the advantages of future High Temperature Superconductor (HTS) machinery for propulsion of electric drive ships. • Motors A 5-MW 230-rpm machine for the U.S. Navy's Office of Naval Research (ONR) is undergoing factory tests. ONR is now funding the next step - design, fabrication and factory testing of a 36.5-MW 120-rpm machine to prove the technology at full-scale for warships. • Generators Development of HTS generators has also leapt ahead with the initial production of 10-MVAR synchronous condensers for utility voltage adjusting service. These condensers are very similar in design and operation to 10-MW, 1,800-rpm generators.
