T&R SESSION: Marginal Abatement Costs and Cost Effectiveness of Energy-Efficiency Measures
Thursday, November 4th; 11:00AM-noon in Regency G
Bruce Russell & Dave St Amand, co-chairs, SNAME T&R Ad Hoc Panel AHP-20 

The SNAME’s T&R committee Ad Hoc panel 20 on Green House Gases and Economics conducted in depth analysis of the cost effectiveness and potential for reducing CO2 emissions of technical and operational measures. This report had two primary purposes. The first was to develop a standardized methodology for examining measures to improve-efficiency on ships. The methodology was designed to estimate the cost effectiveness and potential for reducing CO2 emissions of each measure. The second objective was to apply the methodology to the 22 abatement measures for which good data were available. This analysis provided estimates of the potential for reducing CO2 emissions and associated marginal abatement costs for 14 types of new and existing ships. For each vessel type, size, and age, these cost estimates were plotted against the estimated potential for reducing CO2 emissions and the marginal abatement cost curves for each ship type were presented. Sensitivity analyses were also performed to examine the impact of fuel prices and discount rates on the cost effectiveness of the measures. Key findings should be of interest to policy makers, ship owners and operators, and other interested parties. Further work needs to be done on the actual in-service cost, reliability, variability, and effectiveness of these measures. SNAME’s Technical & Research Environment Engineering Committee will continue to evaluate these measures in a new panel on Cost Effectiveness of Energy Efficiency Measures EC-11 (to be established after the IMO MEPC 61 meeting).

T&R SESSION: Marine Vessel Environmental Performance Project
Thursday, November 4th; noon to 12:30 PM in Regency G
Eleanor Nick Kirtley, Kevin Reynolds, & SNAME T&R Ad Hoc Panel AHP-19 Chair Tim Leach

The Marine Vessel environmental Performance assessment is now in Phase II developing a T&R Bulletin on 35 environmental impacts grouped into 4 categories: energy efficiency, air emissions, water emissions, and general measures. A Performance Assessment Guide (Guide) is written and reviewed for each impact. The Guides define 4 standard performance levels: prerequisite, good: prescriptive measures, best: quantitative metrics, and a zero impact solution. MVeP is being developed to provide vessel designers, owners, operators, and other governing bodies with a standard methodology to assess the relative merits of environmental practices.

This presentation will feature:
• Introduction of MVeP project team, category captains, Guide authors, and Guide reviewers
• Update on the development of the 35 Guides
• Draft environmental impact performance levels
• Invitation to participate in MVeP 

 
T&R SESSION: A Guide for a Shipboard Oily Waste Management Plan
Thursday, November 4th; 12:30 PM to 1:00 PM in Regency G
Bruce Russell & Haluk Alper, co-chairs, SNAME T&R Panel EC-3 Oily Waste Water and Bilgewater

Company and shipboard compliance with MARPOL takes top management commitment to ensure properly functioning oily water separators, oily waste and bilgewater treatment systems. In turn, this takes thoughtful understanding of the shipboard oily waste stream and sources of bilgewater contamination; crew and shore side personnel awareness and training; adequate funding for maintenance, training and equipment maintenance, retrofitting and upgrades; attention to maintenance and operating procedures and details; and, careful monitoring, communication, and oversight. Another consideration or finding is based on the panel’s review of Oily Water Separator (OWS) regulatory mishaps and illegal discharges: management should provide all employees a universal, unambiguous and clear process for initiating a corrective process when there are problems. To these ends, a comprehensive Oily Waste Management Plan (OWMP) should be developed under a company’s Safety Management System or as part of a company’s optional quality or environmental management systems. While not intended to be prescriptive, this guide provides a process to assess the company’s existing planned arrangements and related oily waste water and bilgewater management systems. This guide also provides specific and detailed documented company procedures to develop key elements of the oily waste management plan. The Guide is organized into fourteen appendices, including guidance on initial auditing and ongoing system’s auditing. This OWMP builds on EC-3’s earlier work: SNAME T&R Bulletin 6-1 and adopted by IMO as IMO MEPC Circular 677 Guide to Diagnosing Contaminants in Oily Bilge Water to Maintain, Operate and Troubleshoot Bilge Water Treatment Systems. 
 

T&R SESSION: Presentations by the Marine Forensics Committee
Thursday, November 4th; 2:30PM-3:30PM in Regency G
William Garzke, Sean Kery, George Edwards, & Ben Fisher

The Marine Forensics Committee will have several short presentations for the Technical and Research Program at the 2010 SNAME Annual Meeting in Bellevue, Washington on 4 November 2010. There will be an announcement of the Marine Forensics Symposium in April 2012.

1) An overview and progress of the Guidelines for Marine Forensic Investigations soon to be published.
2) An overview and progress report on the sinking of the SS Edmund Fitzgerald using new simulation technology.
3) An overview and progress report on the loss of the USS Monitor using new simulation technology.

T&R SESSION: Presentations by the Dynamic Stability Task Group (DSTG)
Thursday, November 4th; 3:30PM-4:30PM in Regency G
Chris Bassler, Bill Peters, Vadim Belendy, and Bruce Johnson

The SNAME Dynamic Stability Task Group (DSTG) will have a series of technical presentations at the 2010 SNAME Annual Meeting in Bellevue, WA on November 4, 2010. The DSTG was established in the spring of 2008 to provide a forum for technical discussion, collaboration, and information review on matters related to dynamic stability. The DSTG presentations during the T&R session of the Annual Meeting will include:

1) Overview and Progress - Chris Bassler
2) International Standards - Bill Peters
3) Probabilistic Methods - Vadim Belenky
4) Scaling and Dimensionality - Bruce Johnson

 
T&R SESSION: Propulsion Shafting and Alignment
Thursday, November 4th; 4:30PM-5:30PM in Regency G
Panel Chair – Kevin Prince with Bruce Cowper, Neil Gallagher, Jan Anderson and Eric Diehl

This session will promote discussion and awareness of propulsion shafting alignment issues. Discussions are to focus on current issues that are of concern to industry; including ship owners, builders, consultants, and operators. The primary purpose is to present the issues and allow for expression of different views and experiences. It is not the intent to solve problems or promote services / companies.

Topics may include the following:
· Alternative monitoring techniques for outboard bearings
· Extending drydock periods for shafting inspection
· Accounting for the influence of hull deflection on shaft alignment
· Alignment of high speed shafting (> 900 RPM)
· Relative wear down of outboard bearings and influence on alignment: experience & theory
· Analysis/Measurement techniques: practical limitations, advantages, disadvantages, practical tolerances.
· Alignment strategy and procedures: costs, definition of “optimum”
· Accounting for the affect of eccentric thrust.
