Chair: CDR Scott Kelly, Chief Engineering Division, Marine Safety Center, U.S. Coast Guard
- Fuel Cell Passenger Ship in Commercial Service
Mr. Manfred Limbrunner, Proton Motors, presents overview of the FCS Alsterwasser, the world’s first commercial fuel cell passenger ship. It is a single-hulled, 100 passenger, ship propelled by hydrogen fueled PEM fuel cells that emits no CO2, NOx, SOx or particulate matter. The propulsion plant contains a hybrid electric drive which uses fuel cell output for base load and batteries for surge load. The paper will outline design and regulatory challenges associated with constructing the vessel, including high pressure storage and delivery of hydrogen as fuel.
- Application of Certification/Safety Experience Gained in Fuel Cell Public Transportation with Buses towards Marine Applications of Fuel Cells
Mr. Daljit Bawa & Dr. Jake DeVaal, Ballard Power Systems, Inc., present various standards and safety concepts used in the approval process of public transportation using fuel cell buses and the adaptation of lessons learned to marine applications. Fuel cells with hydrogen fuel have now been demonstrated in public transportation for over 15 years worldwide. During this time Ballard-powered fuel cell buses have clocked more than 300,000 hours while accumulating over 5 million km.
- Use of LNG and fuel cell technology in Offshore Support Vessels (OSV) Ships
Mr. Jan Fredrik Meling, Eidesvik Offshore AS, reviews how ships contribute to a great extent to local pollution such as NOx, SOx, and particle matter. In addition, emission of CO2 from ships is an issue. Dual fuel engines (marine gas oil or LNG) have been available for nearly 10 years. However, there are still only 4 OSVs using this technology which more or less eliminates local pollution and reduces CO2 emissions by 20%. In addition, modern fuel cell technology is considered to represent an important future possibility for environmentally friendly energy production in ships. How can we as an industry create demand for these technologies?
- B31.12 Hydrogen Piping and Fuel Cells for Marine Application
Mr. William P. Collins, UTC Power, discusses the potential to use fuel cell technology for marine applications. Coverage includes the types of fuel cells and their applications, fuels currently used by various fuel cell designs, the status of supporting product safety standards, the existing model and design codes for the storage and piping of various fuels, the existing model and design codes for the dispensing of various fuels, and potential near term applications for powering marine vessels and other equipment.
- On Board Storage Utilizing Composite Reinforced Pressure Vessels in ISO Tank Container Format for CNG Fueled Ro-Ro Ships
Mr. David Lawrence, Floating Pipeline Company, Inc., presents the use of tank containers incorporating multiple element gas containers (CRPVs) built to ISO 1496-3:1995 for use in fueling CNG marine propulsion systems. An overview of the container and piping technology as well as design studies by Robert Allan, Naval Architects, for a CNG powered vehicle ferry (Ro-Ro) incorporating the tank container(s), piping and support structure will be presented.
- Hybrid-Powered Marine Vessels
Mr. Paul Jamer, Aspin Kemp & Associates, and Ms. Susan Hayman, Foss Maritime Company, present the 2009 entry into service of Foss Maritime’s Carolyn Dorothy, the world’s first hybrid-powered tugboat, as a watershed event. The vessel incorporates a radically different propulsion scheme from its historical predecessors – using auxiliary generators and storage batteries, as well as smaller main engines. The authors will discuss actual operating experience including fuel and maintenance savings as well as reduced noise. The challenges of testing emissions of a hybrid powered vessel will also be detailed. The applicability and benefits for retrofitting existing vessels will be examined.
- Cold Ironing for Commercial Ships
Mr. Thane Gilman, P.E., U.S. Coast Guard, presents how standards for design, installation and operation of ship shore power connections were developed in response to demands from port communities across the world requiring reduced emissions from marine engines while in port. One option for reducing emissions is for the ship to secure its ship service electrical generators and receive power from onshore power supply (OPS) sources, a process also known as "cold ironing". This paper discusses the implications of and best practices for OPS from the vantage point of the ship owner/operator, as well as the port authority, facility, and potential power supplier. Development of international standards will enable the OPS option to be employed quicker, in numerous locations, for the most global of industries – shipping.
- Panel Wrap-Up: Evaluation of Fuel Cell and Gas Fueled Ships
CDR Scott Kelly, U.S. Coast Guard, moderates a panel discussion on the existing regulatory framework for small passenger vessels and offshore supply vessels relevant to fuel cells, including high pressure composite storage of hydrogen, storage of natural gas and associated fire protection issues. A question and answer session for panel presenters will also be included.
1700 – 1830: Reception
Friday, July 30, 2010
0800 – 1005: Emerging Technology Panel
Technologies that facilitate reduction of environmental impact of shipping.
Chair: Mr. Wayne Lundy, Systems Engineering Division, U.S. Coast Guard
- A Review of Ballast Water Management Technologies
Mr. Jon Stewart, International Maritime Technology Consultants, discusses how development of ballast water management systems is in a period of unprecedented growth. According to Lloyd’s Register, there was a 42% increase in companies providing technical information for their Ballast Water Treatment Technology Guide publication between the September 2008 edition and the February 2010 edition. As of March 2010, there are 48 documented treatment systems in some stage of development or implementation. Numerous others are in early stage development with no details currently available. With the recently announced US Ballast Water Discharge Standard now under review it is important to consider how technology development will or will not facilitate compliance with the proposed standard. The presentation will examine the circumstances of the current capability and status of technology and the associated market development along with considerations of the potential to meet the proposed Phase 2 standard.
- Technology Implementation at the Port of Los Angeles – Moving from Current to Emerging Technologies
CAPT John M. Holmes, U.S. Coast Guard (Ret.) and Deputy Executive Director, Port of Los Angeles, explores the strategy that the Port of Los Angeles developed to implement their nationally recognized Clean Truck Program, and their continuing efforts to move from current technology to implement emerging and developing technologies in the maritime transportation area. The session will examine the technologies that have been implemented to date and the Port's continuing plan for technology implementation to meet the California AB 32 targets for Greenhouse gas emissions. The session will examine their efforts in the areas of drayage trucking, yard equipment, and vessels.
- Emerging Technologies for Treating Contaminants in Marine Wastewater
Dr. Don Nguyen, Coffin World Water Systems, presents how contaminants in marine wastewater facing current or near-future regulations can be broadly categorized to free oil & suspended solids, emulsified oil and dissolved solids, and biological organisms. The first category of contaminants has been treated by commercially available OWS systems. The second class of contaminants, emulsified oils and dissolved solids, has been effectively treated by UF membrane filtration. A survey of recent advances in physical and chemical demulsification technologies to enhance emulsified oil removal with less reliance on membrane was conducted. The study also identified new applications for treatments of biological organisms in ballast water.
- A Review of EGCS Technology for Compliance with SOx ECAS and Regional Sulphur Oxide Emission Rules
Mr. Donald Gregory, Exhaust Gas Cleaning Association, presents key highlights including a review of identified regulated emissions as well as currently unregulated emissions that have been identified for future consideration. This review will include a brief focus on sources/causes of emissions from diesel engines and some of their hypothesized impacts. The presentation will include how SOx abatement EGCS technology provides the additional benefits of reductions of some non-SOx emissions. A comparison will be made between the benefits of the use “end of the stack solutions” compared to the use of the specified fuel solution both for current and projected future emissions regulations. The presentation will conclude with a review of all EGCSA members' technologies, which will include the operating principles of each technology, the current state of each technology’s development and if available, the latest test results and approvals.
1020 – 1200: Codes & Standards Panel
Voluntary consensus codes & standards that address marine technologies for green ships and offshore energy development.
Chair: Mr. Harishbhai Patel, Manager Emerging Technologies Department, American Bureau of Shipping
- Use of ASME Section X Code for High Pressure Vessels
Dr. Norman L. Newhouse, Lincoln Composites, Inc., and Mr. George Rawls, Savannah River National Laboratory, discuss the ASME project to meet industry needs for pressure vessel Code updates to address storage of high pressure hydrogen. This has resulted in updates to existing B&PV Code, Code Cases, and new Code requirements. One of the tasks was to develop requirements for high pressure composite reinforced vessels with non-load sharing liners. Originally developed as a Code Case, the requirements have been approved as mandatory Appendix 8 of ASME Section X of the B&PV Code, to be published in 2010. The allowed pressures of this new Code are from 3,000 to 15,000 psi. Qualification testing addresses expected operating conditions. Inspection requirements are being developed in cooperation with NBIC. Pressure vessels are being developed that meet the new ASME requirements. Efforts will be made to include additional gases, including compressed natural gas, and additional operational requirements in future revisions of the Code.
- Use of ASME Code Section XII – Transport Tanks
Dr. Allen Selz, Pressure Sciences, Inc., and Mr. Daniel Sharp, ASME discuss Section XII of the ASME Boiler and Pressure Vessel Code, developed at the request of the US Department of Transportation to address rules for the construction and continued service of transport tanks for the transportation of dangerous goods by road, air, or water. The standard is intended to be referenced in the federal hazardous material regulations, Title 49. While the majority of the current requirements focus on over-the-road transport, there are rules for cryogenic portable tanks, used in marine applications for the transport CNG; helium; and other liquefied gases, and for ton tanks used for rail and barge shipping for the transport of chlorine and other compressed gases. Rules for non-cryogenic portable tanks are currently provided in Section VIII, Division 2, but will be moved into Section XII. These portable tank requirements should replace the existing references to ASME Section VIII, Division 1 in Title 46 of the Code of Federal Regulations.
- Composite Pressure Vessels for Marine and Land Based Applications
Dr. Norman L. Newhouse, Lincoln Composites, Inc., and Mr. Harish Patel, American Bureau of Shipping, present how composite pressure vessels have been used for over 40 years in a variety of military, aerospace, marine, transportation, stationary, and vehicle applications. Codes, standards, and guidelines have been developed to address vessel performance in these high pressure applications, including by ASME and ABS. Qualification testing in these standards addresses expected operating conditions, with a significant amount of common testing requirements. A risk or hazard identification analysis may be conducted during qualification and approval. Periodic inspection of vessels mitigates risk, particularly in terms of detecting environmental and mechanically induced damage before failure can occur. Knowledge has been gained from qualification testing, field experience, and inspection that supports selection of materials and design configurations for marine and land based applications.
- ASME Code Section VIII, Divisions 2 and 3 Rules for Construction of Pressure Vessels
Mr. Louis E. Hayden, Louis E. Hayden Associates, and Dr. J. Robert Sims, Becht Engineering Co., Inc., discuss how the need for more efficient and cost-effective design of shipboard equipment has never been greater. Pressure vessels aboard ships can account for significant volume and weight, and thus, affect the overall performance of the vessel. Classically shipboard pressure vessels have been designed to ASME Section VIII, Division 1. This design code provides a safe pressure vessel using a basic design-by-rule approach with a 3.5 to 1 design safety factor. In recent years, the ASME Section VIII pressure vessel committee has developed two design codes, Section VIII, Division 2 Alternative Rules for Construction of Pressure Vessels and Section VIII, Division 3, Alternative Rules for Construction of High Pressure Vessels. These pressure vessel design codes offer lower design factors, an improved design-by-rule approach and allow or require design by analysis based on the vessel operating conditions and environment such as cyclic service. Use of these codes can improve shipboard vessel design by lowering weight of vessels while providing a safe, reliable pressure vessel.
1325 – 1415: Regulatory & Classification Panel
Review of issues presented during the workshop including those applicable to standards and regulations. Description of USCG rulemaking process.
Chair: Mr. Jaideep Sirkar, Chief Naval Architect Division, U.S. Coast Guard
- Shipboard Technology Evaluation Program (STEP)
LCDR Brian Moore, U.S. Coast Guard, discusses the Shipboard Technology Evaluation Program (STEP) that facilitates the development of effective ballast water management system technologies in order to create more options for vessel owners seeking alternatives to ballast water exchange. This voluntary, no cost program allows vessels to install experimental treatment systems that can be granted an equivalency to future ballast water discharge regulations for up to the life of the vessel or the system.
- Adoption of Standards in Regulations – OMB circular A119/National Technology Transfer Act and Rulemaking Process/Related Proposed Rules.
Mr. Jaideep Sirkar, Chief Naval Architect Division, U.S. Coast Guard, discusses the Government mandate to use voluntary industry consensus standards in lieu of government-unique standards/regulationsm, the USCG rulemaking process, including submission of public comments. Overview of relevant proposed rules: Outer Continental Shelf Activities (64 FR 68416, 7 Dec 99); and Standards for Living Organisms in Ships’ Ballast Water Discharged in U.S. Waters (74 FR 44632, 28 Aug 09). Further discussion existing regulations relating to green ship technology (e.g., fuel cells, gas fueled ships).
- Compliance Issues with Pressure Equipment in Service
Mr. Wayne Lundy, P.E., U.S. Coast Guard, and Mr. Harish Patel, American Bureau of Shipping, discuss functional requirements for pressure vessels intended for use on ships and fixed offshore platforms. Establishing the functional requirements for pressure vessels based on factors like service, location, and operating parameters will help designers and regulators determine the acceptability of pressure vessels built to standards other than those prescribed by regulation.
