*  *  *  *  *  * October 19
Topic:          SeaPerch
Speaker:     Susan Nelson
Location:    Alameda, CA
Abstract:     Have you thought about reaching out to your local schools to educate them about careers in Naval Architecture, Marine, Ocean, and Naval Engineering, but didn't know where to start?  Have you heard the term STEM?  K-12 Outreach?  Are you interested in giving back to your profession at this point in your career?  Are you passionate about the USA's math and science placement in the world?  
 
If so, then we invite you to attend this meeting and learn about the SeaPerch Program, what has become the Navy's signature K-12 Outreach program to help find the next generation of Naval Architects, Marine, Ocean, and Naval Engineers, ROV experts, as well as other marine-related careers.  To learn more visit http://www.seaperch.org/index

*  *  *  *  *  * November 9
Topic:          The WindFloat I Project
Speaker:     Alexia Aubault
Location:    Montclair Bistro, Oakland, CA
Abstract:    The WindFloat is a floating foundation for a wind turbine, invented by Berkeley-based Marine Innovation and Technology and commercially developed by Principle Power Inc. The first of its kind was just installed in Agoucadoura, off the North coast of Portugal in October 2011. This prototype is equipped with a 2MW wind turbine which will be connected to the Portuguese electrical grid.

The design and fabrication of the first WindFloat took 2 years. Building a prototype brings on particular technical and organizational challenges, which will be discussed at the presentation. Companies of very different core business - wind turbine manufacturer Vestas, Portuguese electrical distributor EDP, pressure vessel manufacturer ASM and Portuguese shipyard MPG - were brought together to build the WindFloat. Both design and fabrication phases were reviewed by ABS.

A prototype is a bit of a research project - and as such is packed with instrumentation. In the next two years, WindFloat I will be closely monitored. In the meantime, people are already thinking about the next phase and how to best mass produce WindFloats...

*  *  *  *  *  * December 14
Topic:          The Deepwater Horizon Oil Spill: The Response from BP & Lessons Learned
Speaker:     Bill Tageson
Location:    Spice Monkey, Oakland, CA
Abstract:     This month's presentation will be given by Mr. Bill Tageson of Tageson Maritime Consulting who will be discussing his work as an expert adviser to BP during their response to the Deepwater Horizon oil spill in the summer of 2010. While deployed to the Gulf Coast, he surveyed the spill area, developed strategies for deployment of federal recovery equipment, and used his experience in salvage and oil spill response to influence joint incident command representatives to make response decisions that were feasible in the field. He will discuss his opinions on the effectiveness of the response and lessons learned.

January 11, 2012
Topic:          IMO EEDI: Impact on Ship Design
Speaker:     Keith Michel, Spencer Schilling
Location:    Pasta Pelican, Alameda
Abstract:     IMO has adopted the Energy Efficiency Design Index (EEDI), which imposes minimum propulsion efficiency requirements on newbuildings.  The regulation applies to ships for which contract signing occurs on or after January 1, 2013, or which are delivered after July 1, 2015. This presentation will provide a brief overview of the EEDI, and then describe how the EEDI is expected to impact the design of ships as the regulation becomes increasingly more rigorous.  The presenters will review existing best practice for containerships and crude oil carriers, and project what can be achieved through further optimization of the hull and propulsion systems, and through application of energy efficiency devices.  The influence of fuel oil price, vessel utilization, and ship speed will be discussed, as the owner considers tradeoffs to satisfy the EEDI while seeking to maximize return on investment.

February 22
Topic:          Hydrodynamic Performance of a Compound Cylinder Extracting Ocean-Wave Energy
Speaker:     Christophe Cochet
Location:    University of California, Berkeley
Abstract:     The ocean-wave energy converter being developed at UC Berkeley is modeled as a moored two-component vertical cylinder, with the outer cylinder sliding along a tension-tethered inner cylinder. With nonlinear rigid-body dynamics, it is first shown that the surge and pitch degrees of freedom are decoupled from the heave motion. The coupled surge-pitch motion can be solved and provide the contact forces between the cylinders. Earlier works of Chau & Yeung (2010, 25th Intl Workshop on Water Waves and Floating Bodies [25IWWWFB]), and Yeung (1981, Applied Ocean Research) are used for the hydrodynamics of the heave-motion study of the outer cylinder. The concept of capture width is used to characterize the extent of energy extraction: its maximization leads to optimal energy capture. The methodology presented yields the optimal geometry in terms of non-dimensional proportions of the device. It is found that a smaller radius and deeper draft for the outer cylinder will lead to a larger capture width and larger resulting motion. The results are compared to some existing designs of wave-energy absorbers.

March 14
Topic:          America’s Cup Organizing Committee
Speaker:     Mr. Robert Billingham
Location:    S.S. Jeremiah O’Brien, San Francisco, CA
Abstract:      This month's presentation will be given by Mr. Bob Billingham of America’s Cup Organizing Committee who will be discussing plans and development for hosting the America’s Cup 34 in San Francisco in 2013. He will also be addressing general topics of the AC45 and AC72 design rules and the boat building technology.

*  *  *  *  *  * April 11
Topic:          Ship Breaking at Mare Island Drydocks
Speaker:     Mr. Victor George & Mr. Werner Hoyt
Location:    Zio Fraedo’s, Vallejo, CA
Abstract:     The speakers will be discussing the process of recently reopening the shipyard at Mare Island after having been closed as a Naval Shipyard since 1996. They will address engineering efforts associated with reopening the yard, regulatory obstacles overcome throughout the 4-year process, and current ship breaking projects.

*  *  *  *  *  * May 16
Topic:          Navy after Next:  Building for Future Threats
Speaker:     LT Robert Blancard (USN) and LT Matt Malinowski (USN)
Location:    Pyramid Brewery, Berkeley, CA
Abstract:     A presentation will be given by LT Robert Blanchard and LT Matt Malinowski on the Total Ship Systems Engineering (TSSE) Project Team, a study combining a threat assessment, threat mitigation, and capabilities gap assessments to determine areas of weakness in the US Navy arsenal and how to address them.  Upon completion of the capability gap assessment, the project team developed HAVOC, a High-speed Autonomous Vehicle Ocean-going Catamaran.  HAVOC serves as a mothership for unmanned surface vehicles (USVs) and unmanned aerial vehicles (UAVs). The HAVOC concept provides greater detection range, stand-off distance, and weapons firing capabilities to combat the anti-ship cruise missile (ASCM) and fast attack craft/fast in-shore attack craft (FAC/FIAC) threats.
