MEETINGS SYNOPSIS
September 14, 2005
Topic: Designing Ships for the Movie "Pirates of the Caribbean 2" Speaker: Andy Davis, Naval Architect and President of Tri-Coastal Marine, Richmond CA Location: Pasta Pelican Restaurant, 2455 Mariner Square Drive, Alameda CA Abstract: "Pirates of the Caribbean 2" is purportedly the most expensive movie made to date, with a budget of $400 million. Tri-Coastal Marine has designed three full size ships for the film, all of which are operational to different degrees and are built with an innovative wood/steel composite method. "Black Pearl" (Captain Jack Swallow’s flagship) was built over an existing 1970’s era steel crewboat. It is fully operational and has traveled from Bayou LaBatre to Dominica in the West Indies and Freeport in the Bahamas. "Edinburgh" is a full size replica of the "Bounty," built on two barges, and was broken in half by a sea monster in the movie. "Flying Dutchman" is a 500-ton ghost ship and was built in three modules. A special motion basin 600’ x 400’ x 30’ was excavated at the sea front in the Bahamas. All three vessels are equipped with chainplates for attachment to active tethers in the floor of the basin, which will enable them to be maneuvered and to move with the simulated wave motion. The motion system has four large hydraulic cylinders; each with a 12' stroke and a pull of 200 kips.
Topic: USCG Naval Engineering Division, Maintenance & Logistics Command Pacific; Mission and Overview Speaker: CAPT Philip Sullivan, USCG; Chief, Naval Engineering Division, Maintenance & Logistics Command Pacific, Oakland, CA Location: El Torito Restaurant, 5 San Leandro Marina, San Leandro CA Abstract: The primary charter of the Naval Engineering Division of the Coast Guard’s Maintenance & Logistics Command Pacific is to manage the Hull, Mechanical and Electrical (HM&E) and Ordnance repairs, maintenance, and alteration programs for all cutters and standard boats in the Pacific Area. This includes providing technical information, training, and assistance to field units while also providing contracting and procurement services to all afloat units. The division is the recipient of the Commandant’s Quality Award (Bronze) in both 2001 and 2003 and has received multiple American Society of Naval Engineer awards for outstanding achievements and contributions to the Coast Guard Naval Engineering Program, along with multiple individual awards for our members. The presenter will also cover some of the division’s more successful practices and successes managing cutter and icebreaker overhauls and rebuilds and the recent move from Alameda to Oakland.
Topic: California Maritime Academy's Diesel and Steam Plant Simulators Speaker: Tom Mader, Assistant Professor, Marine Engineering Technology Department, California Maritime Academy, Vallejo, CA Location: California Maritime Academy, 200 Maritime Academy Drive, Vallejo, CA Abstract: The California Maritime Academy is a unique and specialized campus of The California State University. One of seven degree-granting maritime academies in the United States, Cal Maritime offers students a specialized education combining classroom instruction, experiential learning, and professional development in preparation for successful careers in the maritime industry. In addition to the operational and maintenance training Cadet engineers receive during summer training cruises, the Diesel and Steam Plant Simulators on campus provide hands-on demonstrations of marine propulsion plant technology. In these full-mission simulators Cadets engineers gain an understanding of integrated plant operations, learn fault analysis techniques and develop their communication and management skills in routine operations and casualty scenarios. A demonstration of Cal Maritime’s Diesel and Steam Plant Simulators will provide a close-up view of the cadet learning experience.
January 11, 2006 Topic: USCG Response Boat – Medium (RB-M) Acquisition Project; Mission, Overview, and Progress Speaker: CAPT Bryon Ing, USCG; Project Manager and MCPO Timothy Urban, Project Master Chief, Response Boat – Medium (RB-M); Response Boat Acquisition Division (G-ARB), US Coast Guard Acquisition Directorate, Washington DC Location: Pasta Pelican Restaurant, 2455 Mariner Square Drive, Alameda CA Abstract: The U. S. Coast Guard (USCG) RB-M Project is an effort to re-capitalize the capability of the existing multi-mission 41’ Utility Boats (UTB) and a small number of larger, non-standard boats that have replaced 41’ UTBs removed from service. The 41’ UTB is reaching the end of its service life. Engine and hull integrity issues head a significant list of platform shortfalls. The primary function of the RB-M project is to provide a boat that meets the current and projected multi-mission demand in the coastal environment. The project is expected to acquire approximately 180 boats and the logistics infrastructure necessary to support them. The RB-M Group works closely with the 47’ Motor Lifeboat (117 boats); and Small Response Boat Groups (expected to consist of 350 boats); both within the Response Boat Acquisition Division to provide the future US Coast Guard with an outstanding mix of modern efficient boats.
February 15, 2006 (3rd Wednesday) Topic: Resonant Modes of Rectangular Twin Hulls - Student Paper Speaker: Robert K.M. Seah, Ph.D. Candidate, Department of Mechanical Engineering, University of California at Berkeley Location: Seaborg Room, UC Berkeley Faculty Club, Berkeley, CA Abstract: The hydrodynamics of a moonpool between a pair of rectangular hull sections is examined. The sloshing modes, commonly associated with sway and roll motion are well known. Less well known are the symmetric resonant modes associated with heave motion. A semi-analytical formulation is developed to examine the zeroth-order mode, which is a Helmholtz or "piston-like" mode of motion of the water column in the gap area. Following a brief description of the theory, numerical values of the resonant frequencies are presented, particularly those associated with the relatively obscure Helmholtz mode. The behavior of the added-mass and damping coefficients near resonances are explained and quantified. Parameters considered include the moonpool gap-to-beam ratio, draft-to-beam ratio, and draft-to-water depth ratio. The issues are of fundamental interest to predicting ship motion of catamaran hulls.
March 8, 2006 Topic: Northrop Grumman Marine Systems Tour / High-Temperature Superconductor Generator Program Speaker: Reg Ricket, Advisory Engineer, Northrop Grumman Electronics Systems - Marine Systems (NGES-MS) Location: Northrop Grumman Electronics Systems - Marine Systems (NGES-MS), 401 E. Hendy Ave, Sunnyvale, CA Abstract: A Northrop Grumman Corporation-led team has been selected by the Naval Sea Systems Command (NAVSEA) to begin a design of a 40-megawatt (MW) high-temperature superconductor (HTS) generator intended to provide a smaller, lighter and quieter main power source for future surface combatants. As the U.S. Navy transitions to an all-electric surface ship, superconductivity will be a key enabling technology for achieving these power density goals. Conventional generators are heavy, large and noisy. HTS generators can be at least half the size and weight of currently available generators of equal rating, while providing low-noise acoustic signatures and increased system stability. This tour is for US Citizens only. Contact an officer for info.
Topic: LNG Vessels of the Future Speaker: Keith Michel, President, Herbert Engineering, Alameda, CA; and Peter Noble, Project Manager, Marine Engineering and Ship Construction for the Qatargas 3 Project, a joint venture between Qatar Petroleum and ConocoPhillips Marine, USA. Location: Spenger’s Fresh Fish Grotto, 1919 Fourth Street, Berkeley, CA Abstract: The next generation of LNG carriers is now on order in Korean yards, with the size of large LNG carriers increasing from 160,000 m3 to in excess of 200,000 m3. This presentation reviews the design options for such very large LNG carriers, and looks at the technical challenges and economic benefits of building even larger LNG carriers in the future.
Topic: SWATH Stability in High Speed Turns Speaker: Steven J. Schmitz, Marine Senior Design Engineer, Navatek Ltd. Location: Pyramid Alehouse & Restaurant, 901 Gilman Street, Berkeley, CA Abstract: Most seagoing surface vessels tend to bank out or away from the center of a high speed turn, SWATH ships are no exception. While the use of a conventional rudder is intended to produce motions in the yaw plane, the fact is unwanted motions are induced by cross coupling forces into the roll and pitch planes. SWATH vessels with dihedral planes, such as canards and stabilizers, more significantly experience these unwanted cross coupling forces. A new kind of ‘On Demand’ control surface can increase the yaw and pitch effectiveness of the vessel while significantly reducing or eliminating the unwanted roll out motion that is typical during a high speed steady turn. This presentation reviews the development of a 2 Degree of Freedom (DOF) rudder/stabilizer and its effect on a SWATH ship in a high speed steady turn.
