FALL 2002 - SPRING 2003 SCHEDULE
MEETINGS SYNOPSIS
September 19, 2002
Topic: Head Sea Parametric Rolling of Post-Panamax Containerships Speaker: R. Keith Michel, Herbert Engr. Corp. & J. Randolph Paulling Location: Pasta Pelican Restaurant, Alameda CA Abstract: In October, 1998, a post-Panamax C11 class containership encountered extreme weather and sustained extensive loss and damage to deck stowed containers. The motions of the vessel during this storm event were investigated through a series of model tests and numerical analyses, providing insight into the conditions likely to produce parametric rolling in head seas, and the magnitude of motions and accelerations that can occur. The findings from this investigation are presented, together with discussion on how such extreme motions impact the design and application of container securing systems. The presentation includes video of the model tests and time domain simulations. Recommendations for additional research needed to better understand the influence of vessel design and operational considerations on parametric rolling are also provided.
Topic: Tour of US Coast Guard Buoy Tender USCGC ASPEN Speaker: Lt. Steve Matadobra, USCG, Executive Officer, USCGC ASPEN Location: Ship & Point Welcome Room, Coast Guard Island, Alameda CA Abstract: The 225' USCGC ASPEN (WLB-208) was commissioned in January, 2002 as one of the newest in the Coast Guard's Buoy Tender Replacement Project, a major acquisition to replace the WW II era 180' buoy tenders. With a 46 ft beam, 13 ft draft, at 2000 tons, the 225' WLB represents the latest in shipbuilding, propulsion and ship control technology, some of the features being a single controllable pitch propeller, bow and stern thrusters, a GPS controlled Dynamic Positioning System, and a Machinery Plant Control and Monitoring System.
Topic: Design and Construction of the SWATH AGOR 26 R/V Kilo Moana Speaker: Terry W. Schmidt, Director, and Jeff Kline, Program Manager, Advanced Marine Platforms, Lockheed Martin Corporation Location: Spenger's Restaurant, Berkeley CA Abstract: The R/V Kilo Moana (AGOR 26), a general-purpose oceanographic research vessel, is part of the nation's University National Oceanographic Laboratory System (UNOLS) vessel fleet. She is performing onboard data processing and analyses; sampling and collection of air, surface, midwater, and sea floor parameters; full ocean depth sea floor surveys; launching, towing, and recovery of science packages, tethered remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs); and deployment and recovery of deep-sea moorings. AGOR 26 is fully operational in upper sea state 6, with precise navigation, station-keeping, and track-line maneuvering capabilities in both deep sea and coastal operations, and for long periods of time at low speeds. The ship has a Small Waterplane Area Twin Hull (SWATH) form, based on semi-submersible offshore rigs that are designed to provide a working platform with diminished motions in open seas, exposing only a minimum of the ship to the lifting forces of the waves. The AGOR 26, the first US Navy owned SWATH oceanographic research ship, arrived at the University of Hawaii Marine Center on September 3rd.
January 16, 2003 Topic: SS CAPE MOHICAN Grounding and Repair Speaker: Greg Thornton, Western Region, MARAD Location: Spenger's Restaurant, Berkeley CA Abstract: The SS CAPE MOHICAN of the Military Sealift Command went aground May 21, 2001 off the coast of South Korea, requiring 1500 tons of steel to make the ship seaworthy again. The presentation will discuss the salvage work and emergency drydocking to accomplish this repair work. The Cape Mohican is the ex TILLIE LYKES, a Sea Bee class cargo-barge carrier built in 1973 at General Dynamics, Quincy, Massachusetts. She is 873 ft long, 18,800 t. light displacement, with a single screw steam turbine.
February 13, 2003 Topic: San Francisco Bay Ferries: The WTA's Implementation and Operations Plan Speaker: Mary Frances Culnane, Manager, Marine Engineering, San Francisco Bay Area Water Transit Authority Location: Sinbad's Restaurant, San Francisco CA Abstract: The Water Transit Authority (WTA) was created by California state legislation in 1999 to create a plan for expansion of ferry service on San Francisco Bay. Two aspects of the legislation included performing an Environmental Impact Review (EIR) of the potential expansion of ferry routes, as well as creating an Implementation and Operations Plan (IOP) detailing how new routes would be selected, when they would become functional, what type vessels would serve on those routes, and how they would be financed. The presentation includes details of the WTA's Implementation and Operations Plan (IOP) including the boats, facilities, costs, safety aspects, and computer model simulation of future ferry routes.
March 13, 2003 Topic: Small Shallow Water Hovercraft (Student Paper) Speakers: Cameron Clark, Shawn Lee, Lester Frank; California Maritime Academy Location: California Maritime Academy Dining Facility, Vallejo CA Abstract: The Student Speakers are building a small hovercraft as part of their senior design project. This craft is designed to rescue people in shallow water or in swampy areas. This design project is part of the graduation requirements for the Mechanical Engineering program at CMA. The speakers will discuss the design process as it is related to designing and building this small hovercraft. Design trade-offs and real construction problems will be discussed. The hovercraft will be available for inspection.
Topic: Vortex Induced Vibration in the Oil Patch Speaker: Owen H. Oakley, Jr., ChevronTexaco Exploration & Production Technology Co. Location: Tony Roma's Restaurant, Oakland CA Abstract: This presentation addresses the issue of the prediction of vortex induced vibration of deepwater risers and floating structures. Highlights include: the importance to offshore operations, experimental measurement programs and computational fluid dynamic initiatives.
Topic: Tour of M/V CORAL PRINCESS Machinery Plant Speaker: tour guides Location: Cruise Ship Terminal, Pier 35, San Francisco CA Abstract: This exciting new 88,000 GRT, 1,974-passenger vessel made its debut in January of 2003. The M/V CORAL PRINCESS offers 85% outside staterooms, most with private balconies and features an innovative power generation technology -- a combination of diesel engines and gas turbines. We will have the opportunity to tour the machinery plant.
