From the Chair:

Welcome to the Northern California Section representing The Society of Naval Architects and Marine Engineers in Northern California and Western Nevada.

We strive to provide presentations of interest to our members and guests. Meetings are monthly from September until late Spring jointly with ASNE and occasionally with the Port Engineers at locations varying from San Francisco and Oakland to Vallejo or Sunnyvale. The usual meeting format includes a social hour, dinner (sometimes lunch), presentation and Q&A period. Several meetings each season are field trips to industry landmarks. Our meetings are usually the Second Wednesday of the month unless noted.

We are always in need of volunteers. If you wish to volunteer, please use the "Contact Us" link. If you receive your announcements by mail, please let us know your email address. This will speed up notification and save on section mailing costs. 


Upcoming Events

  • Northern California - Evaluating Practical Options for Zero Carbon Ships

    Wednesday, March 11, 2020, 6:00 PM - 9:00 PM PT
    Please join us on Wednesday, March 11th from 6:00 pm - 9:00 pm on-board the Commodore Cruises vessel Cabernet Sauvignon where Rog Tagg will be presenting on the Evaluating Practical Options for Zero Carbon Ships.

    Ship designers, builders, owners, and operators need to understand and come to terms with the task ahead and to effectively assess their options for a transition to low carbon operations over the next 10 to 15 years. LNG, speed reductions, and improvements to the energy efficiency of ship designs will not be enough to meet the IMO 2030 and 2050 GHG reduction targets. Low carbon fuels and extensions of current technology will be required to meet these goals. There are many developing technologies offering alternatives to traditional carbon-based fuels. Some of these show promise for particular ship types and services. It is likely that no single fuel or storage technology will dominate the future marine industry as oil does now. This presentation gives a brief overview of available and future fuel technologies, and a realistic look at technologies applicable to different ship types and sectors. Some examples of how to assess these technologies for ship types and services are provided to help answer the questions of why some technologies may work and some may not. Sample assessments are reviewed for specific maritime sectors in including long haul container liner service, feeder containership, short haul services, and variable load services are used as examples. What might a near zero carbon ship built 2030 look like, what are the technical and cost challenges, and what key gaps in technologies needed to be filled to get there?

  • Northern California - Littoral Combat Ship USS Independence

    Wednesday, April 22, 2020, 6:00 PM - 9:00 PM PT
    Please join us on Wednesday, April 22nd as retired CMA Professor Al McLemore presents the Littoral Combat Ship USS Independence.

    In 1999, Austal USA Shipyard delivered the Littoral Combat Ship USS Independence to the U.S. Navy. The ship incorporated many new concepts for the Navy, including all aluminum construction, trimaran hull, and significant crew size reduction through the use of automation. This presentation will give, from an operators viewpoint, some background of the Australian company Austal and the construction, launching, and operation of this class of vessel.

    Speaker Name & Bio
    Al McLemore / Retired Department Chair of the Engineering Technology Department @ CMA

    Al McLemore graduated from the California Maritime Academy in 1971 and from there, went on active duty with the Navy for three years, then spent another 27 years in the Navy Reserve retiring with the rank of Captain. Upon leaving active duty, earned a B.S. degree from U.C. Davis in Mechanical Engineering. In 1977, he joined the faculty at CMA. During his 29 year career there, served as the Chief Engineer of the training ship and as Department Chair of the Engineering Technology Department. Upon retirement from CMA, he took the job of Relief Chief Engineer on the Hawaii Superferry, Alakai which was his introduction to aluminum high-speed vessels. This qualified him to become a Chief Engineer for the sea trials of the Austal Shipyard USA built Navy Littoral Combat Ships and the Expeditionary Fast Transports.
