Marine Computers '91 To Be Held In Boston, September 26-27 The New England Section of the Society of Naval Architects and Marine Engineers (SNAME) will hold Marine Computers '91, the sec- ond symposium on computer appli- cations in the marine industry, at the Boston Marriott, Burlington, Mass., on September 26 and 27. The symposium will be divided into four sessions, with two pre- sented each day. On September 26, in the "Analysis and Design" ses- sion, papers covering such items as design optimization techniques, propulsor design, computerization of stability tasks and practical in- teraction among commercial marine design software packages will be presented. On the same day, in the "Shipboard Applications" session, papers will cover the use of com- puter technology for machinery monitoring and diagnostics, bridge automation, graphical user inter- faces, navigation optimization and on board training. On September 27, the first ses- sion will focus on CAD/CAM, with papers covering artificial intelli- gence applications in ship design and construction, shipbuilding project management applications and geometric modeling.

Ferry Conversion Nears Completion At Marine Hydraulics At the Port of Norfolk, Va., Ma- rine Hydraulics International, Inc., is in the final stages of completing a conversion package on the ferry Vir- ginia for the Commonwealth of Vir- ginia. The conversion package in- cludes: complete electrical repower- ing from DC to AC, fabrication and installation of two pilothouses and salon, and complete renewal of both car and salon decks. To accomplish all underwater re- ¥airs to the vessel, MHI utilized idewater Construction Corp.'s floating heavylift derrick Samson to lift the 300-ton ferry from its pierside berth to a repair berth prepared on land. Recent projects at Marine Hy- draulics International include the lay-up preparation of the converted T-2 SS Washington for American Foreign Shipping Co. Inc., for her return to RRF status, installation of vapor recovery systems on two tank barges, and a number of U.S. Gov- ernment contracts. One noteworthy project involved post-delivery repairs and modifica- tions on board the Navy Aegis de- stroyer USS Arleigh Burke (DDG- 51) for Bath Iron Works. Marine Hydraulics International has pro- vided this service and support for BIW during the last several years on an exclusive basis for all types of vessels constructed by the Maine shipbuilder. Marine Hydraulics International maintains full service repair facili- ties with pier capacities of up to 600 feet in length with water depths to 27 feet at mean low water.

Fairhaven, MA. Circle 303 on Reader Service Card engines equipped with electronic mufflers has been announced by Noise Cancellation Technologies, Inc. (NCTI) and De- troit Diesel Corporation. The agreement culminates a two- year informal relationship between NCTI, an innovator in active noise reduction systems, and Detroit Die- sel, a leading heavy-duty diesel engine manufacturer. According to the agreement, the two companies will demonstrate NCTI's active noise control technol- ogy on Detroit Diesel engines in field tests of various applications. 20 Maritime Reporter/Engineering News
