SNAME Gulf Section Meets In Biloxi

The Gulf Section of The Society of Nava' Architects and Marine Engineers (SNAME) held its fall meeting at the Biloxi Hilton in Biloxi, Miss. Two informative and interesting papers were presented.

John F. Robbins II of Ingalls Shipbuilding presented a paper describing a "Destroyer Synthesis Computer Algorithm." This gorithm is an effective tool in establishing a baseline weight estimate during the feasibility or conceptual design process for a ship utilizing a destroyer hull form. Inputs for this model include payload, performance and mission requirements, manning, and a description of vessel characteristics. Outputs include estimates of speed and power, electrical load requirements, fuel load, total volume, weights by weight group and vertical centers of gravity.

The development of submerged foil hydrofoils with emphasis on the "Boeing Offshore Jetfoil" was the topic of the second paper, which was delivered by Robert Woodruff of Boeing Marine Systems. Boeing hydrofoils, which have been under development for over 25 years, have three major systems that make them unique—fully submerged foils, water jet propulsion, and an automatic foil control system.

With its high speed and superior seakeeping ability, the jetfoil promises to find a sizable role in the support of the offshore oil industry. Boeing engineers are currently working to complete development of a personnel transfer device needed before the jetfoil can assume this role.

Dr. John Hackett, vice chairman-East, and Chet Hard, papers chairman, presented certificates of application to the authors for their papers.
