T his paper anticipates a future need for welding processes in depths to 5000 meters. Arc cutting and joining processes are found to be the most suitable for depths in excess of 1500 meters because they avoid the problem of gas liquification. The underwater arcs are enhanced by constricting effects produced by the deep ocean environment, and no problem with heat generation is expected. Argon or nitrogen shielded arcs are advised for deep sea work. Their use can lead to reduced power requirements, control of penetration and metal transfer rate, and a reduction in porosity and slag inclusions. The cumbersome diving dress required to offset the cold and the problem of visibility in bottom waters is expected to produce the most serious operating difficulties for the welders. Cryogenic gas transport and experimentation in the laboratory and at sea are recommended.

HANSEN, O. RICHARDUHLER, DALE G.O. Richard Hansen obtained a BSCE from Colorado State University in 1950 and has participated in continuing educational courses at the University of Washington
Wayne State University and the University of Michigan. He was employed at Puget Sound Naval Shipyard for five years as a Mechanical Engineer and Project leader in industrial gases and cryogenic O2. Producers for Shipboard Applications followed by seven years at Chrysler Corporation initially as a project engineer in the FBM program subsequently assigned to Mechanical Laboratory achieving Managing Engineer status of a department therein which contained the facilities group instrumentation group and an experimental machine shop. This was followed by employment at Westinghouse Astronuclear Laboratories as a senior engineer conducting studies in two phase liquid hydrogen flow in simulated NERVA cores. Following this he served two years of employment with the Lockheed Georgia Company conducting material studies in combined nuclear cryogenic environments at the NASA 60 megawatt test reactor located in Sandusky Ohio. Joined NAVSEC in 1966 as a mechanical engineer in the compressed air systems group and has been assigned to the Supervisor of Diving Salvage and Ocean Engineering conducting analysis and evaluation of compressed air and gas systems associated with diving and salvage operations. Dale G. Uhler received BSCE degree from Carnegie Institute of Technology in 1964. He spent two years as a construction engineer before entering graduate school at the University of Miami
Florida where he received his MS degree in applied mechanics with a minor in Ocean Engineering in 1968. He is now employed as an Ocean Engineer in the office of the U. S. Navy Director of Diving Salvage and Ocean Engineering where he is the project manager for the Large Object Salvage System and related development programs and concurrently working toward his Ph. D. at Catholic University.
The advent of deep oceantechnology has created a need of buoyancy at ever increasing depths. This paper concerns itself with two most widely used techniques for dewatering/deballasting, compressed air supplied by sur...

RAWAT, Pwho began his education in his native India
received a Bachelor of Technology degree with honors from the Indian Institute of Technology in 1957. His subsequent education includes S. M.‘s in Industrial Management and Naval Architecture & Marine Engineering from M. I. T. in 1961 and a professional degree in Naval Architecture from the same institution in 1965. Rawat's career began as a Naval Architect in preliminary design with the Hamburg firm of Howladtswerke in 1958. A year later he performed as a research assistant in M. I. T.'s School of Industrial Management for a Ford Foundation Project for a top management training program for India. After this two-year period he acted as the head of the Department Head of Engineering at the Ghana Nautical College in West Africa until 1963. He returned to M. I. T. afterwards to work as a research assistant in Naval Architecture on structural optimization programs. From 1965 to 1966 he filled the capacity of Naval Architecture with M. Rosenblatt & Son in the area of structural design on such projects as MOHOLE AGOR 14 and Catamaran Hull. Since 1966 Rawat has been working in various capacities with Litton Industries: Senior Naval Architect on the FDL Project Section Manager of Hull Structures for the LHA and DD Projects
and his present position as Section Manager for Computer Aided Ship Design.

Many useful conclusions can be drawn if hull structural design is considered as a system. Proper definition of system objectives enables setting up of meaningful long range and intermediate goals. Current state-of-art in systems engineering is such that the system objectives can be denned in mathematical form. This provides meaningful scales for progress measurement. The engineering function is to meet the goals set by systems engineering. The state-of-art in engineering has a considerable impact on the definition of system objectives. In recent times we have made considerable progress in developing analytical techniques. Many interesting conclusions result from our experience in using the analytical tools in an iterative manner for design. By using relatively simple algorithms for iteration the analytical processes can be sequenced in such a manner that optimum solution is guaranteed even under a large and complex set of design constraints. Use of computers makes it possible to generate the scantlings using iterative approach with such speed that many important structural configuration decisions can be made by means of thorough parametric analyses. The system objectives therefore are very different in scope today and they should be further modified as technology advances. There are several problems that can be recognized and solved in the systems context. Smooth man-machine operation is an example of this.

WOSSER, J.L.The author is program manager for all air cushion vehicle (ACV) projects of Textron's Bell Aerosystems Company
Buffalo New York. A veteran of 20 years in the U. S. Marine Corps Wosser retired in 1963 with the rank of Lieutenant Colonel. Since September 1958 Wosser has served as head of the Air Vehicle Design Branch of the Office of Naval Research in Washington D.C. In this post he was responsible for planning coordinating managing and providing technical supervision of a multi-million dollar contractor program of research and exploratory development. These programs included research in vertical/short takeoff and landing test vehicles and air cushion vehicles. Wosser authored some of the first technical papers on air cushion vehicles published in the United States beginning in 1958 when ACVs were in their infancy. Currently he is active in the administration of the several ACV projects conducted by Bell. Included are: the U. S. Navy's SKMR-1 Hydroskimmer and Bell/Westland SR.N5 air cushion vehicle test and mission suitability trials now going on at the U. S. Navy's Norfolk Va. base preparations for the first year-round ACV scheduled passenger service set to begin this summer in the San Francisco-Oakland areaand two hydrokeel military amphibious assault projects. A native of Mill Valley
Calif. Wosser became a Naval aviation cadet in 1943 after studying mechanical engineering at the University of California. During his 20 years as a Marine pilot Wosser accumulated 3600 hours of flight time including 350 combat hours. He holds a master of science degree in aeronautical engineering from Massachusetts Institute of Technology and bachelor of science degrees in military science and aeronautical engineering respectively from the University of Maryland and the U. S. Navy Postgraduate School.
