MICH. 49721 TOPICS OF SPECIAL INTEREST EXPERIENCE UOA has specialized in the design of harbors, marinas, and waterfront work, coastal engineering and related fields since it was first organized in 1955. The company has actually designed In excess of 300 waterfront projects during its history as a consulting company. COMPUTER MODELING UOA has developed extensive ccmputer modeling programs of wave analysis utilizing the Corps of Engineers research data, the latest THA spectrum, and Goda's update for random seas and of maritime structures. As part of this program methodology UDA also has the capability of developing and drawing with the AUTOCAD system the numerical models of the diffraction diagrams and the refraction diagrams generated by the approaching waves analysis. KELVIN FUNCTIONS UDA has programmed the Kelvin functions in conjunction with the Kerr-Nevel equation which permits the rapid computer analysis of vertical ire forces on piles and structures for any variable ice property that may be selected, this same program is applicable for the computer analysis of ice loading potential for any selected load that could be placed on an ice plate. UOA has over the years done insitu ice load measurements and confirmed the accuracy of the theoretical ice forces developed by the Kerr-Nevel equation. ICE PILE SOIL RESEARCH UDA has actively cnegaged in testing various theories with respect to the ice-pile-soil resistance capability for various soil conditions and various ice thicknesses. CAOO SYSTEM UDA is state-of-the-art with the AUTOCAD system utilizing the latest technology in preparing drawings with disk storage capability which permits rapid modifications at very low cost, and also permits rapid retrieval for subsequent drawing reviews. UDA also utilizes the compact disk system (CDROM) for orage of specifications and product data. TOTAL ELECTRONIC STATION UDA utilizes a total elertronic station which permits field observation of wave heights, soundings, and topographic survey data that can be recorded and transcribed through the computer to the printer. FLOATING BREAKWATER RESEARCH UOA is conducting research and development with Allen Dock Manufacturing of Florence, Wisconsin for constructing a floating breakwater. This type of project is of special Interest to the Fish & Wildlife Service for areas of smaller wave intensity that will ultimately replace the need for such a structure to physically occupy the bottomland and interfere with fish migration and habitat. Floating breakwaters also have the potential of easily being moved for location adjustment of the protected facilities. A proto-type is being constructed for testing under various conditions. The most important use of a floating breakwater may be its use as a secondary breakwater which could permit a much lower cost rubblemound breakwater as the outer or initial wave interceptor. __ _i.
