A -- DEVELOPMENT OF SIMULATION PROGRAM FOR NAVIGATION STUDIES OF FREEPORT WIGGLES AND HIGH ISLAND, TEXAS SOL DACW39-97-R-0032 DUE 062397 POC Cynthia Sims, Contract Specialist, (601) 634-4317 WEB: Contracting Division Homepage, http://www.wes.army.mil/contract.htm. E-MAIL: Cynthia Sims, simsc@ex1.wes.army.mil. The U.S. Army Engineer Waterways Experiment Station is soliciting sources for the development of simulation program for navigation studies of Freeport Wiggles and High Island, Texas. A "real-time" push tow simulation study shall be conducted to evaluate proposed bend easings. The offeror will supply WES with a methodology, plan, or procedure to use the simulation model as an evaluation tool. The primary objectives of the simulation program are first to evaluate the safety of the proposed bend easings and second to optimize channel layout. Simulation models shall be developed for the existing condition and two proposed channel modifications. The simulator facility must have a pilot- controlled bridge and real-time model of vessel behavior. A visual scene and radar image of the simulation scenarios must be developed and shall provide coverage necessary to include visual cues that lie beyond the limits of the hydrodynamic model. Tidal currents shall be calculated for the existing channel and both plans. The study shall begin with a reconnaissance trip to the Freeport/Galveston, TX area. The existing condition simulation model shall be validated with tow captains experienced in the Freeport Wiggles/High Island area. A formal simulation program shall be conducted with six tow captains. The simulations shall be conducted by a contractor having access to a private simulator. All data files transferred between contractor and WES shall be in ASCII format. All responsible sources may submit a proposal which shall be considered for award. The solicitation will not be provided in hard copy. If you desire a copy of the solicitation, you may obtain a copy by accessing the Internet at http://ebs.wes.army.mil. (0119)
