Book Description
The Houston/Galveston Navigation Channels are located along the Gulf of Mexico Coast in eastern Texas. These channels include the Entrance Channel, the Bar Channels (Bolivar Roads Area), Galveston Channel, the Texas City Channel, the Gulf Intracoastal Waterway (GIWW), and the Houston Ship Channel (HSC) which branches off the Bolivar Roads Channel, traverses Galveston Bay, and ends in Houston. The intersection of the HSC and GIWW is a navigation concern because of the high volume of towboat and ship traffic in the area. Tows turning from the GIWW into the HSC block the ship lanes while making the turn toward Houston. A navigation study was conducted for this intersection, including a real-time ship simulation of the project area, to determine a cost-effective channel design for safe navigation. Considerations in designing the turn include: strong currents, ship-to-tow interactions, bank effects, and channel marking. Hydrodynamic modeling of Galveston Bay was a key element of the study and provided currents for the navigation design. Deep-draft navigation, Houston, Galveston, Navigation channels, Gulf Intracoastal Waterway, Ship simulation.

Book Description
The Houston/Galveston Navigation Channels are located along the Gulf of Mexico Coast in eastern Texas. These channels include the Entrance Channel, the Bar Channels (Bolivar Roads Area), Galveston Channel, the Texas City Channel, the Gulf Intercoastal Waterway (GIWW), and the Houston Ship Channel (HSC), which branches off the Bolivar Roads Channel, traverses Galveston Bay, and ends in Houston. The HSC consists of approximately 65 miles of improved deep-draft channels. The present channel is 400 ft wide and 40 ft deep at mean low tide for most of the channel distance. The project design calls for the channel to be improved in two phases. The Phase I channel is to be 530 ft wide and 45 ft deep, and the Phase 2 channel is to be 600 ft wide and 50 ft deep. A navigation study was conducted for the Houston/Galveston Navigation Channels, including a real-time ship simulation of the project area, to determine a cost- effective channel design for safe navigation. The Texas City Channel and the section of the HSC past Boggy Bayou are not included in the improvement project. The HSC is designed for two-way deep-draft traffic. The capability of large loaded vessels to meet and pass is the primary factor in determining safe channel width. In the highly restricted channel, both bank and ship interaction effects are significant factor in conducting bow-on meeting and passing maneuvers.

Book Description
The Houston/Galveston Navigation Channels are located along the Gulf of Mexico Coast in eastern Texas. These channels include the Entrance Channels, the Bar Channels (Bolivar Roads Area), Galveston Ship Channel, Texas City Channel, the Gulf Intercostal Waterway (GIWW), and the Houston Ship Channel (HSC), which branches off the Bolivar Roads Channel, traverses Galveston Bay, and ends in Houston. The existing Entrance Channels are 42 ft deep and 800 ft wide. Phase I and Phase II of a proposed improvement project will deepen them to 47 ft and 52 ft, respectively. The Phase I and II Entrance Channels will be extended into the Gulf of Mexico to naturally deep water. The Galveston Ship Channel is presently 40 ft deep and 1,100 ft wide. Phases I and II of the proposed improvements will deepen the channel to 45 and 50 ft, respectively, while decreasing the width to 450 and 550 ft, respectively. The U.S. Army Engineer Waterways Experiment Station conducted a navigation study to evaluate the effects of the proposed improvements on navigation. This study was conducted at WES using a real-time ship simulator. Deep-draft navigation, Ship simulation.

Book Description
A ship computer simulation study for Houston-Galveston Navigation Channels, TX, is performed. The study includes existing conditions and two proposed channel widths. The primary design question is related to ships meeting and passing in the narrow channels. Recommendations are made concerning channel width. Houston-Galveston Navigation Channels, Ship navigation simulation, Ships meeting and passing.
