This book was released on 2000 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a 2-D depth-averaged numerical model simulating water flow and reactive contaminant and sediment transport in bay/estuary systems. This model includes two computational modules: flow and transport. We use a splitting strategy to solve hydrodynamic equations where the method of characteristics (MOC) is employed first to compute circulation without taking into account eddy fluxes, and then the Galerkin finite element method is applied to deal with eddy fluxes. The computed flow results are used to compute the migration of sediments and contaminants in the transport module. Sediments can be either suspended in the water column or deposited on bed rock, and whose distributions are determined subject to advection, dispersion, and deposition/erosion processes. Contaminants, either organic or inorganic, may exist in the dissolved phase in the water column or in the interstitial water of the bed sediments. They may appear also as particulate chemicals on sediments through adsorption reactions. All chemical reactions, including aqueous complexation, adsorption/desorption, and volatilization, are assumed elementary and kinetic with reaction rates calculated based on the collision theory where forward and backward rate constants are determined experimentally. We employ a predictor-corrector strategy in the transport module where transport equations are computed in the predictor step with reaction rates estimated at the previous time, and rate correction is achieved node in the corrector step to obtain the concentration distributions at the present time. The Lagrangian-Eulerian approach is applied to solve the transport equations in the predictor step with a particle tracking technique used to handle advection. The Picard method and the Newton-Raphson method are used to solve the rate correction equations for sediment distribution and reactive chemistry, respectively, in the corrector step. Four examples are used to demonstrate the capability of this model.

Available in PDF, EPUB and Kindle. Book excerpt: A unique software application has been developed which combines a set of three modeling programs under one user interface to allow shipyard environmental managers to perform technical environmental modeling and risk evaluation in preparation for NPDES discussions with their regulators. This suite of programs 1.) takes simple shipyard data such as slopes, areas, copper concentrations, sediment load and rainfall data, and 2.) calculates the dispersion of the copper throughout a body of water and its sediment, and then 3.) estimates the risk involved to specified aquatic organisms from the predicted pollutant levels. The models, as packaged herein, were developed using NASSCO shipyard as the test or base shipyard. Thus, the bay modeled is the San Diego Bay and the discharge source is NASSCO's location on the bay. In addition, copper is the only pollutant considered in the model; it was selected as being one of the most toxic and difficult contaminants to control. Using the current version of the application, any facility located on San Diego Bay can easily modify the discharge location and begin to use the models. For facilities outside of San Diego Bay, additional programming will be needed to incorporate the specific tidal and bathymetry data for their own water body before the application can be used for their facility. Additional organisms can be added to the ecological risk evaluation at anytime, provided that copper toxicology data is available for the organism. A survey of regulatory agencies indicated that slightly over half of the 23 survey respondents would allow an industry to renegotiate its NPDES permit limits based upon an ecological risk assessment of the facility's discharge, although not all are currently doing so. Some respondents thought it would be 2-10 years before they are ready to do so. One regulator said that ecological risk assessment will never be used by their agency for NPDES permitting.

This book was released on 1998 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Newport News Shipbuilding was contracted by the National Shipbuilding Research Program (NSRP) to develop a model contractor health and safety program for shipyards. During this project several documents were prepared in a format which would facilitate safety and health management of contractor activities at shipyards. The elements of a good contractor health and safety management program include management support for the program, a procedure for selection and evaluation of contractors, orientation of contractor personnel to the shipyard, methods for monitoring contractor performance, and overall evaluation of the program. This report provides sample documents that incorporate these elements in a comprehensive program. Shipyards may use these materials as templates to assist them in developing and implementing their own contractor health and safety programs.

This book was released on 1995 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air quality issues have gained much importance due to the promulgation of federal regulations such as the 1990 Clean Air Act Amendments (CAAA). As environmental regulations increase in rigidity and become more expansive, industry must continually evaluate their operations and focus on the potential for proactive pollution prevention. lndustry has the greatest understanding of their processes, practices, and organization therefore, industry itself is best suited for determining cost effective methods for controlling air pollution. Industry realizes that it should take a proactive approach to reduce air pollution because of the importance of minimizing air pollution and reducing industrial impact on the environment and public health. In many cases, Air Quality Best Management Practices (AQBMPs) are the most effective mechanism to minimize air pollution from shipbuilding and repair operations. For the purpose of this project, the NSRP defines AQBMPs as low cost, low technology, common sense measures and practices designed to reduce air pollution. AQBMPs are frequently the most cost effective method of pollution control and therefore, an area of research that the NSRP directed project finding. The goal of this project was to investigate shipyard operations and develop AQBMP ideas to be presented in a resource document. The resource document provides environmental and production personnel with suggestions for minimizing emissions from several production operations and equipment. The AQBMPs are designed to be flexible to be customized for a specific shipyard. A suggested AQBMP implementation strategy is also provided in the document for additional guidance. Developing and implementing proactive AQBMPs will benefit shipyards and enhance their current environmental management efforts.

Book excerpt: This document represents Avondale shipyards Long Range Facility Plan. The plan is, in part, a response to an industry priority set forth by the Merchant Marine Act of 1970: to improve shipbuilding productivity and reduce shipbuilding while maintaining requisite high standards for critical processes and operations. This long range facility plan is an integral part of dale Shipyards' Ishikawasima-Harmima Heavy Industries costs pro- Avon- (IHI) Technology Implementation Program. The primary objectives are to decrease the time between the contract date and ship delivery and to increase productivity and reduce cost. The purpose of Avondale Shipyards' Long Range Facility the overall parameters for the growth and the Main and Westwego Yards looking as far Plan is to establish development of both as is practical into the future. Through this effort, development patterns can be established within which succeeding growth phases can be planned.

This book was released on 1997 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Water Pollution Control Act, amended by the Clean Water Act of 1977, was adopted in order to restore and maintain the chemical, physical, and biological integrity of the Nation's waters. To achieve these objectives, the National Pollutant Discharge Elimination System (NPDES) was developed and implemented. The NPDES program established limitations on wastewater, storm water and other water discharges from industrial operations. Shipbuilding is considered an industrial activity thus, discharges of water associated with shipbuilding are required to conform to the requirements of the Clean Water Act (CWA). Shipyard process areas most commonly affected by the CWA are drydocks, graving docks, painting facilities, railways, and maintenance facilities.

This book was released on 1976 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ship Production Committee is made up of representatives from approximately twenty-four shipbuilders plus the American Bureau of Shipping, U.S. Coast Guard, U.S. Navy Research and Development and, of course, the Maritime Administration whose budget is the backbone of this vital project. We poll the industries to see who would use the results of a research project. The more yards that would use, the higher the priority; the higher the potential saving, the higher the priority. We then list the projects in priority sequence, see how far the budget reaches for the year, and submit those to the Maritime Administration for approval. When approved and a shipyard agrees to act as sponsor, a suggested contract is worked out between the sponsor shipyard and the Maritime Administration. The most valuable result of this program is that the shipyards are talking to each other at the working level for the betterment of our industry.

Available in PDF, EPUB and Kindle. Book excerpt: This project was sponsored by the Special Testing and Studies Committee ("Ad-Hoc") of the Environmental Technical Panel ("SP-1") to provide initial funding to develop an ongoing cooperative dialogue with senior national regional and state environmental agency personnel. The goal of this project is to provide the means to facilitate this dialogue in the most cost-effective manner. A secondary goal of this project is to provide the shipyards with a significant resource on technical environmental issues of concern. After approval off this project's original proposal the members of the Ad-Hoc committee requested that this project's scope of work be modified to more closely align itself with the U.S. Environmental Protection Agency's Sustainable Industry Program's US Shipbuilding and Repair Industry Section project. This was accomplished by reformatting this project's Task Deliverables to correspond with the EPA's Sustainable Industry project goals. Additionally the EPA provided funding to expand the overall scope of the work to include specific Sustainable Industry project deliverables. This portion of the overall NSRP/EPA-SI project now consists to two Task Deliverables: I. Development of a comprehensive US Shipbuilding and Repair Industry Sector contact database: and 2. Performance and analysis of a Shipyard Environmental Issues of Concern survey. This report documents the results of these two tasks. Additional reports will be prepared and provide to the NSRP regarding the results of additional Tasks funded by the EPA-SI and other sources. The final collection of these reports will be considered to be the Final Project Report for both the NARP and EPA-SI.

This book was released on 1998 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1991, the National Shipbuilding Research Program (NSRP) approved a project with the original intent of transferring the parameters of the Steel Structures Painting Council (SSPC) Painting Contractor Certification Program (PCCP) to U. S. Shipyards. The PCCP included requirements for quality improvement and quality assurance throughout a contracting organization, such as a third party invited by a shipyard to conduct work in ship repair or maintenance activities. Following extensive review of the purpose and content of the project by the National Shipbuilding Research Program SP3 Panel volunteer group, the direction of the project was altered. The feeling of the review group was that an effort which embodied the quality components of the original PCCP program. decoupled from the external review and certification aspects, was appropriate. As the primary products of this research project. SSPC developed Quality Program Training Modules. These training modules were designed for use at shipyards that rarely employ external contractors and offer training and skill improvement to both trainers and Deckplate personnel. SSPC. in conjunction with Bath Iron Works (BIW) and representatives of the United States Navy's Inspector Group. conducted a series of training sessions offering the substance of this Quality Program to both Deckplate and managerial personnel.
