IEEE releases standard on vertical generators for hydro plants

IEEE announces availability of a new standard, Guide for the Installation of Vertical Generators and Generator/Motors for Hydroelectric Applications.

This 52-page standard describes the procedures for installation of all types of synchronous generators and generator/motors rated 5 MVa and above to be coupled to hydraulic turbines or hydraulic pump-turbines having vertical shafts.

The Installation of Vertical Hydraulic Turbine Driven Generators/Motors for Hydroelectric Applications Working Group developed the standard.

- The standard can be purchased as a pdf for $100 ($120 non-members) or printed for $120 ($150 non-members) at www.techstreet.com/cgi-bin/detail?vendor_id=4063.

Thordon releases film about oil-to-water lubrication conversion

Industrial parts designer and manufacturer Thordon Bearings Inc. announces the release of a video titled Oil to Water: A Turbine Gets Greener.

The 13-minute video highlights the process of converting a hydro turbine main shaft guide bearing from an oil-lubricated to a water-lubricated system. The company says providing water as an alternative to oil lubrication is a long-standing area of expertise, with its non-metallic bearings having been used in the hydro industry for more than 30 years.

Thordon says it hopes the film will "provide insight into the simplicity of a water lubricated system and its dependability as a green alternative."

"The film aims to raise awareness among energy providers that such a conversion project is not only feasible, but also offers long-term economic benefits," says Scott Groves, Thordon's hydro power development manager and one of the movie's technical advisors.

The video is available at www.thordonbearings.com/clean-power-generation/mainguide/videos.

USSD releases construction cost estimating guidelines

The U.S. Society on Dams offers a white paper, Guidelines for Construction Cost Estimating for Dam Engineers and Owners.

This white paper, prepared by the USSD Committee on Construction and Rehabilitation, provides support for responsible cost estimating for new dams and dam rehabilitation projects. It was written for engineers and owners engaged in the planning, design and construction of dam-related engineering projects anticipated to cost up to $100 million.

Topics addressed include: stages of project design and associated estimates; development of a work breakdown structure; direct and indirect project costs; corporate overhead; contingency; profit; and other owner costs.

The guidance is not intended to serve as a "how-to manual." Rather, the information provided offers a structured reminder of the items that engineers, owners and cost estimating professionals must address when preparing an estimate of expected project costs, USSD says.

- The white paper can be accessed for free at www.ussdams.org/reports.html.

Trelleborg provides mobile apps for hydro professionals

Trelleborg Sealing Solutions has introduced mobile applications designed to help the hydro workforce. In addition to its ISO Fits and Tolerances app, which Hydro Review reported on in July, the company offers an O-Ring Calculator and Unit Hardness Converter.

The apps are designed to provide tools that can be used on the go as the workforce becomes more mobile, says Wolfgang Heinrich, project manager with Trelleborg.

All three free apps are offered in English and German versions. Each of the apps is compatible with Apple iOS and is available for download via the Apple App Store. Trelleborg also offers an android-compatible version of the ISO Fits and Tolerances app via Google Play.

OWA releases best management practices guide for construction

The Ontario Waterpower Association announces availability of Best Management Practices for the Mitigation of Impacts of Waterpower Facility Construction.

This guide was developed to provide practical, current best management practices that will assist in determining how best to construct, rehabilitate or repair a waterpower facility in an environmentally responsible manner, OWA says.

This guide is intended to help environmental planners and engineers during their day-to-day decision making, planning and design activities associated with waterpower construction.

The best management practices have been designed so that they can be easily incorporated into project tender documents. The guide consists of a parent document that provides a summary of each best management practice, as well as 38 individual practices that will be published as an accompanying appendix to the document.

Development of this guide was pursued as a partnership between the hydroelectric industry and the federal and provincial governments, OWA says.

- To order the guide for $49.95 ($59.95 for non-members), visit www.owa.ca/waterpower-information/owa-resources.

Bizier elected vice president-elect of EWRI

Paul A. Bizier, P.E., was elected vice president-elect of the Environmental & Water Resources Institute's Governing Board.

Bizier will serve in a leadership role for the next four years, rotating through the positions of vice president, president-elect, president and past president.

Bizier is vice president of Pape-Dawson Engineers in San Antonio. He is one of two recipients of the 2012 ASCE President's Medal, given to recognize the accomplishments and contributions of engineers to the profession, the American Society of Civil Engineers or the public. EWRI is a civil engineering specialty institute of ASCE.

Book discusses electrical safety regulations

Electrical Safety: A Practical Guide to OSHA and NFPA 70E is now available.

The book, written by James R. White, discusses the interaction between Electrical Safety-Related Work Practices regulations from the Occupational Safety and Health Administration and 70E: Standard for Electrical Safety in the Workplace from the National Fire Protection Association. These documents share a common history, the author says.

White is training director with Shermco Industries, a provider of testing, repair, professional training, maintenance and analysis of rotating apparatus and electrical power distribution systems. He shares real-life incidents through Field Notes so that readers can learn from his experiences and common errors he has witnessed. The book is written as a course textbook with an instructor's guide and workbook also available.

Topics related to OSHA and the 2012 edition of NFPA 70E are presented, including electrical hazards and basic electrical safety, multi-employer worksites, training of workers, approach boundaries for shock and arc flash hazards, performing a hazard/risk analysis, working on energized conductors and circuit parts, portable electric tools and flexible cords, and choosing and inspecting personal protective equipment.

- To purchase this book for $88 and the instructor's guide for $260, visit www.go2atp.com and search for "white."
