- World War II-Era Chapel Move Highlights 'Green' Sustainability
How do you go about moving an 87-ton chapel built during World War II? Ask experts at the
Army Corps of Engineers' Seattle District. The movement of an old chapel located at Fort Lewis
Army base in Washington presented unique challenges, detailed in this article. Moreover, the
project spurred a huge effort to reincarnate the chapel as an education center near DuPont,
Washington. In re-using the building, the Corps of Engineers is using sustainable construction
products that are more corrosion resistant, energy efficient, and environmentally friendly. The
DoD Corrosion Office provided funding to the Corps' Construction Engineering Research Lab
(CERL) to complete the project.
- NASA Engineers Evaluate Innovative Technique to Detect Hidden Corrosion
Since safety is a high priority for NASA, the proper operation and maintenance of every system
is highly important. Before the Space Shuttle launches and after it lands, NASA's experts must
carefully inspect its thermal protection tiles. The thermal protection system is one of the
linchpins in the Shuttle's capacity to travel in space. The system allows the Shuttle to withstand
thermal cycles in space and return home through extremely high temperatures of the Earth's
atmosphere. This article explores the challenges facing NASA's corrosion inspectors who
scrutinize areas underneath thermal protection tiles.
- Remote Imaging System Streamlines Analysis of Tank Coatings on Ships
As part of its scientific and technology research for the Navy and Marine Corps, the Naval Research Laboratory (NRL) is working hard to reduce the cost of corrosion on sea vessels. In one notable effort, the NRL aims to inspect and maintain thousands of shipboard ballast tanks annually. This article reviews a new program that analyzes the condition of tank coatings on ships without the need for a human inspector.
- Army Receives Patent for a New Self-Healing Coating
This year the U.S. government has awarded a patent to the Army Corps of Engineers for a self-
healing coating technology pioneered by several corrosion experts. There is widespread use for
the coating on cars, bridges, oil rigs and platforms, and other steel structures. In this article, two
specialists at the Corps' Construction Engineering Research Laboratory discuss the self-healing
coating, its uses, and a related patent that should be awarded in 2008.
