Balancing the required performance of an engineered solution with its environmental impact is becoming more and more critical. When constructing reinforced soil walls, hard structural facing panels and modular blocks have been the traditional choice for durability. However, the demand for green-friendly infrastructure continues to grow, leading engineers to look for ways to design these walls with vegetated facing.   PYRAWALL® offers an environmentally friendly and economical solution for constructing reinforced-soil walls and steepened slopes. The wrap-face vegetated system consists of PYRAMAT® 75 High Performance Turf Reinforcement Mat (HPTRM) and internal fiber-composite bracing deliver immediate erosion control protection that lasts up to 75 years. The flexibility of the system allows the engineer to incorporate various setbacks and alignments in order to customize the wall or slope to the unique site conditions and geometries.

In this webinar you will learn:
  • To understand the PYRAWALL engineered wrap-face vegetated solution and its applications
  • To gain a basic understanding of the site investigation and geotechnical design approach for this vegetated wall system
  • To become familiar with site preparation and installation of this wall system
  • To understand various methods for vegetating the wall system

Irving, Texas – Fluor Corporation (NYSE: FLR) announced that its joint venture COOEC-Fluor Heavy Industries Co., Ltd. (COOEC-Fluor) fabrication yard has completed the central and wellhead platforms for CNOOC’s Dongfang 13-2 Gas Fields Development Project.

The central platform recently departed the COOEC-Fluor yard in Zhuhai, China, and follows the successful loadout of the wellhead platform in August 2018. The modules will make up part of a new offshore oil and gas production platform in the western South China Sea, 132 kilometers west of Dongfang City.

“This project epitomizes how the COOEC-Fluor team consistently executes with excellence,” said Chris Vertanness, vice president of Fluor and director of operations at the COOEC-Fluor fabrication yard. “More than 2,000 craft workers safely delivered the project on budget and on schedule with extremely high quality and productivity.”

COOEC-Fluor was responsible for assembling, commissioning and loading out the two offshore modules. The two modules have a total weight of 19,100 metric tons, which is equal to about 10,000 passenger cars. The central platform module is larger than a soccer field at 115 meters long, 46 meters wide and 96 meters high.

Safety was at the forefront as the project was completed with 2.3 million work hours without a recordable incident.

The project supports further natural gas development in the South China Sea. Once in operation, the facility is expected to produce 43,400 barrels-of-oil equivalent per day at peak from the high-temperature and high-pressure gas fields.

The COOEC-Fluor fabrication yard is one of the world’s largest fabrication yards at more than 2 million square meters in size. Designed specifically for fabrication, the state-of-the-art yard can accommodate some of the world’s largest modules weighing more than 50,000 metric tons. In addition to module assembly, the yard fabricates more than 7,000 tons of steel and more than 175,000 weld diameter inches of pipe per month.

Washington  – Today, the U.S. Environmental Protection Agency (EPA) issued a broad new rule that strengthens the agency’s ability to rigorously review an expansive list of asbestos products that are no longer on the market before they could be sold again in the United States. This important step closes a 30-year-old loophole that allowed old asbestos uses and products to come back to the market without any reviews or restrictions from EPA. Today’s action gives EPA the authority to prohibit the use of certain products or put in place restrictions to protect public health. This action does not alter the prohibitions made in a 1989 partial ban.

“Prior to this new rule, EPA did not have the ability to prevent or restrict certain asbestos products from being reintroduced into the market,” said EPA Administrator Andrew Wheeler. “This new rule, combined with our ongoing risk evaluations, gives us unprecedented authorities to protect public health from domestic and imported asbestos products and gives us the ability to prohibit asbestos products from entering or reentering the market.”

“Today, we are following the laws Congress gave us to close the door on certain asbestos products to prevent them from returning to the marketplace without EPA’s review,” said EPA Office of Chemical Safety and Pollution Prevention Assistant Administrator Alexandra Dapolito Dunn. “This historic step will add to the protections already in place to prevent the American public from experiencing the adverse health effects of asbestos.”

Today’s action means products like asbestos vinyl floor tiles, insulation, and other building materials, as well as some clothing and manufacturing products containing asbestos, cannot be imported, produced, or sold in the United States before EPA reviews them and puts in place any necessary restrictions, including prohibiting such use. A full list of products covered by today’s rule is available on the agency’s website. Previously banned asbestos items remain banned.

Today’s action complements EPA’s ongoing risk evaluation of a handful of very limited, still ongoing uses in the U.S., which EPA is taking under the Frank R. Lautenberg Chemical Safety for the 21st Safety Act, which amends the Toxic Substances Control Act (TSCA). Addressing limited, ongoing uses of asbestos is one of EPA’s top priorities. The agency is reviewing ongoing uses of asbestos as one of the first 10 chemicals selected for risk evaluation under amended TSCA. The evaluation of the risks associated with ongoing uses of asbestos is required under TSCA section 6. If EPA finds unreasonable risk, the agency will take prompt action to address those risks, which could include restricting or banning other asbestos uses in products. The risk evaluation and subsequent steps will ensure that asbestos uses in products not covered by the 1989 partial ban or today’s final rule are evaluated. EPA is committed to a transparent and open process to finalize the asbestos risk evaluation using sound science on the timetable established by Congress.

The following are part of EPA’s risk evaluation: https://www.epa.gov/asbestos/epa-actions-protect-public-exposure-asbestos#riskevaluation.

Today’s final action takes effect 60 days after publication in the Federal Register. The final rule and supporting documents will be published in the Federal Register and available under docket identification number (ID) EPA-HQ-OPPT-2018-0159 at: https://www.regulations.gov.
