Drilled shafts are high-capacity deep foundation systems, also known as drilled piers, caissons, bored piles, or cast-in-drilled-hole piles (CIDH). Drilled shafts for structural support can be installed by the dry (open hole), stabilizing polymer slurry, or steel-cased methods.
[pdf] Factories and workshops located in areas with a lot of dust use filter housings to keep stabilizing compressors. The housing filters out the fine dust before it gets to the air tools or piping system. This application extends the life of air-driven machines and equipment.
[pdf] Deepwater Horizon was an ultra-deepwater, dynamically positioned, semi-submersible offshore drilling rig owned by Transocean and operated by the BP company. On 20 April 2010, while drilling in the Gulf of Mexico at the Macondo Prospect, a blowout caused an explosion on the rig that killed 11 crewmen and ignited a fireball visible from 40 miles (64 km) away. The fire was inextinguisha. DesignDeepwater Horizon was a fifth-generation, RBS-8D design (i.e. model type), deepwater, , column-stabilized, semi-submersible , designed to drill wells for oil explorati. .
Deepwater Horizon was built for R&B Falcon (which later became part of ) by in , South Korea. Construction started in December 1998, the was laid on 21 March 200.
