II! Executive Summary The Donner Company manufactures Soldermask over bare copper circuit boards. Meeting specifications of small and large electronic firms by a self-invented process making them one of the industry leaders. The routine process1 can be divided in three main stages - preparation, image transfer and fabrication (Appendix I). In both, image transfer and fabrication, it is possible to choose between two alternate technologies (manual vs. automatic) leading to the same output in a sub-process while differing in a fixed setup time and run time per board. Therefore, a break-even quantity was calculated for both in order to configure a decision rule on which option to schedule customer orders to achieve the smallest total production time (Appendix III). As a result, for manufacturing orders of more or equal than six boards the CNC Drill should be the preferred technology in the drilling process. However, for orders greater...

...supplying a natural gas that burns cleaner than others because of the molecular structure it possess. This supply of natural gas allows the United States to be less contingent on foreign companies for energy supplies and provides royalties for the state of Wyoming. Questar drills and operates in close proximity to wildlife habitats that rely on the mesa, sagebrush and high elevation for survival. The Bureau of Land Management has specific limitations based on the habitat surrounding the drilling sites that Questar must follow to protect the wildlife. Studies were conducted that indicated that the restrictions were not sufficient enough to address the decline in the sage grouse; although Questar have followed the guidelines set forth by the Bureau of Land Management. The sage grouse are being considered for the endangered species list as it is believed to have a population of only 250,000 remaining. The argument that Questar presents is that the federal land was needed for the United States for drilling and mining. To reduce the impact of operations that would affect wildlife, Questar executives prepared a plan to invest in new technology. They petitioned for permits that would allow them to drill for the entire year at a single pad instead of closing down for the winter...

...but by that time, more than 4 million barrels of oil had been released into the gulf. The BP oilrig, owned by Transocean, Deepwater Horizon had been in operation in the Gulf of Mexico since February 2001. The rig was valued at more than $560 million dollars and worked on many different wells in the gulf. The last well it operated on was the Macondo well. It was this well that the oil spill came from and was brought about by several preventable errors on the part of BP and Transocean management and employees. The Deepwater Horizon vessel was an exploratory rig assigned the duty of finding oil, reporting it, and capping the well for another extracting type rig to come in and harvest the oil. While drilling the well, the rig encountered pockets of natural gas buildups where it was drilling. A week prior to the fatal explosion, Horizon encountered one of these pockets and the natural gas began to rise up the drill bore and began surfacing on the rig platform. When this happened, an immediate freeze was put on all activities to prevent an explosion. These same events would eventually play a part in the explosions aboard Horizon. A second major factor was the cementing process. When the well was being prepared for closure so another rig could use it in the future, the team...

...situation? Explain your choice(s). Feedforward control would have been the most useful type of control in this situation. The Deepwater Horizon accident had massive implications for the health of workers and nearby residents, the economy, and the environment. BP had a responsibility to take the potential dangers of their drilling operation seriously and plan for potential problems. There should have been backup protections to prevent accidents like the one that occurred. At the very least they should have practiced concurrent control. At the first signs of a problem they should have taken whatever actions were necessary to prevent the type of disaster that occurred. 2. Using Exhibit 18-2, explain what BP could have done better. First the company needed to measure their actual performance. They needed to look at their practices and analyze the data that they were receiving from engineers on the site to determine whether or not the work was being completed in the proper manner. Once this data was collected it needed to be analyzed in an objective way and compared to both the internal standards and the external regulations set by governing bodies for oil drilling operations. When issues were discovered they needed to be taken seriously by people at all levels of the company and appropriate action needed to be taken to prevent the explosion which endangered both BP employees and residents in the area. Management needed to act quickly and in whatever manner was necessary to prevent...

...information will provide an understanding of rock excavation and the various considerations (i.e. cost, local regulations, safety, etc.) contractor’s should have in mind when estimating and planning projects that involve rock excavation. The Rock Breaking Process When determining the proper method for excavating rock there are a few things you should consider. Determine how much rock you anticipate needs excavating. Is the rock solid? Is the rock easily accessible, how far below grade? Do the aesthetics of the rock matter in the end product? And is there any local regulations restricting particular methods? These are all questions that need to be answered before any rock excavation method begins. The traditional methods are ripping, drilling, breaking and blasting. Blasting is the controlled use of explosives to excavate rock and has been used for many years. When blasting a careful...

...Noble Corporation Project Windmill Can Noble Corporation’s Core Competency in Health, Safety, Environmental & Operational Excellence Be Extended to a Major Acquisition? By Dr. Brooks Holtom McDonough School of Business Georgetown University With Assistance from Michael Amante, Georgetown University Mike Cadigan, Noble Drilling Services Inc. Noble Corporation Noble Corporation’s International Expansion Introduction As Jim Day, the CEO of Noble Corporation for 12 years, looked at the reports before him, he made a list of the many uncertainties inherent in the potential acquisition of Neddrill—the oil and gas drilling services subsidiary of Royal Nedlloyd N.V., a Dutch shipping company. First was the quality of the drilling assets. As far as his people could tell, the rigs would all require significant investment to bring them up to Noble standards. But the exact amount was unknown. Second was the industry’s inability to accurately forecast future dayrates (daily revenue for drilling on behalf of clients) for the rigs. Many insiders expected rates to rise but they had been wrong before with major consequences. Acquiring costly drilling assets could prove very risky if the dayrates went down instead. Third was the complexity introduced by buying a large international firm whose employees were not overly enthusiastic about joining a U.S. based driller. An inability to efficiently integrate the Neddrill assets and people into Noble would reduce the value of the acquisition...

...Theory: Forming process are solid state manufacturing processes involving minimum amount of material wastage and faster production. It does have been one of the common methods in formation of product in multi shape and size. In fact some of casting product will undergoes forming process to achieve more precise shape. In metal forming, transformation to desire shape is done at solid state and usually required high forces. If the temperature is below crystallization temperature, it is called ‘cold work’. Large force is applied such that the material flows and takes the desired shape. These processes are normally used for large scale production rates. It is also generally economical and many cases improve the mechanical properties. Some of the metals forming process are rolling, forging, extrusion, drawing, sheet metal forming and bending. In fabrication of metal dustbin, below process forming process are involved. a. Sheet Metal Cutting -Sheet metal cutting can be done by shearing operation. Shearing is the mechanical cutting of material without the formation of chips or the use of burning or melting. When sheets of metal are to be sheared along a straight line, squaring shears are frequently used. As the upper ram descends, a clamping bar or set of clamping fingers presses the sheet of metal against the machine table to hold firmly in formation. A moving blade then comes down across a fixed blade and shears the metal. On larger shears, the moving blade is often set...

...entrance side and the presence of burrs on the exit side (unless they have been removed). Also, the inside of the hole usually has helical feed marks.[3] Drilling may affect the mechanical properties of the workpiece by creating low residual stresses around the hole opening and a very thin layer of highly stressed and disturbed material on the newly formed surface. This causes the workpiece to become more susceptible to corrosion at the stressed surface. For fluted drill bits, any chips are removed via the flutes. Chips may be long spirals or small flakes, depending on the material, and process parameters.[3] The type of chips formed can be an indicator of the machinability of the material, with long gummy chips reducing machinability. When possible drilled holes should be located perpendicular to the workpiece surface. This minimizes the drill bit's tendency to "walk", that is, to be deflected, which causes the hole to be misplaced. The higher the length-to-diameter ratio of the drill bit, the higher the tendency to walk. The tendency to walk is also preempted in various other ways, which include: * Establishing a centering mark or feature before drilling, such as by: o Casting, molding, or forging a mark into the workpiece o Center punching o Spot drilling (i.e., center drilling) o Spot facing, which is facing a certain area on a rough casting or forging to establish, essentially, an island of precisely known surface in...

Chilean Mining Minister, Laurence Golborne, who had accompanied President, Sebastian Pinera, on a state visit to Quito, Ecuador, got the news at 11pm shortly after their arrival. Golborne informed the president the following morning and flew to Santiago via Peru on commercial flights then took a Chilean Air force flight to Copiapo before a 45-kilometre drive to the mine, arriving on August 7. Golborne, an engineer and entrepreneur, was recruited by the business friendly president who was inaugurated in March 2010 after success as Chief Executive of Censoud A, a large Chilean retail firm. Just 4 months in office with no mining background, Golborne took charge of a widely viewed disaster recovery effort. 69 days later, all 33 miners were rescued. Crew Foreman Luiz Urzua led the 33 trapped miners to form a small society to ration food, preserve morale, and protect their scarce resources. A surface team numbering...
