Jane Barrow, CEO of Caprica Energy, must recommend to the board which of three potential “unconventional ” natural-gas development sites in different parts of the United States the company should pursue. The case takes place in January 2011, when the “low-hanging fruit ” of natural-gas production in the United States had essentially been picked. All three of the potential sites (shale, coalbed methane, and tight sands) would require hydraulic fracturing, a process of removing gas that was formerly considered inaccessible by injecting water and chemicals into the ground. Because of emerging concerns about the potential harm “fracking ” can do to drinking water, Barrow must not only analyze which site might be most profitable but also what the potential risks to the environment and area residents might be.

The Royal Danish Navy frigate Peder Skram successfully passed her sea trials on March 15–19, 1966, and has been in operation for about nine months, with an accumulated gas turbine operation of 490 hr at the end of December 1966. The frigate has twin-screw CODOG propulsion machinery consisting of a 22,000-shp jet-engine-fed power turbine and a 2400-shp two-stroke diesel engine. These two alternative prime movers drive the propeller shafts with controllable-pitch propellers through a common reduction gear including freewheeling clutches. The control system is described, embracing the governor system, the maneuvering system, and the instrumentation and safety systems. Operational experience at sea, including parts of the trials, is described, as well as experience gained by the Royal Danish Navy, including the voyage made by the frigate to the United States in October–December 1966.
