Machinery
Polar Sea uses four different methods of electronic navigation to overcome the difficulties of high-latitude operations, and a computerized propulsion control system to effectively manage six diesel-powered propulsion generators, three diesel-powered ship's service generators, three propulsion gas turbines, and other equipment vital to the operation of the ship. The extensive use of automation and low maintenance materials have greatly reduced staffing requirements.
Polar Sea's three shafts are each turned by either a two diesel-electric or one gas turbine power plants. Each shaft is connected to a 16-foot (4.9-m) diameter, four-bladed, controllable-pitch propeller. For all three shafts, the diesel-electric plants can produce a total of 18,000 shaft horsepower (13,425 kilowatts) and the gas turbine plants a total of 75,000 demand shaft horsepower (56 MW) or 60,000 continuous horsepower (44.8 MW).

Famous quotes containing the word machinery:
“Man will never be enslaved by machinery if the man tending the machine be paid enough.”
—Karel Capek (1890–1938)
“A fine-looking mill, but no machinery inside.”
—Hawaiian saying no. 1702, ‘lelo No’Eau, collected, translated, and annotated by Mary Kawena Pukui, Bishop Museum Press, Hawaii (1983)
“Every Age has its own peculiar faith.... Any attempt to translate into facts the mission of one Age with the machinery of another, can only end in an indefinite series of abortive efforts. Defeated by the utter want of proportion between the means and the end, such attempts might produce martyrs, but never lead to victory.”
—Giuseppe Mazzini (1805–1872)
