by 30 meters wide) was particularly delicate. Another innovative feature of the Crown Princess is her propulsion plant. Designed for worldwide cruis- ing, the vessel will be powered by a highly advanced diesel-electric plant. There will be four 6.6KV, 60- Hz main alternators driven through flexible couplings by four MAN B&W eight-cylinder, in-line L58/64 four-stroke, medium-speed engines, with a maximum continuous rating of 9,720 kw at 400 rpm. These alter- nators will supply power through transformers to the two 12,000-kw, three-phase synchronous-type pro- pulsion motors, each directly driv- ing a fixed-pitch Lips propeller via shafting. In addition to supplying 6,600/450 volt, 60 Hz electrical pow- er to the propulsion motors, this same power is fed to the motor-driv- en thrusters and air conditioning compressors, while other motors are generally powered by 440 volts, 60 HZ AC. Other electrical equipment is served by 440/220/115 and 24 volt DC circuits. The construction of the 14-deck Crown Princess involved the forma- tion of a new work organization inside Fincantieri in order to speed coordination and manage construc- tion of the ship. The ship cost about $275 million, 15 percent of which went to the actual construction of the vessel and the other 85 percent towards completing the machinery, furnishings, etc. The work involved over 150 companies and about 10,000 workers, constituting a wide range of suppliers. According to company officials, Fincantieri plans to capture as much as 25 percent of the world cruise ship construction market. Fincantieri has concentrated its cruise ship construction at two yards—the Monfalcone yard and a shipyard located at Marghera. The Regal Princess, sister of the Crown Princess, is expected to be delivered by the Monfalcone yard in April 1991. The yard is then ex- pected to begin construction of the first of three cruise ships for Hol- land America Line. The Marghera yard of Fincan- tieri, located near Venice, has two 55,000-ton cruise ships on order for Italian cruise line Costa Shipping.

September, 1990 Standard Refrigeration Offers Rugged Marine Service Condensers Designed for hostile marine envi- ronments, Standard Refigeration of Melrose Park, 111., is offering marine service condensers in shell and tube and compact tube-in-tube modular counterflow configurations. The shell and tube series is available in 1 to 125 hp models. There are more than 35 cataloged models, plus WR modify condensers with additional valves, brackets, and accessories to meet specific ma- rine applications. All feature cupro- nickel tubes, tubesheets, water plates, and monel fittings for resist- ance to sea water. Marine-duty epoxy coatings are included. The company also incorporated sacrificial zinc anodes to provide protection from stray currents, gal- vanic action, and electrolysis. The MS series also feature dual refriger- ant outlets to maintain constant liq- uid feed, even in heavy seas, and removable water plates to make cleaning easier.
