Now comes the latest addition in the in- troduction of the diesel propelled car- ferry Korsor with three sets of rails with a total length in effective track- age of 787 feet. Each of the ferries on the route make ten to twelve trips daily at about 1% hours’ duration which means about eighteen hours at sea in a continuous twenty-four hour serv- ice. The 70 per cent increase in available length of rails for accom- modating cars was made possible in the Korsor, which on account of the old jetties is built to practically the same dimensions as existing ferries, by the adoption of diesel engine drive. It is also plain that the operating ex- penses will be less than for smaller capacity steam ferries, that the new vessel will be cleaner, and that it is immediately ready at all times to put to sea without the necessity of main- taining banked fires. Passengers, it is claimed, are much better off on 24 the Korsor as all accommodations are more spacious, amounting to 25 per cent with the slightly increased dimensions. The Korsor is 315 feet in length and 58 feet in breadth amidship’s over fenders; the depth is 20 feet 3 inches and the draft is 13 feet 1 inch. The hull is built of steel to the rules of the Bureau Veritas with a flush main deck carrying three sets of tracks recessed into the wooden deck in order to make it smooth going for automobiles which are also being car- ried in addition to railway cars and passengers. Roomy accommodations are fitted on the lower deck fore and aft of the engine room. Above the main deck is a promenade deck 197 feet long cover- ing the full width of the vessel. A certificate has been given the Korsor to carry a car. load of of 500 tons and 1500 passengers. The running speed is 15% knots. The propelling machinery consists MARINE REVIEw—July, 1927 SECTION THROUGH ENGINE ROOM of two, 8 cylinder, 4 cycle, single acting, force lubricated, direct revers- ible, trunk piston, diesel engines of special ferry type built by Burmeister and Wain. The two engines in the KoRSOR were designed as starboard and port engines with valve and man- euvering gear facing. The two en- gines together developed 4000 indi- cated horsepower at 180 revolutions per minute. They are fitted with gov- ernors of B. & W. type so that they can run evenly at 45 revolutions per minute. These engines have been very carefully built and the design is in- tended to give maximum strength. Cylinders are fitted with separate cooling water jackets. Cast steel levers actuate the valves. The cam _ shaft which actuates the valve levers may be moved longitudinally, while turning, for ahead or astern position. The re- versing gear is worked by compressed air used in a rotating gear motor with an oil brake. Each main engine is fitted with an air compressor of the three stage type bolted to the forward end and worked directly from a crank. Auxiliary Machinery Two, three-cylinder 150 brake horse- power Burmeister & Wain diesel en- gines running at 400 revolutions per minute are installed each driving a 100-kilowatt dynamo. There is also one three cylinder 75 brake horsepower diesel engine of B. & W. type run- ning at 500 revolutions per minute directly coupled to a 50-kilowatt dy- namo. Each of the above generating sets are also directly coupled to a compressor of the three stage type of B. & W. patented design which al- lows the output to be automatically adjusted to meet the demand.
