Algic Record (Continued from Page 14) ord and good condition of the S. S. Axcic is largely due in Mr. Smith’s opinion to her officers. Capt. Afred Ricca has been on this ship prac- tically since she came out. The chief engineer G. M. Gustavson made his first trip as chief engineer on the voyage ending in New York Jan. 2, but Mr. Gustavson served for three years before that on this vessel as first assistant and therefore, has been instrumental in keeping her machin- ery in first-class condition and giving her a rating well over 100 per cent with the shipping board. The S. S. Axeic is a typical three island single screw steamship of 8800 tons deadweight. The propelling ma- chinery furnished by the Westing- house Electric & Mfg. Co. consists of a combined impulse-reaction cross compound turbine of 3000 shaft horse- power at 3360 revolutions per minute with a high pressure and a low pres- sure unit, each of which is con- nected to a first reduction pinion through a flexible shaft and coupling. From this point there is a_ second reduction to the large wheels con- nected to the propeller shaft. The double reduction gear is of Westing- house flexible frame type, the pinions and gears being double. helical with standard involute teeth. Speed at the turbine of 3360 revolutions per minute is reduced to 90 revolutions per minute at the propeller. Lubrication is by gravity. The pinion dips in oil at the bottom of the frame and also receives oil from above. As the pinion revolves it splashes the oil against the gear both where the teeth come into and out of contact. The propeller thrust bear- ing of Kingsbury segmental type is mounted on the main gear shaft _at the forward end of the gear. It is contained in a housing which is solidly fastened to the main gear housing. Steam is supplied by three Babcock & Wilcox water tube boilers of 2900 square feet heating surface’ each, fired with oil burners of Schutte Koerting make. There: is a Foster superheater in each boiler of 200 square feet heating surface and an induced draft system with Sturtevant fan. A complete line of main and auxiliary equipment is fitted as noted in detail in Tables I and II. Again referring to the performance of the S. S. Anaic. The condenser was retubed for the first time in July last year after nearly six years continuous operation. The Babcock & Wilcox water tube boilers have proved particularly dependable and the chief engineer is proud of the fact that not a single tube has had to be renewed in the seven years the vessel has been in operation. An inspection of the tubes in one of the REV IE W March, 1927 carelessness in operation from the bridge does not offset his efforts. The total fuel consumption during her last voyage was 19,283 barrels of oil in- cluding both sea and port and the total distance logged was 22,013 observed miles. On her trip out the Aucic stopped at Philadelphia, Balti- and Norfolk. An analysis of the log for voy- age No. 14, which began on July 10, 1926 and ended Jan. 2, 1927, shows that the weather was moder- ate 78 per cent of the time and rough the remainder. The average speed from revolutions was 10.81 knots and from observation 9.76 knots. Average revolutions per minute of the propel- ler were 81.15. Average fresh water consumption in tons per day was 9.34. Lubricating oil consumption aver- aged 1% gallons per day. Only one grade, that is turbine oil is used. Only three to four barrels of lubricat- ing oil for all purposes are consumed on a 25,000-mile voyage and _ there is still on hand some of the orig- inal oil placed on the vessel when she came out. The lubricating oil is regularly purified by passing through a De Laval oil purifier. Tur- bine oil is used for the line shaft spring bearings with the splash ring system. No trouble of any kind has been experienced) with these bearings. TABLE VII Performance Record—Last Voyage Tabulated of Vessels Listed in Table VI Ay. Obs. Speed served Mile, Knots Ala Bayou Chico City of Weatherford Emergency Aid George Pierce Hastings boilers before and after turbining early in February indicated that they are in fine condition. On her last trip the ALGIC was given a sea rating by the shipping board of 110.9 per cent and a port rating of 86.6 per cent. This is a fine record as the rating of 100 per cent is that set by the fuel conserva- tion section of the shipping board headed by C. J: Jefferson, for a particular ship, after a careful prac- tical study of performance of the class, as that which a capable and conscientious engineer might attain by attention to his duties, always providing weather, the failure of some part of the equipment, or Fuel per Ob- Port Efficiency. Sea Pounds Efficiency 97. , 107.7 NOTE: Reports on the performance of the last two vessels listed in Table VI had not been recorded at the time this table was prepared. The average fuel consumption on the last voyage at sea was 26.02 tons or 172.4 barrels per 24 hours, or 248.7 pounds of fuel oil per ob- served mile. Port stops totaled 85 days and 23 hours and the total port fuel consumption was 2295 barrels or 26.72 barrels per day. A summary of the performance of the S. S. Ancic is given in Table V for six voyages starting with voyage No. 9. The fuel conservation section of the shipping board which now keeps a close check on performance did not begin to function until 1924. From this time records have been kept and tabulated. The voyage figures cover the performance at sea
