The Wrangell sentinel., 1923-06-28

were greatly interested recently when it was their privilege, to go aboard the first sea-going Diesel electrid vessel ever built.
 The name of this new vessel is Standard Service" It is owned and opratd by the Standard Oil Company of California. Wrangell people were also pleased to find upon the arrival of this new vessel in port that it is commanded by Capt. Clyde Cagle, an old Wrangell boy who grew up here and is we'll known to every one in Wrangell except possibly few new corners.
 A recent issue of Motorship con- tained the following article about this new Diesel-Electric tanker
 For many classes of vessels there can be no question but that Diesel electric drive is exceedingly efficient and economical, particularly for fer ries, fire boats, dredges and canal boats, and now it's use is being ex- tended to new freighters and tank CTS in which it's performance will be watched with much interest. Its ap- plication to a bulk oil carrier has just been carried out by the Stand ard Oil Company of California in their new tanker" Standard Service" :"
 Sea trials of the"Standard Service" were completed off San Francisco on April End, and have been pronounc- ed eminently successful by both the builders and the owners. The nor nal speed of the propeller is 130 r.pm., but during the builders trial it was operated at about 145 reyolu- tions, and the load was less than 1000 amperes, whereas full load rating on the motors is 1,065 am- peres.
 During the owners trial, the craft was we'll loaded. Readings on four different occasions when the control was thrown from :full speed ahead" to full speed astern" showed that at no time did the load go above 1000 amperes. The change from full speed ahead to reverse took from ten to twelve seconds. During the reversal all vibration was eliminat- ed. and unless one were observing g the instruments he would have no indication of what was taking place on the propelling equipment. One of the directors of the Standard Oil Company. who was steering the boat with one hand and operating the controller with the other, Was asked to throw the controller from full speed ahead to full speed astern and was amazed at both the simplicity and perfect control.
 So satisfied were the directors of the Standard oil Company with the results of the trials of the Diesel electric tanker Standard Service that they at once ordered a second pair of 400 b.hp. Pacific-Werkspoor engines and General Electric drive for a duplicate tanker.
 The Standard Service" embodies a number of pioneer steps. The yes- sel is single, compact and self con- tained unit, capable of caring for all her own needs, because she will be able to employ her own cargo-pumps which are electrically operated, whenever she is along side the oil pier, whereas tankers with steam pumps are often required to tank their steam from the shore, no fires being permitted aboard at some ports She is expected to display sev- eral economies through elimination of certain auxiliaries. utilization of electric motor-driven cargo pumps, and employment of electric machin- cry throughout, all of which were made possible by the design of her propulsion machinery. There are two main engines, but only one propeller
