Cut Costs by Conserving Fuel Application of Fuel Conservation and Engineering Performance Standards to Shipping Board Vessels N CONNECTION with this paper, reference should be made to a paper presented in November, 1923, which describes the methods by which these standards have been de- veloped. In order to put these stand- ards to practical use, it was neces- sary first of all to establish a sys- tematic inspection of the active ves- sels of the fleet and their perform- ance. From a continuous record of these performances it is determined whether improvements in operation are being obtained on the vessels, and what effect modifications made in. the equipment of these vessels have on their performance. Fortunately a nucleus of such type of inspection had already been created, and it was only necessary to extend the scope of its work and to draw up an inspection report form giving the chief items which will af- fect the economy of operation; this form to be concise and yet to have sufficient data so that, when subjected to analysis by technical and practical engineers, it would give a true picture of operating conditions. Voyage Reports This form, during its early stages, was modified several times so as to meet the requirements of the differ- ent departments, as they realized the value of a continuous report of this sort in their various branches of the shipping business. The first page is headed with a brief description of the physical characteristics of the vessel, which serves to classify the type of the particular vessel covered by the report. Following this is an analysis of indicator cards which is filled out for reciprocating steam- driven vessels. A brief report of the physical condition of the various de- partments and equipment of the ves- sel is given, together with a rating based on an A. B. C. D. schedule, in which A is excellent; —A. very good; +B. good; B, fair; —B, probation mark; C, poor, -and D, exceedingly poor. The engineer officer personnel is also rated under three headings, “mechaical ability,’ “discipline” and “efficiency,” these ratings to represent A paper read before the Society of Naval Architects and Marine Engineers by C.

The engine department crew, its equipment and the operation of the vessel are also rated by the same schedule. In order that the ratings shall be of real value, the inspection must. be made by a competent, experienced and well-selected inspector, who will make an unbiased report entirely free of any personal prejudice. At the lower part of the voyage report form an outline chart of the world is given upon which is shown the particular Pee Ts See Ue Sens Beer ROE an BA Sa NT as ES oe: ee a CE oe ee oe Se ee PI ae eo ee COPPER ep aveence SERRREREE eS GS= 22 ar «mee 4 5 /MNSING VA g PL Seer aan ‘ BGee2 =: a/R alee oes : ater er ee ere a ee ee ‘ CV eer LL eee er ¢ SA” Sd NS a i ee i ae ; eS Shae Bee owe , TT err i \ i Oe ee ae ee ee SRSREMERWE Sanda wene esa Sneh ee Ae er CeCe Hee Oa SR Se cg ee Se Ce er BEELER REECE EEE ee Bae ae Re a el let oe the conditions for each of the pas- sages of the voyage. Through this system of inspection close touch is kept with the operating vessels of the fleet, and it becomes a comparatively simple matter to de- termine the relative performance of any particular vessel at any time and to direct efforts for improvement to- ward the poorer performers so as to bring them up to the standard of their sister ships. A report such as this, made at the termination of each voyage of a vessel, has a marked beneficial effect on the efforts of the CHART SHOWING IMPROVEMENT IN SEA PERFORMANCE OF A NUMBER OF VES- SELS—ALSO THE AVERAGE INCREASE IN EFFICIENCY route in which the vessel operates. This chart is used simply as a quick means of route classification. On the first page is also given the fuel sum- mary, which gives a continuous rec- ord of the bunkering and consumption of the vessel and checks the fuel con- sumption, which is shown on the sec- ond page under headings of “Sea Consumption,”~ “Port Consumption,” and “Consumption in Pilot Waters.” The second page is given over to. op- erating conditions on which are re- corded the chief items that affect the economy of operation of the engine department. The data tabulated in each of the several columns represent 22 operating personnel. They are not only kept advised as to their own performance but also of those of their sister ships. This stimulates that competitive spirit which is so characteristic of the American engi- neer and which enables him to over- come seemingly impossible obstacles. It is apparent also that by means of these inspection reports it becomes comparatively easy to determine, from an operating standpoint, the relative standard of operating efficiency of the managing operators, and in this way to materially assist in arriving at a decision as to which operators (Continued on Page 88)
