Abstract
Applying the new formula for calculating economic efficiency of Diesel freighters, which is introduced by the author, he investigated the economic efficiency of 24 Diesel freighters of different size and speed under four conditions of different load, runningbetween ports of four different mileage, i. e. economic efficiency for 384 cases altogether is calculated.
Drawing several diagrams by plotting the results of calculation, he obtained his general conclusion regarding the economical speed and size of cargo vessels.
The contents of the paper are as follows:-
Foreword.
Definition of economical speed and size, economic efficiency of Diesel freighters and the fundamental formula for calculation of such economic efficiency.
Limits of calculation of economic efficiency of Diesel freighters.
Principal particulars of Diesel freighters for which economic efficiency is calculated.
Process of calculating earning, expenditure and economic efficiency of Diesel freighters.
