Fig. 9 - Details of stern arrangennents for 48,500-TDW tanker model 



Table 2 



EHP and SHP Tests with 48,500-TDW Tanker 



(design speed 16 knots at 16,000 SHP) 



From the tables, it may be seen again that the Hogner-type afterbody is 

 really bad from a viewpoint of resistance; however, in the loaded as weU as in 

 the light condition, the tankers with the Hogner-type stern and nozzle require 

 less power than the conventionally shaped tankers. The reduction in SHP is 4.i 

 percent for the 32,500-TDW tanker in the loaded condition at the design speed 

 of 17 knots. A reduction in SHP of 2.7 percent has been found for the 48,500- 

 TDW tanker in the loaded condition at the design speed of 16 knots.
