and average service time for the ship = 20 hours. How long the wharf should be, in order to fulfill the standard of UNCTAD 1978? How long the wharf should be, if the working hour is increased to be 20 hours/day. A container terminal has “berth through put” of 650 TEUs/m/year.

53 ANSWER Case 1 Based on UNCTAD-78, n = 4 BOR = (Vs.St)/(365. n) = (1025.20/10)/(365.4) = 1,4 140% > 60 %, it doesn’t fulfill the UNCTAD requirement Considered the wharf >= 6 berth, BOR = 0,70 n = (Vs.St)/(365. BOR)= (1025.20/10)/(365. 0,70) = 8 berth OK L = 8 x (350 x1,1) + 0,10. 350 = 3115 m Working time 20 hour/day, consider 5 berth, BOR = 0,65 n = (Vs.St)/(365. BOR)= (1025.20/20)/(365. 0,65) = 4,3 berth 5 berth L = 5 x (350 x1,1) + 0,10. 350 = 1960 m BOR = (Vs.St)/(365. n) = (1025.20/20)/(365.5) = 0,56 56 % < 65 % fulfill the UNCTAD-78 requirement Case 2 Ha m Bs Sth Sf DT T A 6 , 1 15690 ) 40 , 0 1 .( 4 , 2 . 4 . 365 29 . 5 . 350 . 650 ) 1 .( . 365 . . 2
