It is supposed that the conventional bulker repeats a voyage throughout a year at the Suez route, from Yokohama to Hamburg. Table 4.3.4 shows the results of a freight calculation. The voyage-days are estimated to be approximately 39 days, which include an anchorage days and Suez canal transit days. The freight cost is estimated to be 18.1 $/ton and it is little less than one in the simulation for the icebreaking 50BC (I-50BC), which ranges between 20.3 and 21.6 $/ton for 10 years as Table 4.3.2. Thus, the freight profltability for the I-50BC even at selecting route is little inferior to one for the C-50BC, if a year round operation is considered.
On the other hand, as for the summer operation for about 4 months, the freight cost for the I-50BC is 18.8 $/ton and there is little difference between two bulk carriers.
