Abstract :
For the purpose of having a safety navigation, the transportation path,
deployment of carrier, physical specifications, locations and … have high
level of importance. In this research, along with the above mentioned factors,
we have compared the result with technical standard and commentaries for
port and harbor facilities in Japan, and to analysis both advantage and
disadvantages of them. The IRAN LNG project (ILC), will product the overall
amount of 10/80 million tons of LNG per annum. Based on the type and
capacity of LNG ship (Membrane Type,150000 m3 ), 13 vessels and 6 tug
boat are estimated, mostly considered as high capacity LNG carriers. Since the
IRAN LNG ships enter to terminal on ballast and after loading departure and
also with considering number and marine traffic on South pars, one way
channel with 0.5 L (L is length of ship) considered. On this base, we need
Maximum width of 157.5 m and minimum 122m (for LNG Ships), and
Maximum width 120m and minimum 89m (for LPG Ships). Area,
circumference and diameter of basin with anchorage & buoys on general jetty
that in collusive general Cargo, Sulphar & Ro-Ro berth respectively are
154610 m2, 1830m and 320m that covered Japanese’s standard completely
but about turning circle, we have area, circumference and diameter
respectively 5896 m2, 250m and 708m which doesn’t coordinate with Japan’s
standard except only one subject (Sulphar berth with aids tug boat).
