The Ability LNG, LPG and General Port Vessels Maneuvering in Berthing Zone of IRAN LNG Project Jetties in Persian Gulf
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).
