This paper aims to provide an innovative scenario for transportation and lowering installation of heavy caissons of 18000 tons for Persian Gulf Bridge. The project is supposed to be carried on in Bohal port from Hormozgan to Qeshm Island in Iran. There is a heated controversy over the suitable scenario to do the operation safely and lower the caissons correctly under sea to position them on their exact location. Due to this a comprehensive study is need to take heed all aspect of the operation. The study will include a discussion on both sides of installation and transportation and give a deep-rooted insight over the excuvation plane for the operation.
The procedure for transportation and lowering of heavy caisson in sea in range of 15000-20000 tons are complicated scenarios. There is no clear literature in regard to this study from previous researches. The purpose of this article is to present a suitable and innovative scenario for transportation and lowering of 18000 tons caissons for Persian Gulf Bridge. Caissons will be constructed in dry dock, but due to its heavy lightweight the available floating cranes couldn't transport and install it independently. So a proper and safe scenario is presented based on a Catamaran which is proposed to be two connected barge together by a truss structure. All procedure is described related to this catamaran and illustrated for each scenario for better conception. One of the most advantages of this scenario is the decreasing of operation procedures and also increasing the safety of the operation and its accuracy. Finally a flowchart related to presented scenario is presented.
Characteristics of persian gulf bridge (iran)
Persian Gulf Bridge is proposed to connect Bohal port from Hormozgan to Qeshm Island. Transportation of its caisson will be done in a direct rout of about 5.5 km that its characteristic is shown in Table 1 and Figure 1. It should be noted that the lifting weight is very important in installation procedure and will be discussed later .
