  7. Abstract:
  8. Nowadays, many offshore jacket platforms have been built in all over the world for excavating oil and gas. Due to cost of construction and maintenance, they are considered as national assets. Jacket platforms are always under various types of loads in their time life, so they cause some damages to them. Hence, on time damage detection can prevent possible extravagant costs of repair and reconstruction. Because many jacket platforms are in Iran, this issue can be very important.Structural health monitoring (SHM) improvised to ensure safety and detect damages of structures uses sensors. They transfer data received from structures to the computers in order that after interpretation of data, they can be transformed to structural parameters. As a result, one of the significant parts of SHM is sensors. Although centralized development continues on sensors technology, there is still significant uncertainty in deciding on the number of sensors required and their location. In this field, many methods have been developed. Some of them are used for special projects and others are used in common structures.
    In this thesis, six common methods have been investigated. After two dimension modeling a jacket platform located in south pars gas field, the sensors have been allocated by these methods. To compare and select the best method, five comparative methods with variety of criterions are utilized.Finally, according to the results and also considering specific situation of these jacket platforms, the best method has been selected and announced
