Air Cooler Analysis Solution in Ceasar 2

Went through all your opinions about modelling of air cooler in Caesar II and thrust block arrangement. As an experience of the same I am sharing my corresponds with air cooler vendor. We are doing engineering of a hydrogen plant located in India. During engineering we came across stress analysis of air cooler piping. During initial stages of analysis the nozzle loads were to high because of very stiff piping connected to it. To reduce nozzle loads we have planned to do the piping as flexible as possible. Then we lend up in very big loops and supporting that loop piping becomes very difficult task. Then we tried mechanical linkage arrangement. The cooler consists of 6 bays. We fixed the inner supports of middle bundles and outer bundle are connected to each other with mechanical linkage (Thrust block). The air cooler is modeled with actual weight as given by vendor. Then we communicated the same arrangement to vendor with the displacements at each supports of outer bundle. Accordingly they have provided the thrust block connection. Also they have shared their experience on the same subject. The vendor has already supplied such kind of air coolers to other projects in India (Well known Indian refineries). I have the information related to air coolers supplied with mechanical linkage arrangement. The air coolers in previous projects supplied by that vendor are working well since its commissioning in 2003.
