Abstract:

The Crane-assisted upending procedure for installation of jacket platforms requires heavy floating cranes. The alternative way to install jacket platforms is the selfupending’’procedure, in which belt-shaped Buoyancy tanks are deployed to self-upend the jackets. This beltshaped buoyancy tanks comprise different tanks welded together. Hence, they cannot be deployed to self- upend other jackets which have different dimensions. The new positioning of buoyancy tanks on Jackets has been presented in this paper which makes the self-upending procedure much more cost-effective thanks to the Modularization of Buoyancy Tanks. By virtue of this method, buoyancy thanks are no longer welded together;therefore, they can be used to self-upend the other jackets with different dimensions. Furthermore, before positioning jackets on the seabed, the stability of floating jacketsincreases due to the new arrangement of Buoyancy tanks on jacket. Parametric study demonstrated that, with this new arrangement of buoyancy tanks, self-upended jackethas a considerable stability. This new arrangement has been applied on two different existing jackets in Persian Gulf, located in 40 and 70 meters of water depth.
