In accordance with the characteristics of the work load on the bridge structure, namely: the nature of static or dynamic loads and the behavior of deterministic or stochastic, then the offshore rig design known several stages of analysis tailored to the needs and the type of bridge is designed. Several examples of analysis is often done in the design of the pavilion are as follows:
i. Static Analysis
This analysis aimed to determine the strength of weight-bearing structures in good operating under normal conditions and storm conditions that may occur during operation. In static analysis, structural strength assessment conducted according to three criteria, namely: for all elements of structure of (member) made AISC Check, for the connection cylinder (tubular) API Check done and to see the actual voltage magnitude happening to permit voltage structures with Unity Check (Interation ratio Check)
ii. Pile Analysis
Analysis of pile (Pile) performed only on fixed platforms or structures that are permanently connected to the seabed. Analysis of the stake to know the size of the support structure and feasibility of the foundation
iii. Dynamic and Fatigue Analysis
Analysis of fatigue (fatigue) done to determine the age structure / connection as a result of repeated operation of the load either normal or storm conditions during the life of the structure of the operation. To structure offshore rigs that have natural periods of more than 3 seconds, the contribution of dynamic load of the structure becomes the dominant behavior
iv. Seismic Analysis
In earthquake-prone areas need to do the study on the ability of weight-bearing structure by the earthquake, especially for fixed bridge.
v. Loadout Analysis
Load-out is a process where the platforms that have been developed in the dock to transport dipindahan to be taken to the operation. This process requires precision and caution given the environmental conditions of uncertainty, the large size of the structure and limitations of facilities and investment risk / accident.
vi. Transportation Analysis
During the bridge transfer to the operating location many factors that can cause failure of the operation, are like the availability of transportation equipment (ships / barges), towing vessels (tug boat), environmental conditions, etc.. Analysis of transportation related analysis and stability Fastening sea transport
vii. Installation / stability analysis
Placement rigs operating location requires a quiet environment with adequate support tool, and its impact on the behavior of the bridge is a destination and this analysis.
viii. Pile driven analysis
For fixed bridge should dilakuan this analysis and the ability to see patterns erection.
