The aim of the project is to design two container units – Office and Pantry, structure capable to withstand Blast pressure located at an Onshore Oil and Gas plant at UAE. Both structures are of same dimensions 12mx3m, the design was based on American standards. The project involved multiple analysis for each unit, In-place condition for – Normal Operation Period by considering the operational loads along with wind and earthquake factors, Transit Land & Sea for considering Acceleration forces on the structure due to land & sea transportation, Blast Analysis condition for considering the effects of possible blast impact on the structures during operation and Lift condition considering effects of lifting and designing padeye. The analysis was performed in staad software, the loads due to transportation was considered as accelerations and was applied as multiplier on the loads acting on the structure. The project also involved developing structural and architectural BIM models.
The project involves design of skids and equipment supports for two floating desalination plant in Saudi Arabia. The design involves 11 equipment’s/ skids to be designed. The major challenge on the design was to provide economic sections whilst considering the acceleration effects of wave, hull deflection and wind loads. The design involves four analysis – Normal Operation condition considering the operational loads, wind loads, hull deflection and accelerations due to waves, Transit condition considering the effects of dry loads, wind load during transit period, hull deflection and accelerations due to waves, Extreme condition for considering the operational loads, extreme wind loads, hull deflection and acceleration due to waves and Lift condition for lifting and placing the structure on the Barge.
The quantity of materials has been estimated and the corresponding drawing has been done. The load datas has been given by the client. The foundation is circular with a diameter of 22m. The foundation is sized in such a way that it maintains 100 percent contact under quasi permenant load case also the lift off shall not be more than 50 percent. The foundation is designed as a plate element. The grade of concrete used is M50 and the grade of steel is Fe500D. The estimated quantity of concrete is 652.79 m3 and the quantity of steel is 55MT.
The project involves the design of dosing tanks and equipment supports for two floating desalination plants in Saudi Arabia. Each of the two floating desalination barges will utilize a Reverse Osmosis Plant to produce 50,000 m³/day during both pre-service and in-service operating conditions. A major challenge in the design was to create economical sections while accounting for the effects of acceleration from waves, hull deflection, and wind loads. The design process includes four analyses: Normal Operation Condition: This considers operational loads, wind loads, hull deflection, and accelerations due to waves. Transit Condition: This focuses on the effects of dry loads and wind loads during the transit period, along with hull deflection and wave accelerations. Extreme Condition: This analysis considers operational loads, extreme wind loads, hull deflection, and accelerations due to waves. Lift Condition: This involves considerations for lifting and placing the structure on the barge.By addressing these factors, the design aims to ensure safety and efficiency for the floating desalination plants.
ANALYSIS AND DESIGN OF ERI SKID
Project is carrying out the engineering procurement and construction for the floating desalination plant project. The floating desalination plant project, comprising two 50,000m³/day capacity desalination barges. as part of this project, it has been tasked with designing and analysing the skid, a critical component of the barge. The skid is a custom-designed, steel-framed platform fabricated from I-beams, angles, and channels to support pipes, equipment, and other essential components. its primary function is to facilitate easy movement, storage, and installation of heavy equipment. The skid design ensures efficient transportation and installation at the final site location, enabling rapid commissioning of the desalination process.
The project entails designing a skid equipped with four units, including a walkway. I have been tasked with designing and analysing the skid, a critical component of the barge. The skid has a column height of 8.3 meters, while the walkway stands at 9 meters. The structure must accommodate wind loads, as well as pitch, heave and roll forces, in addition to piping loads. Hogging and sagging have been considered for the structure. Baseplate and splices are designed accordingly. We have designed using AISC ASD standard codes to ensure the structural integrity and safety of the design.
