Engineering

 

Taking an idea through all the steps from the whiteboard to realisation, requires a wide range of knowledge and experience. Sevan is involved in all these steps, but we are focusing on some core disciplines where we try to be best in class.

Within these core disciplines, you will find highly skilled engineers performing advanced analysis to support their decisions and design solutions.

 

Sevan SSP has a dedicated, experienced team with the unique benefit of having designed, constructed and operated Sevan SSP floaters.

Marine Analysis

 

Marine analyses are essential in Sevan’s core business activities, from initial calculations of new floating concepts to calibration of numerical models towards model test results and detailed, specialized analyses. Sevan has extensive experience and expertise within hydrodynamics, mooring- and offloading system design.

Understanding the hydrodynamic behaviour of our floaters is crucial in all aspects. From early design to operational phases offshore, we ensure the integrity of the units through numerous marine analyses.

 

     

    Typical engineering activities related to marine analysis are:

    • Model testing in wave basin
    • Wind tunnel testing
    • Calibration of numerical models
    • Wave impact/Slamming analyses
    • Green water analyses
    • Sea sickness considerations
    • Various hydrodynamic analyses
    • Mooring analyses
    • Mooring system specifications
    • Hook-up and installation analyses
    • Offloading operability simulations
    • Dynamic hose analysis

      Hull and Structure

       

      Hull design is the essential part in Sevan’s core business activities, from the feasibility design to detailed design of the floating concepts. The design phases involve the whole project cycle from early design proposals to both FEED and detailed design activities as well as support to construction team. The methodology is based in advanced calculations, best engineering practise from earlier executed projects as well as close dialogue with client to support the functional requirements demanded by the client. 

      Design development is based on state-of-the-art integrated stability and structural 3D models ensuring update to date design development. Numerical models are developed for efficient analysis of the hull structure based on 3D design models. The models are developed based on extensive experience and expertise in design development of cylindrical hull structures.  

       

         

        Typical engineering activities related to hull and structural design analysis are: 

        • Stability analysis  
        • 3D model development 
        • Advance finite element calculations.  
        • Spectral fatigue calculations 
        • Wave impact/Slamming analyses 
        • Green water analyses 
        • Collision analysis  
        • Global finite element analysis 
        • Transport analysis  
        • Construction support
