OFFSHORE PLATFORM REFURBISHMENT
OFFSHORE STRUCTURAL ANALYSIS
FEM Analysis has become an integral part of structure design for offshore units. The usage of Load Resistance Factor Design (LRFD) in structure design has made it essential to simulate the structure behavior under various loading conditions and check the true resistance of structure.
The very nature of marine environment plays an important role in Marine and Offshore structural design. It is always a challenge to simulate the working environment and design an effective structure. Analysis using Finite Element Method (FEM) is a convenient tool to simulate the environment accurately and design the structure to withstand the derived loads.
It's not about designing a structure to satisfy rules and codes; it's all about practical but optimized and safe Structural Design. Structure verified with FEM analysis gives advantage to client for a design which is:
-Safe under various combination of complex loads
-Optimized structure in terms of weight, space, material and cost
-Checked for risk based load and resistance
-Faster approval and review at class end
