eSubsea can guide you through the complexity of offshore and subsea codes, standards and recommendations and help decide and provide a list of which codes, standards and recommendation are applicable for your assignment.
Codes and Standards Drive the Design
In particular, the choice of codes and standards for the design of subsea structures, template and manifolds, subsea connection equipment, PLET, lifting frames, padeyes and lifting sets will affect the installation requirements and limitations, but also cost. It is essential to used the correct subsea standards to ensure that the safety level is as required when performing both structural and piping analysis.
Together with the design load estimation, this is one of the first steps of any offshore or subsea engineering and design task and will be documented in the project design basis.
