Extensive track record expedites design selection and engineering 

We have an extensive track record in global dynamic analysis and cross-section verification of umbilicals for both shallow water and deepwater applications globally. Our in depth understanding of subsea umbilicals and their in-service response enables us to confirm the suitability of an umbilical design for a specific application quickly and easily.  

For dynamic umbilicals, we conduct extreme load, wave fatigue and VIV response assessments, as well as define installation envelopes and assess of clearance from adjacent risers, mooring lines or other structures.  

Collaborative process to develop the most robust solutions 

Our services cover conceptual design, through to detailed engineering and working closely with operators and umbilical manufacturers as part of that process we are able to optimise umbilical designs for maximum operability and fatigue performance. Likewise, we also help operators optimise their subsea field layouts to improve umbilical configuration and installation methods.
