Installation Engineering

Our detailed understanding of hydrodynamics, vessel motions and operational considerations, allows us to conduct installation engineering for risers and many other subsea systems and components.

Our experience includes subsea pipelines (reel-lay, j-lay, s-lay), umbilicals, trees, manifolds, PLEMs, PLETs and driven suction pile foundations. We have provided installation engineering support to many installation contractors all around the world, and have also provided guidance to operators in selecting installation methods and cost optimisation.
