Pipelines & Subsea
Wall thickness, stability, spans, pipelay, buckling and CP.
What this expert provides
The Pipelines & Subsea expert designs and checks submarine pipelines and flowlines: wall thickness to DNV-ST-F101, on-bottom stability and the concrete coat, free spans and the allowable span, S-lay and J-lay analysis, upheaval and lateral buckling, and cathodic protection with the anodes needed.
Expert Profile
Screens every check with its utilisation: pressure containment, collapse and buckle propagation, quasi-static stability with the seabed wave and current kinematics, DNV-RP-F105 span frequencies and onset, lay tension, layback and strains, Palmer upheaval download and cover, DNV-RP-F103 anode mass and spacing. The detailed analyses (DNV-RP-F109, span fatigue, lay with stiffness) are scoped and routed; the lay data go to the installation expert.
