We have worked on a large number of sea-based materials handling projects, involving significant structural stress and fatigue analysis. Typically, structures are fabricated assemblies so we have to pay special attention to welded and bolted connections, including mounting systems to FPSOs & other vessels and wave-derived loading conditions. We are familiar with the requirements of API 16F for marine drilling riser equipment.
We have helped some of our consulting clients develop their own in-house FEA capabilities through the supply of ANSYS software, training and on-going technical support.
Likewise, our fluid dynamics team has undertaken a range of valve, subsea stab connector and ship-based fluid transport simulations considering both flow and thermal issues. We have also supported umbilical connector clients who use ANSYS electromagnetic capabilities to study electrostatic and eddy current effects.
Considering the large capital costs of subsea equipment together with the challenge of maintenance, our ReliaSoft tools help clients apply reliability techniques in accordance to practices recommended by API RP 17N. We provide gap analysis and full consulting services to help equipment manufacturers and operators plan and manage their technical risk strategies.
For operations involving the movement of sea-bed sand and soil, such as trenching or development of foundations, we support subsea companies to undertake stability and settlement analysis using leading geotechnical software. PLAXIS offers several material options for undrained soil behavior encountered offshore, such as the NGI-ADP and soft-soil creep models.
