Offshore Structural Systems
As deepwater floating systems and shallow water jackup rigs operate in harsh environments, structural integrity of key subsystems, including connections, moorings and risers and foundation systems, are critical to safe operations. The systems approach undertaken by NUS Engineering on offshore structural systems addresses key issues for floating and bottom-founded structures. The research areas include structural integrity management, innovative structural systems, wave-structure interaction, marine operations and installation engineering.
Hydrodynamics and Wave-Structure Interactions
Simulation and modelling are widely adopted in the design of floating structures, which includes SPAR, TLP, FPSO and Semi-submersibles. Ongoing research into simulation and modelling include potential flow modelling, computational fluid dynamics (CFD), viscous CFD and meshless particle-based methods to develop advanced simulation techniques , as well as to address these complex issues. Our faculty members are also closely involved in the development of the next generation deepwater ocean basin systems (DOBS) simulation capabilities. Effort includes oversight of the wave and current generation system and basin equipment designs and integration of numerical modeling to study the behavior of floating platforms in harsh environments.
At NUS Engineering, extensive centrifuge and numerical model studies have been carried out to investigate the behavior of jackup spudcan foundation in relation to foundation punch through an extraction, interaction between spudcan and adjacent pile, and footprint-spudcan interaction. As oil and gas exploration and production advance into deep and ultra-deep waters, research into foundation anchoring systems and pipeline-soil interaction are increasingly more important. Geohazard, due to submarine landslide impact on pipelines, is also an important research area.
Subsea engineering research aims to develop technologies to augment and compliment current technologies employed in the subsea oil and gas production, processing and transportation, as well as to overcome the challenges faced in flow assurance. The research carried out includes flow assurance, fundamental multiphase flow research, subsea oil and gas production amd transportation, and subsea processing to overcome challenges faced in subsea systems.
Petroleum Engineering & Geosciences
Research in Petroleum Engineering and Geosciences seeks to develop methodologies to improve our characterization of sub-surface reservoirs. The research programme integrates geophysical measurements such as seismic and electromagnetic surveys, downhole and surface measurements to infer for the properties of subsurface reservoirs and geology. The main research areas include rock physics modelling, downhole measurements, seismic inversion and tomography, and reservoir geomechanics.
