Building information management

A multi-dimensional management system is under development in a collaborative research program between Chinese and Australian universities and industry partners, led by Curtin University. The existing system will be extended in key areas to facilitate data-based decision making relating to the management of subsea facilities.

Marine environmental monitoring and impact assessment

Numerical simulation of the construction process that involves pipe laying operations and operational analysis of marine risers in deep water; both areas of which have been under development in Ocean University of China.

Structural health monitoring and safety assessment of offshore structures

The offshore structures are subjected to harsh environment and the structural safety is essentially important during its service life. To ensure safety and to prevent the occurrence of major accidents, structural health monitoring and safety assessment are required for offshore platform structures during operations. Research under this topic includes: modal identification based on vibration signals; damage detection and model updating based on modal parameters; design criteria of offshore structures; structural fatigue analysis; and assessing structural safety.

Subsea equipment technology development

Subsea equipment technology is the key technology for deep ocean exploration. These areas will require new developments in control systems; subsea power distribution and supply system; separation; dehydration; compression; multiphase flow and particle deposition control; corrosion and flow assurance. Pipe leakage detection using composites and nano-materials will be required in the development of subsea technology. Further research includes fundamental principles of the subsea power supply system, key techniques for its application, including the working fluid and heating source selection, as well as the pressure balance control system.

Hydrodynamic performance and motion response analysis of deep-water floating structures

As offshore oil and gas drilling develops towards deep-water operations, floating structures with mooring and riser systems are adopted and the hydrodynamic performance of the floater and motion response analyses are required.

For complicated floating structures with mooring and riser systems under extreme environmental conditions, many areas of research need further investigation, including extreme environmental actions on floaters, vortex induce motion of structures, vortex induced vibration of marine risers and coupled dynamic analysis of floater, mooring and riser systems.

Surveying

All surveying aspects of in-sea, met-ocean monitoring, seabed and water surface condition monitoring requires above-water and seabed installations to last 30 to 50 years with support from geospatial surveying through the use of satellite, airborne and surface observations.
