In oil & gas E&P, safe and reliable operations are of paramount importance to the industry. Asset integrity should never be compromised and risk management is critical to ensure lives and marine environment are safeguarded.

With enhanced oil recovery techniques, operators are stretching the existing reserves with assets that are reaching their design service life. These aged assets are often susceptible to failures due to mechanical degradations and harsh offshore environment.

Oil exploration has also inevitably moved into deep-sea as shallower oil wells become depleted. The offshore assets are installed in deeper water and are increasingly inaccessible. The associated cost of asset maintenance increases exponentially for deep-water regions resulting in the need for technological innovations in asset integrity & risk management. Integrity assessment and risk management solutions, anticipation of possible failures of systems and emergency response plans in the event of asset failures would be critical.

The offshore assets covered include offshore structures, subsea and down-hole equipment. The key research objectives are:

a) Identification of safety critical elements (SCEs)
The weakest structural components that are most susceptible to external forces, cyclic loadings and harsh environment known as safety critical elements should be identified.

b) Reduction of reliance on manual inspection
The inaccessible assets in deeper water and harsher environment drive the need for remote and autonomous inspection and maintenance which are increasingly reliant on sensor based technologies.

c) Low hardware overheads
Cost is one of the major considerations when sensors and wireless systems are installed. Such overheads include the cost of manufacturing the sensors and systems, power requirement as well installation compatibility with the existing assets.

d) High reliability systems under harsh environment
The increasingly harsh environment at deeper water with strong waves and currents as well as deeper wells with hostile chemicals and high pressure high temperature (HPHT) pose significant technical challenges. Sensors and systems must survive such environment with high reliability.
