The Subsea Australasia Conference scheduled to take place later this month in Perth will explore the commercial and technical developments impacting the subsea industry, including new advances in infrastructure, subsea operations, pipelines and connection systems.
The Conference is a joint initiative of Subsea Energy Australia, Subsea UK, the Society for Underwater Technology (SUT) and the Australasian Oil & Gas Exhibition & Conference (AOG).
Morten Nilstad Pettersen, Risk Management Consultant at Scandpower AS Pettersen will be in Perth this month to discuss the identification of interlinked failures in subsea systems and share experiences from the Norwegian Continental Shelf at the Subsea Australasia Conference.
According to Pettersen, conventional risk management methods alone may not be sufficient to identify failures in complex subsea systems, such as the BP Deepwater Horizon oil spill.
Most accidents, such as Deepwater Horizon occur due to a series of complex and interlinked failures, often caused by human decision-making, and conventional quantitative risk management analyses should be supplemented with creative multidisciplinary methods to help detect such failures.
Pettersen says that the focus of conventional quantitative risk management methods is mainly related to generic hazards, adding that the total risk picture can be obtained by supplementing these methods with multidisciplinary methods, such as HAZard and OPerability (HAZOP), which identify the operational specific or interface hazards that cause most failures in subsea systems.
Pettersen said Norwegian authorities required subsea operators to perform proactive qualitative risk management methods during a project life and many operators had come to favour HAZOP, a risk assessment forum based on the principle that a team approach to hazard analysis will identify more problems than when individuals working separately combine results.
Pettersen also said that Australia’s fast-growing subsea industry could learn much from the experiences of operators in the Norwegian Continental Shelf.
The Norwegian way of using the HAZOP methodology is particularly relevant for Australia in terms of similar challenges being faced with subsea installations.
Organised by Diversified Exhibitions Australia , the Subsea Australasia Conference is being held at the Perth Convention and Exhibition Centre from 22 February to 24 February.
