Leading sediment scientist Piers Larcombe warns that disruption to long-term sediment transport along deeper water pathways could force a reassessment of the placement and design of subsea oil and gas projects and pipelines in all-important regions such as the North West Shelf.
Chief Sediment Scientist at RPS MetOcean, Larcombe will look at changes to pathways and discuss the implications for oil and gas development and regulation at the Subsea Australasia Conference in Perth.
According to Larcombe, there was a need to better understand the effects of cyclones and tidal currents in driving sediment transport pathways in Western Australia’s North West Shelf and the upper continental slope over the decades.
Larcombe said disruptions to sediment transport pathways could lead to increasing marine habitat change and greater risks to submarine structures such as oil and gas pipelines.
He added that the oil and gas industry needs to assess the scientific evidence for long-term sediment transport pathways and the risks involved so activities and structures can be designed to reduce the potential disruption.
Larcombe, who has more than 25 years of experience studying the geology, sedimentology, oceanography and development of coastal and marine environments, is one of several experts taking part in the Subsea Australasia Conference from 20-22 February.
The conference will feature topical sessions focused on new advances and challenges in subsea operations, drilling and well management, marine sediment transport, global demand for subsea talent and subsea fields of the future.
A joint initiative between Subsea Energy Australia, Subsea UK, the Society for Underwater Technology and the Australasian Oil & Gas Exhibition & Conference (AOG), the conference is being held in conjunction with AOG 2013 at Perth Convention and Exhibition Centre.
