Local scour below offshore pipelines on calcareous sediments. This project will improve predictions of erosion around subsea structures in calcareous sediment, allowing potential pipeline self-burial. This will reduce the considerable costs currently spent on pipeline stabilisation and increase the viability of Australia's offshore resources and the competitiveness of the Australian oil and gas industry.
Hydrodynamic forces on small diameter pipelines laid on natural seabed. This project aims to improve predictions of hydrodynamic forces on small submarine cables and pipelines through comprehensive experimental modelling at 1:1 scale coupled with development of predictive numerical models. The focus will be on forces in unsteady flows. Present industry guidelines do not make allowance for potential reductions in forces for small diameter pipelines whose diameters are a similar length to the effe ....Hydrodynamic forces on small diameter pipelines laid on natural seabed. This project aims to improve predictions of hydrodynamic forces on small submarine cables and pipelines through comprehensive experimental modelling at 1:1 scale coupled with development of predictive numerical models. The focus will be on forces in unsteady flows. Present industry guidelines do not make allowance for potential reductions in forces for small diameter pipelines whose diameters are a similar length to the effective seabed boundary layer, thereby leading to overly conservative and costly stability design. Results from the experimental program and numerical model developed are expected to be used to improve the current industry design guidelines.Read moreRead less
Predicting scour and scour-induced settlement of subsea infrastructure. This project aims to develop improved predictions and understanding of the potential and extent of scour and scour-induced settlement of subsea infrastructure on mobile seabeds. This is expected to enable scour and settlement to be accounted for directly in engineering stability and serviceability design, overturning current practice which ignores both effects on the basis of using scour protection and costly maintenance and ....Predicting scour and scour-induced settlement of subsea infrastructure. This project aims to develop improved predictions and understanding of the potential and extent of scour and scour-induced settlement of subsea infrastructure on mobile seabeds. This is expected to enable scour and settlement to be accounted for directly in engineering stability and serviceability design, overturning current practice which ignores both effects on the basis of using scour protection and costly maintenance and remediation. Development of accurate predictions is expected to be achieved through physical model testing, numerical modelling and analysis of field data. Predictions should improve subsea reliability and lead to omission of scour protection in some situations, increasing international competitiveness of our offshore oil and gas industry.Read moreRead less

Connections for hybrid steel-timber-concrete structures. Connections play a vital role in overall performance, reliability, and adaptability of civil structures. This project aims to develop innovative, easy to fabricate and efficient connections for hybrid structural systems that fully exploit advantages of steel, concrete and engineered timber to reduce the self-weight, cost and negative environmental impact and enhance opportunities for deconstruction, reusing and upgrading of the structures. ....Connections for hybrid steel-timber-concrete structures.

Game changing anchoring solution for Australia’s deep water gas development. This Fellowship aims to establish a novel dynamically installed anchor shape for economic and safer mooring of floating gas drilling platforms in Australia’s deep water calcareous seabed. The novel anchor pairing with the advanced floating platforms are expected to allow for unlocking Australia’s 50% gas reserves that are considered to be stranded.

This Fellowship aims to establish a novel dynamically installed anchor shape for economic and safer mooring of floating gas drilling platforms in Australia’s deep water calcareous seabed. The novel anchor pairing with the advanced floating platforms are expected to allow for unlocking Australia’s 50% gas reserves that are considered to be stranded. This Fellowship expects to extend a sophisticated numerical analysis technique and a soil constitutive model, and use field testing in the Swan River and centrifuge modelling for extensive investigation on the novel anchor shape, leading to calculation methods for assessing the anchor embedment during dynamic installation and capacity under operational monotonic and cyclic loadings.Read moreRead less

Thermal-induced unilateral plate buckling of concrete pavements: design and evaluation. The project addresses the upheaval buckling of concrete pavements, which is caused by increasingly frequent heat spells. It will consider both the vulnerability assessment of existing pavements, and the design of new pavements made from low-carbon geopolymer concretes (which are lighter than conventional pavements) against upheaval buckling.
