Jas, E., Campbell, D., Chamizo, D., Cheng, L., Erbich, C., (2012) “Pipeline Stabilisation using Pre-Trenching and Sand Backfill” 31st International Conference on Ocean, Offshore and Arctic Engineering, Brazil, American Society for Mechanical Engineers (ASME)

Stabilizing large diameter natural gas pipelines on the seabed against extreme hydrodynamic loading conditions has proven to be challenging in the northwest of Australia. Tropical storms, which affect the area annually between November and April, can generate wave heights exceeding 30 m and onbottom steady-state currents of 2 m/s or more. Consequently, in shallow water […]

Campbell, D., Chamizo D., Modra, D., Jayewardene, I. (2012) “2D and 3D Physical Modelling of Current and Wave Interactions for Rock Berm Design”, Journal of Shipping and Ocean Engineering

Although empirical methods exist for the design of submerged rock berm structures, significant optimisation may be achieved through physical model testing. This paper outlines the 2D and 3D physical modelling undertaken to optimise the design berm dimensions and armour size for a berm structure require for protection of hydrocarbon pipelines. The return period conditions tested […]

Jas, E. Campbell, D., Ryan, J., White, D. (2011) “A fluid-pipe-soil Approach to Stability Design of Submarine Pipelines,”, Offshore Technology Conference 2011, Houston, (OTC)

The conventional approach to submarine pipeline stability design considers interactions between water and pipeline (fluid-pipe) and pipeline and seabed (pipe-soil). The seabed is typically assumed hydrodynamically stable in this approach. Interactions between the water and the seabed (fluid-soil) are generally considered only as an afterthought. A new approach for assessing the stability of submarine pipelines […]

Jas, E., Campbell, D., McMaster, S., (2011) “Pipeline Shore Approach Design – Case Study” 30th International Conference on Ocean, Offshore and Arctic Engineering, The Netherlands, American Society for Mechanical Engineers (ASME)

An insight is provided into the design of a large diameter high pressure gas pipeline shore approach for an LNG project off the coast of North Western Australia. The shore approach is located in a challenging and congested area, within one of Australia’s busiest ports. In close proximity to the pipeline route are two existing […]
