Shear Stress Amplification and Scour Around Subsea Structures
Project Description Offshore and coastal infrastructure are susceptible to local scour, where sediment is removed from the area adjacent to the structures due to waves and currents. This phenomenon can endanger the stability of seabed structures, such as offshore energy infrastructure or artificial reefs at beaches. Scour remediation and protection is costly and improved design […]
Shallow Penetrometer – Measuring In-Situ Soil to Soil Friction
Project Description The shallow penetrometer is a creative extension of the conventional cone, T-bar and ball penetrometer, but with added actuation, control capabilities and new types of sensors providing more detailed measurements of soil response. A new ring-shaped penetrometer tool is proposed that generates soil-to-soil shearing using milled slots (with drainage holes) across a ring […]
Performance Evaluation of Anti-Scour Frond Mats
Project Description Pipelines and subsea structures can cause significant and rapid sediment scour when deployed on mobile seabeds. This results in the need for frequent and costly inspections to assess reliability and serviceability. Typical scour mitigation solutions include dumping of gravel, rocks, sandbags and gabions in the scour holes and eroded areas around pipelines; however, […]
Detecting Corrosion Under Insulation
Project Description In the oil and gas industry corrosion of pipes can lead to serious leaks that can disrupt production as well as have serious safety implications. At large sites, e.g. Woodside’s Karratha Gas Plant, the pipes carrying liquefied natural gas (LNG) need to be insulated to maintain low temperatures of the liquefied gas. Ingress […]
