Rapid Bar Coding and DNA Sequencing Kit
Project Description To improve understanding of how marine growth accumulates on and around subsea equipment, Woodside (in collaboration with the equipment provider) has placed an “Anti-Marine Growth Structure” (AMGS) on the seafloor with a number of equipment pieces. Using this structure they are interested to find out which marine animals might be responsible for the […]
Design Engineering for Seabed Porcupine
Project Description UWA continues to undertake globally-leading research into the behaviour of subsea cables and pipelines, with a particular focus on how the hydrodynamics are affected by the cable interaction with different types of seabed. Through the research undertaken by a number of researchers, significant progress has been made in developing an improved understanding of […]
Low Cost Under Water Data Acquisition System
Project Description Any offshore development requires the collection of subsea measurements enabling the live-streaming of in-situ research data. Typically the measurements are collected and processed in an underwater data acquisition system (U-DAQ) that enable the transmission of the data to shore. Data acquisition system used in industry are extremely expensive and affect significantly the budget […]
Towards Improving Pipeline Stability Design For Solitons
Project Description Non-linear Internal Wave (NLIW) induced currents are prevalent at numerous locations offshore the North West Shelf and elsewhere around the world. Routing pipelines through areas of significant NLIW activity requires careful design to ensure the pipeline remains stable when subjected to large near-bed currents. The aim of this project was to review (1) […]
Planning the Recovery of an Anti-Marine Growth Structure
Project Description Oil and gas subsea equipment is often impacted by marine growth and leads to failure that is costly to the industry. To investigate how different types of equipment react to exposure to seawater in deep waters, Woodside deployed an “Anti-Marine Growth Structure” (AMGS) in one of their fields. During deployment, this structure provided […]
Rapid Greenwater Testing in the Wave Flume
Project Description During concept design for new offshore facilities, decisions often need to be made with only limited time and resources (for example, determining the hull geometry of an FPSO). Experimental testing was undertaken in the 54 m long wave flume at the University of Western Australia (UWA) to investigate the effectiveness of a sponson […]
SLAM – Swell Local Adjustment via Monitoring
Project Description Numerical wave models provide detailed information about wave conditions up to seven days in advance, and are critical to a number of industry applications – both for marine safety, and to inform the best time for complex offshore operations. However, virtually all operational wave models rely on phase-averaged wave models – meaning that […]
Robust, Automated Cameras for Biodiversity Assessments from Industrial ROVs
Project Description The addition of lightweight, smart cameras to industrial ROVs can enable scientists to gather information on marine growth and fauna associated with offshore infrastructure. Knowledge of the ecological value of infrastructure in our ocean is required to inform best practice decommissioning decisions. The Department of Primary Industries and Regional Development and UWA have […]
A Feasibility Study of the Detection of Pipeline Dynamics Response Using Distributed Optic Fibre Strain and Discretely Located Accelerometers
Project Description Intrinsically safe sensing of structural response is one of the important challenges for condition monitoring of long-distance oil and gas pipelines. The distributed acoustic sensing (DAS) using coherent Rayleigh backscattering in an optical fibre offers an attractive technique to meet this challenge. In this project, DAS technique is applied to measure the distributed […]
Elongation of Pipeline Spans Over Buckle Initiators
Project Description Buckle initiators (BI) are used to support subsea pipelines which are designed to buckle to release stresses in the pipeline. The free-spans formed from BIs will be subject to local scour and potentially vortex-induced-vibration. This project aims at assessing the scour process under free-spans formed from BI and how to reduce the impact […]
