This project has developed a stainless steel additively manufactured valve body which is ready for use in service. This has been developed alongside Woodside service providers and suppliers.
Additive manufacturing qualification
A qualification and verification procedure is being developed to be used in Woodside for 3D printed parts. Monash's additive manufacturing team and Woodside's materials and technology team mapped out where industry standards could be used and where new procedures need to be developed.
These standards will be developed in 2020 to provide a clear procedure on how 3D printed parts can be put into service and increase the uptake of 3D printed parts in Woodside.
Corrosion under insultation probe
This project has developed a probe for detection of corrosion under insulation which is being deployed to inspection teams in 2020. Expected to become part of the inspection teams standard operating procedure by Q3, 2020.
Auto plant layout
Software package for the design and optimised layout of plant processes and equipment continued to be developed in 2020. Auto Plant Layout system was a finalist at the 2019 Woodside Awards (Innovation Category).
Large format multi metal fabrication and corroded surface repair via additive manufacturing
A portfolio of work focused on utilising Direct Laser Deposition technology to fabricate multi-metal components on a range of metals and surface types including curved and corroded surfaces for in-situ applications.
A research study on the duplex and super duplex stainless steel fabricated by additive
manufacturing was completed in 2019. World first results in mechanical and corrosion properties were shown highlighting ability to achieve as-wrought properties. This provides a new pathway to fabricate duplex steel components, not achievable through commercial routes.
Stainless steel corrosion arresting
A barrier wrap coating has now been approved for use within Woodside to arrest pitting corrosion of stainless steel and has started to be applied across several offshore facilities. There is potential for large long terms savings by using a barrier wrap coating to arrest corrosion on piping rather than replacing. Long term testing using barrier wrap coatings to arrest pitting corrosion is ongoing. Newly approved alternative coating materials, such as Humidur, will be tested in 2020.
Finalised how Bayesian Networks can be used as the modelling and reasoning engine in a risk management tool on two case studies: Pipeline Walking and Umbilical Control system. Final report and public version of main findings to be submitted as research paper in 2020. Discussions were held with Woodside staff to explore possible applications of the Bayesian methods for modelling strategic and cumulative risk.
Seismic data processing
Generative adversarial noise attenuation (GANA) network built for seismic data processing. Focused on 2D shot records, i.e. one source firing into one cable by: First proposing a novel version of a generative
adversarial network (GAN) that can decompose the challenging estimation of a high-dimensional distribution into the simpler estimation of multiple 1D distributions. Designed and developed a GAN for synthetic 2D seismic data, and showcased the feasibility of using it for real 3D seismic data processing. Plan for 2020 is to extend GANA to the 3D scenario by leveraging recent advances in volumetric convolutional networks and generative adversarial nets.
Process plant re-start visualisation
Investigated the application of visualisation tools for planning and communicating rapid execution of process plant trip recovery. Reviewed the existing material and performed background research on existing software packages. Implemented a prototype user interface that supports Program Evaluation Review Technique (PERT) charts and uses the webcola library (constraint-based graph layout library) to automatically layout these charts based on the PERT node dates. Visited Perth to show the results using initial recovery data.
