We invite you to attend our August Evening Technical Meeting.

Collaborative Technology Deployment – Julimar Development Phase 2 Project

Date: Wednesday, 17 August 2022

Time: 5.30 – 8.30pm AWST

Venue: Parmelia Hilton Perth

---

The evening will focus on the following three topics:

Technology Deployment

Presented by Ben Witton – Woodside

Project delivery certainty is a key success factor for positive business outcomes.  Taking on world first applications across multiple delivery streams comes with risk that requires significant risk reduction to meet business requirements.  The Jumilar Development Phase 2 completed this successfully across both drilling and completions and subsea construction.

This presentation discusses contracting, design, execution, and evaluation of technologies for the subsea construction of the Julimar Development Phase 2. It includes methodology followed for both technology selections, engineering development, qualification tests, post project evaluation, lessons learned along with health and safety benefits.

Technology Innovations

Presented by Michael Salsano- Subsea 7

Several innovative technologies were implemented during the execution of the Julimar Development Phase 2, including the largest CRA insulated flowline ever installed via reel lay, the use of Thermoplastic Composite Pipe for a MEG jumper application, and the use of Pipe Clamping Mattresses for walking mitigation.

This presentation provides an overview of these novel solutions and of the benefits they can offer. It also discusses the challenges encountered and the focus areas that were identified during design, construction and installation phases of the project.

Understanding PCM-seabed interaction through physical modelling

Presented by Phil Watson & Scott Draper – UWA Centre for Offshore Foundation Systems

Deployment of pipe clamping mattresses for Julimar Development Phase 2 represents the first use of this technology in carbonate silty sand often encountered in intermediate water depths on the North West Shelf – introducing challenges related to geotechnical performance and sediment mobility.  To address these challenges, physical modelling was undertaken in the both the centrifuge and large O-tube facilities at UWA.  This presentation will provide an overview of the testing that was performed, summarise key findings, and preview ongoing studies.

The Society for Underwater Technology invite you to the April 2022 Evening Technical Meeting:

DECOMMISSIONING

 

The evening will focus on the following three topics:

Innovative Rig Solution for Well Abandonment
Chris Wilson – Labrador (Via teams)

The world is currently going through a surge in offshore oil and gas facility decommissioning. A lot of this work involves abandoning wells, and we know that NOPSEMA is closing in on operators to clean up the seabed. Unless the industry gets innovative, this has the potential to cost the industry and the taxpayer a lot of money. As the saying goes “If we always do what we always did – we will always get what we always got!” For the first time ever – Australia will have access to a semi-submersible intervention rig that will facilitate cost effective well (and subsea infrastructure) abandonments. For this to work – we need to change our thinking on how we abandon.

 

Research examining the value of Australia’s oil and gas infrastructure for marine life
Dianne McLean – Australian Institute of Marine Science (via teams)

An assessment to remove, partially remove, leave in situ or repurpose oil and gas infrastructure at end of field life can be more robust if it uses rigorous, relevant and accurate data. We use industry remotely operated vehicle (ROV) video, specialised high-definition stereo-video systems, and partner with industry to enhance offshore research campaigns for the collection of scientific data from infrastructure. Here I provide an overview of the latest research findings and identify critical focus areas where research is required to assist decommissioning decisions and advance our understanding of the influence of oil and gas infrastructure on Australia’s marine ecosystems.

 

Terminator Wellhead Severance
Michael Lewis – Baker Hughes

Baker Hughes has launched a new mechanical subsea wellhead cutting system that can be launched from a vessel of opportunity with minimum preparation time. The ability to cut in any water depth from a vessel is a major step forward in wellhead removal. The system which utilises proven mechanical cutting technology to cut and remove subsea wellheads has been extensively tested onshore prior to its first offshore deployment last year. Since the system requires minimal equipment, is quick and easy to mobilise and can be deployed at any water depth it can reduce subsea wellhead removal costs significantly. Thirteen wellheads with 4 customers in seven campaigns have been removed by the Terminator in the first 16 months of operation.

Powerful avalanches of sediment, known as turbidity currents, sculpt deep submarine canyons and create the largest sediment accumulations on our planet. Such flows can travel at fast speeds (up to 20 m/s), over thousands of kilometres, transporting vast quantities of sediment, organic carbon and pollutants to the deep sea. Their powerful nature means that these flows can damage important seafloor infrastructure, such as cables and pipelines, as well as sensors placed in their path to measure them. We have therefore largely had to rely upon the deposits these flows left behind, or scaled-down laboratory experiments, to infer their behaviour. However, the past few years have seen an explosion in direct measurement of turbidity currents, including the first source (river) to sink (deep sea fan) field campaigns, which is transforming our understanding of these dynamic deep sea events.

This presentation will highlight some of the novel and emerging technologies used to successfully monitor turbidity currents in a range of systems worldwide by a large international collaboration, shed new light on their field-scale behaviour, and share lessons learned from recent instances of infrastructure-damaging flows, such as the recent 1200 km runout flow in the deep-water Congo Canyon that damaged multiple seafloor cables during the 2020 COVID-19 lockdown.

About the presenter:

Dr Mike Clare, Principal Researcher in Marine Geohazards, National Oceanography Centre, UK

Dr. Clare leads the Marine Geosystems research group at the National Oceanography Centre. He has published >60 peer-reviewed papers focused on sediment and pollutant transport, offshore hazards, and application of novel monitoring techniques to assess threats to coastal communities and seafloor infrastructure. His research tackles questions such as the implications of future climate change for natural hazards, how new technology can be used to make direct measurements of powerful seafloor hazards, and monitoring deep-sea pollution. He formerly worked at Fugro as an engineering geology and geohazards consultant, and is currently the Marine Environmental Advisor to the International Cable Protection Committee. He regularly provides expert advice to a range of offshore infrastructure industries and policy-makers about threats posed by offshore natural hazards and environmental interactions with seafloor infrastructure.
