CODA Launches First Online Training Module

The Centre of Decommissioning Australia (CODA) has launched its first online training module, Introduction to Well Decommissioning, expanding access to foundational decommissioning knowledge across the industry.

Developed in response to strong demand for CODA’s in-person training, the new self-paced module provides a flexible learning option for those unable to attend the in-person Introduction to Decommissioning course, as well as individuals and organisations looking to build capability for themselves or across their teams.

The module explores the well lifecycle, with a focus on plugging and abandonment, covering key steps, regulatory frameworks, and planning considerations that support safe, responsible, and cost-effective outcomes.

Content has been developed in collaboration with Chris Wilson of Labrador, a Subject Matter Expert who also delivers this material as part of CODA’s in-person course.

The online module also marks the introduction of the CODA Academy, which brings together CODA’s in-person training and online learning. While in-person courses will continue to run, the Academy expands how participants can engage with decommissioning training delivered by CODA.

CODA CEO Francis Norman said:

“The launch of our first online module is an important step in how we support the development of the decommissioning industry.

We know not everyone can attend training in person, so the CODA Academy allows us to expand how we support capability development across the industry, while continuing to deliver our in-person courses.

By combining in-person training with flexible online learning, we are creating more pathways for industry to build capability, particularly as the scale and complexity of decommissioning activity continues to grow.

Building online content also allows for just-in-time and very focused learning across the industry”

The learning experience has been developed in partnership with local, Perth-based organisations, with Sentient Computing delivering the eLearning platform and Of Note Designs designing and developing the web environment.

Additional online modules will be released over time, forming a broader learning pathway across the decommissioning lifecycle and complementing CODA’s existing training.

Major Milestones Reached in Harriet Alpha Decommissioning

CODA recently participated in a site visit to the Harriet Alpha assets following their arrival at the Australian Marine Complex (AMC) in Henderson, providing an opportunity to observe progress on the offshore removal and onshore dismantling phases of the project.

The visit brought together representatives from CODA, Santos, Liberty Industrial, McDermott, and the Department of Energy and Economic Diversification. Attendees were provided with a detailed walkthrough of the offshore removal and onshore dismantling workflow, including load-in operations and the transfer of large structural components from barge to self-propelled modular transporters (SPMTs) for positioning within the laydown area.

Harriet Alpha, installed in 1985 and ceasing production in 2013, was a pioneering development in Western Australia’s offshore oil and gas industry and forms part of a broader decommissioning program across the region. Liberty Industrial was engaged by Santos to undertake a deconstruction and disposal study for the Harriet Alpha platform. Following the award of the engineering, procurement, removal and disposal (EPRD) scope to McDermott in 2024, Liberty Industrial partnered with McDermott in 2025 to deliver the safe receival, demolition, recycling and disposal activities of the retired platform, including the helideck, topsides, jacket and associated equipment.

With major components including the jacket, topsides and the “Pancake 4” section weighing approximately 1,480 tonnes, 1,440 tonnes and 185 tonnes respectively, the project achieved multiple milestones, including being the largest offshore platform removed from Australian waters at the time.

The Harriet Alpha decommissioning scope represents a significant example of the growing capability of the Australian offshore decommissioning sector. It sets a new benchmark for scale and execution, and reflects the progression toward a growing number of large-scale decommissioning programs across the industry.

CODA acknowledges and congratulates all project teams involved in delivering this stage of the work.
