Offshore decommissioning

A CBS Executive Education Masterclass

Offshore Jack Up Rig in The Middle of The Sea

Learn all aspects of decommissioning of offshore facilities from global leaders in the field.

In this masterclass, you’ll rapidly upskill your knowledge of offshore decommissioning in Australia, and delve deeply into the legal requirements and the processes involved. You’ll also look at the restoration processes and factors to consider during planning.

You’ll study nine 1.5-hour modules online in your own time over the course of four weeks, followed by a half-day face-to-face session, which includes expert presentations and a panel discussion with the opportunity to ask questions and network.

The masterclass will be delivered by Curtin Business School and the Curtin University Oil and Gas Innovation Centre with industry experts, ensuring you’re learning the latest insights, evidence-based research and data, and gain expertise in global best practice.

When you complete this course, you can choose to study further, and will receive 10 credit points towards Curtin’s flagship MBA, Graduate Certificate in Business, Graduate Diploma in Business or MBA (Advanced).

Mr Dean Stewart is an engineering manager and executive with 30+ years’ experience in the oil and gas industry covering all aspects from consulting, contracting to managing operating/non-operating oil and gas companies in key leadership roles. At present, Dean works as an independent consultant focusing on decommissioning with expertise in decommissioning programme management, technical evaluation of decommissioning options, comparative analysis, commercial/economic evaluations, and regulatory compliance.
His recent achievements include the technical management of multiple aging North-West Shelf assets as a non-operating foreign National Oil Company based in Perth, Australia. This involved the evaluation of the economic life and regulatory decommissioning requirements along with detailed technical assessment and scoping of the decommissioning execution strategies and comparative assessment evaluations.
Professor Grantley Taylor holds a Bachelor of Science (Honours) from the University of Adelaide, a Bachelor of Economics from University of New England and a PhD in accounting from Curtin University.
From 1990 to 2003, he worked in the mining industry where he was in charge of multi-million dollar exploration and advanced resource projects. From 2003 to 2006, he worked in the Energy and Resources sector at the Australian Taxation Office. In 2006, he joined Curtin University where he conducts research in the areas of international tax avoidance, sustainability, governance, and capital markets.
Mr Christopher Murphy has over 41 years experience in the oil and gas business and has extensive knowledge of well construction and decommissioning, and small offshore facilities decommissioning. Christopher was previously the Head of Wells and Production Technology for British Gas and Vice President – Global Marine Solutions for Wild Well Control.
