Unit Overview


This unit provides a broad introduction to aspects of decommissioning offshore infrastructure. The unit addresses offshore decommissioning across engineering, marine science, economics, societal perspectives, health and medical science, and governance. The unit is delivered in intensive mode across six sessions, each covering offshore decommissioning from a particular discipline perspective. It explores (1) engineering—options for decommissioning, covering complete removal to augmentation of infrastructure decommissioned in situ with engineered artificial reef modules and smart engineering in design for future decommissioning; (2) marine science—positive and negative impacts of the various decommissioning on different marine environments; (3) economics—direct and indirect costs and modelling approaches of decommissioning options to oil and gas operators and to nations; (4) societal perspectives—marine heritage and interactions between ocean users, coastal communities and the broader public with policy makers and the effects on society; (5) health and medical sciences—effects of decommissioning decisions on seafood abundance and sustainability and the role of marine corals in biomedical sciences; and (6) governance—the role of law, policy and governance in facilitating decommissioning options and protecting the marine environment, ocean users and a competitive investment climate for oil and gas producing nations.

6 points

Students are able to (1) demonstrate a basic knowledge of offshore decommissioning options; (2) display a high-level of understanding of the effects of different decommissioning options on different marine environments; (3) critically analyse and make economic arguments for different decommissioning options for different scenarios; (4) demonstrate an appreciation of the interactions of different community groups and policy makers with relation to decommissioning options; (5) display a high level of understanding of the direct and indirect health benefits of different decommissioning options; (6) critically analyse and make legal arguments for different decommissioning options for different scenarios; and (7) demonstrate an appreciation of the interdisciplinary nature of offshore decommissioning between the engineering, biological, social and health sciences.


Indicative assessments in this unit are as follows: (1) in-class assessment; (2) project; and (3) presentation. Further information is available in the unit outline.

Student may be offered supplementary assessment in this unit if they meet the eligibility criteria.

To be advised
  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
  • Contact hours provide an indication of the type and extent of in-class activities this unit may contain. The total amount of student work (including contact hours, assessment time, and self-study) will approximate 150 hours per 6 credit points.
