Offshore Decommissioning
We have been supporting Australia’s offshore oil & gas decommissioning program since 2017.
During this time, we have completed many varied projects and assignments that have utilised the skills and expertise of our
multidiscipline engineering team.
Our experience extends across numerous assets, each unique or nuanced in their own way, allowing us to continually build our knowledge
and capability as we progress from one assignment to the next.

Capability Synopsis
With five years of experience supporting offshore oil and gas decommissioning programs in Australia, we have developed insights, capability
and skills that are unparalleled in the Australian market.
This capability extends from office based planning/engineering activities through to field (offshore) activities. We are very
familiar with the safety and logistical requirements of offshore work, having worked on around ten different platforms during our
various assignments.
Some of the activities we have undertaken include:
-
A nine-month multidiscipline project (FEED and detailed design engineering, installation, and commissioning) that reconfigured various
piping, electrical and instrumentation systems across 3 offshore installations, thus allowing decommissioning plans to proceed.
-
A 12-month assignment scoping the decommissioning options for an offshore installation at cessation of production including engineering
down, cleaning, air gapping of piping between modules, utility and power requirements, ongoing maintenance needs, ongoing safety and
communication systems, access to and from the installation and module dismantling and removal options.
-
A 6-month assignment assessing heavy lift vessel (HLV) removal options including preparations required on the offshore installations
(such as cleaning, module air gapping) to facilitate the HLV program.
-
An 18-month assignment which included the preliminary engineering down of platforms transitioning from a production to non-production
status, requiring extensive management of change upgrades, maintenance rationalisation and various systems re-design for non-manned
operations.
-
A 6-month assignment preparing the overall roadmap for the removal of several offshore installations including preparations for
cessation of production, well plug and abandonment, management of change, regulatory management, mothballing/preservation, platform
de-staffing and safety requirements.
-
An engineering study to advise on the safety requirements and activities required for an offshore installation to be put into a low
maintenance (care and preservation) mode.
-
Development, over a two-year period of a first-in-kind digital database tool, iTopDecom, to assist in the decommissioning/systems
management of complex assets such as offshore oil & gas installations.
With our capability we look forward to continuing to support Australia's offshore decommissioning program for many years.
