In 2019, the decision was made to use a helicopter to remove the North Rankin Alpha HP Flare tip. The helicopter lift required careful planning, preparation, a custom-designed ultra-lightweight scaffold system capable of holding 2.5 Tons, handrails made of fibreglass, and the implementation of a custom lifting davit.
NRC HP & LP Flare Tip Change
The main purpose of this project was to replace the HP & LP flare tips on the North Rankin Alpha site – with a focus on minimising plant and personnel risk, as well as completing the work quickly, safely, and efficiently.
Vertech Group were contracted to provide temporary rope access platforms to assist with the flare tip replacement using their equipment and expert team.
Vertech provided a suite of project management, engineering and planning services, including supporting the sequencing, lift planning, HAZIDs, work pack preparation and procurement.
A replica flare structure was erected in the Vertech training facility for mock trials to be run to ensure maximum efficiency for the execution phase. The simulated training allowed us to identify several efficiencies and potential risks that we were able to remove before implementation during a short shutdown window.
Vertech’s rope access solutions were critical in this process, being able to erect the appropriate scaffolding platforms at the flare tip and at the base as per requirements.
These platforms were able to be erected and deconstructed with minimum interference from the rest of the site, allowing the project to continue unperturbed.
The Schedule Recovery performance of 58.5hrs shown below is an impressive effort from the Vertech Team, given the late start.
It becomes even more impressive when we consider the fact that we have experienced 33hrs downtime due to Weather Conditions during this scope.
If this had not occurred, the team would have delivered RFSU only 20.5hrs ahead of the baseline finish date after being 112hrs late in starting.
During their downtime, the Vertech Team have effectively delivered the implementation of the Flare Bellows scope for the TA Team which has been a challenging project in and of itself
Pleasingly this also represents the safe and successful completion of all Brownfield Projects Turnaround Scopes.
A Job very well done by the boys.”
