The North Rankin redevelopment is the largest offshore project yet undertaken in the North West Shelf offshore area, with significant structural upgrades required to the North Rankin ‘A’ gas platform, in readiness for the construction of a completely new platform known as the North Rankin ‘B’. Once complete, two bridges, both approximately 110m long would connect the NRA and the NRB. Safehouse Habitats task was to supply multiple habitats, over a 27 month period, to allow for varied and complex construction and hot work to take place, with minimal impact to ongoing production of the NRA.
