Woodside to create a new offshore inspection system

Australian company has collaborated with industry to create an offshore caisson cleaning and inspection tool (CCAIT system) that allows remote inspection of critical equipment on its offshore platforms

Woodside announced that the CCAIT system incorporates a human-sized robot, designed to inspect the inside of caissons – vertical carbon steel pipes up to 70 m long and up to 1.2 m wide – which are used on offshore platforms to house critical equipment such as firewater and seawater lift pumps.

Woodside Executive Vice President Technical Services Daniel Kalms said:
  • The CCAIT system removes the costs of mobilising tools from international locations, including the cost of delay in fractured supply chains
  • These can represent up to 50% of the total cost of an inspection campaign
The new system was designed, developed and deployed in less than 12 months via a collaboration led by Woodside and incorporating Perth-based expertise from Nexxis, Monadelphous, WOMA and Fugro.
Nexxis Technology CEO Jason de Silveira said:
  • Woodside's decision to partner with a local company demonstrated the strong sovereign capability of Australia's advanced manufacturing sector to develop and deploy cutting-edge robotic technology
The CCAIT system is remotely controlled from a safe location on an offshore platform by skilled technicians.
The tool is lowered inside the caisson via a tether and winch arrangement.

Wheels are then extended to centralise the tool within the caisson, and probe arms extend to enable ultrasound inspection.
A series of high-definition cameras stream video back to the technicians, with the data used by the asset team to define the forward plan.

Woodside recently completed its merger with BHP’s oil & gas business, becoming a top 10 global independent energy company by hydrocarbon production and the largest energy company listed on the ASX.
