About the operation

AOS Offshore was approached by the Vopak Innovation team in Singapore to come up with a diverless solution for inspection of their jetty piles.

Vopak has as a worldwide HSEQ goal to replace all exposed manual labour with more safe and efficient methods using new technology.

Here’s what we did

AOS offered a diverless using mini subsea drones, heavily modified to perform following services:

  • Full visual HD inspection of all piles and anodes
  • Wall thickness reading using Pulsed Eddy Current technology (no cleaning of piles)
  • Cathodic Protection measurement of existing anodes and functionality
  • Real time laser measurement technique to verify remaining service time of anodes

The Outcome

The final outcome resulted in a fully inhouse developed Subsea Drone fleet to perform the above tasks to the standard and approval from Vopak Innovation.

Number of Divers in the water: 0

Infrastructure Downtime: 0

Visual and NDT Inspection Completed: 9 Days

More cost-effective than conventional inspection with divers

We thank the Vopak Innovation team for believing in AOS and our capability to meet their challenge and are looking forward to new future challenges.
