Diving Maintenance


Submerged assets are often situated in harsh environments conducive to corrosion and degradation and just like terrestrial structures they require periodic maintenance to ensure reliable performance and prolonged asset life.

Fremantle Commercial Diving specialises in developing multi-year subsurface maintenance programmes, and currently maintain these for some of the largest organisations in the world.

Typical subsurface maintenance tasks include:

  • General inspection
  • Cleaning
  • Water blasting
  • Anode change-out
  • Dredging
  • Corrosion protection
  • Pile remediation
  • Component change-out

When determining our client’s inspection and maintenance needs, we consider a broad range of factors before recommending a course of action.

These factors include:

  • Construction material of the asset
  • Length of time since the asset was last assessed
  • Possible wear points on the asset
  • Time constraints for the job
  • Budgetary constraints for the job
  • Legislative implications for the task
  • Insurance considerations

A clear plan of what can be achieved for the client is then formulated incorporating the most relevant diving and ROV techniques. When maintenance is complete, data is assimilated and delivered in a clear and meaningful format.
