Survey & Inspection

SeaTec provides a number of above water and subsea surveying services.


Under water inspections in lieu of dry-docking (UWILD), or in water surveys (IWS), are required to ensure the structural and operational integrity of a marine asset throughout its operational life span. Completing these surveys with divers, while on location, saves the asset owner and their clients both time and money by reducing downtime, limiting time off-contract, and reducing or eliminating the need for expensive and limited dry-docking. This process includes sub-surface inspection utilizing divers and a top-side inspection utilising rope access technicians as required.

  • Sales Surveys
  • Sea Valve /Chest Inspections
  • Extension to dry docking
  • In-Water surveys in lieu of dry docking

  • Eddy current Inspections
  • ROV Inspection (portable and fly away)

Recommended Periodic inspection is a routine inspection carried out at pre-determined intervals. It applies to existing installations to verify that they are being maintained (the effects of deterioration and/or change are being monitored) within an appropriate specification for continued use. Please be advised the intervals between periodic inspections should not exceed three years. However it is recommended to carry out these surveys on a more frequent basis.
