A UK‑based marine contractor required an inspection of an ageing subsea valve structure within a port environment after signs of failure were identified. The valve assembly, originally installed many years prior, had deteriorated significantly due to prolonged saltwater exposure, corrosion, and mechanical fatigue. Before any repair or replacement strategy could be planned, the client needed a clear, safe, and high‑quality visual assessment to understand the extent of the damage.
With diver access deemed unsafe due to limited acess, the contractor partnered with HydroView Marine to carry out a detailed ROV inspection of the subsea valve.
The structure’s age, condition and limited acess presented several critical concerns that required verification:
The inspection needed to be completed without disturbing the structure, making ROV deployment the safest and most effective approach
The inspection of the subsea valve was completed safely and efficiently using HydroView Marine’s BlueROV2 system. High‑clarity visuals and close‑proximity manoeuvring allowed the client to fully understand the extent of deterioration and structural failure without exposing personnel to danger.
This project demonstrates how ROV technology provides essential clarity when ageing or compromised subsea infrastructure cannot be safely accessed by divers. The resulting data supported informed decision‑making around repair and replacement — reinforcing the value of ROV inspections for both operational and environmental priorities.
