Underwater Inspection

Dive Marine Services – Underwater Ship Inspection, ROV and Survey Services

Our  inspection divers are adept in identifying and visually assessing for structural deterioration and damage,  and the overall condition of ships and other subsea structures such as terminals, jetties, piers, berths, modus and platforms.  Our methods include:

General underwater Visual Inspection: still colour photography remains a commonly used and relatively inexpensive method which produces a permanent, detailed record of an asset’s condition. This is carried out by a team of divers.  

Close Visual Inspection: this is a more detailed inspection of a component or specific section of a structure to ascertain if there are defects such as physical or corrosive damage, or weld cracking  This is conducted by a dive team and requires thorough SA standards cleaning.  

Underwater Closed Circuit Television and Videography: the use of CCTV and video have become an essential tool  in most underwater inspection operations and in-water surveys for dry dock extension. This approach gives us better overall information  and has the advantage of providing real time viewing during or after the inspection. “Live” communication and visuals between the client representatives and our divers can be maintained throughout the inspection.  This important two-way communication means the client and divers can work in sync to identify and collectively address any issues, and have a permanent record of the entire process. 

Remotely Operated Vehicle (ROV): ROVs are manned by ROV pilots which are highly maneuverable underwater robots that allow us to understand what is happening under your vessel with minimal diver intervention. ROV inspection allows ship owners to proactively manage maintenance, fuel efficiency and security to determine optimal cleaning and paint schedules.  

Without needing to deploy dive teams, ROV inspection leads to a safer process with unnecessary down-time or lifting the boat out of water.  It also becomes easy to access and inspect areas that might be too small for divers. 

Specialised Ship Inspection and Surveys: these includes hydraulic surveys, magnetometer surveys, side scan surveys and multibeam ultrasonic surveys.
