View Full Case StudySubsea Global Solutions is able to supply a range of remotely operated vehicles to meet the inspection demands of clients where water depth, bottom time and or hazardous situations mandate the use of non-manned intervention methods.
A number of these vehicles are small and lightweight and can generally be operated by two persons out of a small boat or from the land.
ROV operations are particularly well suited to deep or hazardous applications of an observational only nature.
ROV’s are also often used for:
The vehicles can be fitted with high resolution color cameras, acoustic navigation systems and manipulators for basic operations such as small object recovery, sample collection and basic rigging.
Subsea Global Solutions is able to offer a range of Ultrasonic testing services including thickness testing using both digital and "A scan" equipment along with full weld inspection using angle beam probes.
M.P.I can be provided for surface crack detection using dedicated equipment employing direct and indirect magnetization systems. Surface preparation of the test pieces is also part of the service and ranges from high pressure water blasted surfaces, abrasive grit blast or machined finishes. Personnel hold both national and international inspection qualifications with an extensive background in offshore and onshore surveys of structures and components.
General inspection tasks are supported by High Resolution Color Video equipment which utilizes the latest digital image enhancement technology.
Real time monitoring at the surface enables clients to observe the video and direct the works as required.
These images can then be stored to conventional USB drives or made available through electronic media directly to the client's office.
Still photography systems using digital underwater cameras provide a range of photographic presentations including photo-mosaics, overall wide angle, and macro photography. Detailed inspection reports and CAD drawings are provided.
