Class Survey

RAI is accredited by ABS for performing hull thickness gauging as part of special periodic surveys for mobile offshore drilling units, fixed offshore structures and other marine vessels such as crude carriers.


RAI uses highly trained and experienced IRATA technicians, that use rope access techniques that are extremely safe and efficient alternatives to traditional survey methods such as rafting or scaffolding. RAI can carry out the work while the vessel is sailing, on tow or when docked during scheduled shipyard visits.


RAI is experienced in all aspects of reporting for the classification societies and provides final reports in both soft and hard copy formats.

We understand the importance of collecting the right data in the right way. Our personnel have the necessary experience in all aspects of special surveys.
