Inspection without staging, without entry, without risk
Tell us the vessel, the port and the window. Scoped reply, usually the same working day.
The most dangerous part of a traditional close-up survey is not the inspection — it is getting a person to the inspection point. Staging in a ballast tank, entry into an oxygen-depleted void, or working at height in a cargo hold carries risk that the inspection itself does not.
Remote inspection technology removes that exposure. Confined-space drones, magnetic crawlers and ROVs deliver high-resolution imagery and thickness readings from structure nobody has to reach, and classification societies increasingly accept RIT in place of conventional close-up survey for defined scopes.
What is included as standard. Anything outside this is quoted separately and flagged before mobilisation, never added afterwards.
Collision-tolerant drones survey ballast tanks, cargo holds, voids and chain lockers, producing high-resolution imagery of structure at height.
Magnetic crawlers take ultrasonic thickness readings on shell plating and structure without staging or rope access.
Remotely operated vehicles inspect flooded spaces, sea chests and underwater structure where diver access is impractical.
Imagery and readings are processed into a located, indexed record so findings can be tied to specific structural members.
Live feed to the attending surveyor, with the ability to revisit any area on request during the inspection.
We confirm with the society that RIT is acceptable for the intended survey scope before it is relied upon.
Spaces are ventilated, lit and confirmed suitable for equipment deployment.
Equipment is flown or driven through the planned inspection programme with live monitoring.
A located, indexed report with imagery, readings and findings is issued for the class file.
Blue Wave Classification Ltd. (BW Class)
Firms engaged in survey using Remote Inspection Techniques (RIT) as an alternative means for Close-up Survey of the structure of ships and mobile offshore units.
Yes. Blue Wave Classification (BW Class) approved Cleanship Marine Services FZE as a service supplier for survey using Remote Inspection Techniques as an alternative means for close-up survey of the structure of ships and mobile offshore units — certificate BW/096439, issued in Dubai on 23 July 2026 and valid until 23 July 2029.
For many scopes yes, but acceptance is scope-specific and remains the society's decision. We establish it in writing before the survey rather than presenting a report and hoping.
Some platforms carry UT probes, but for reliable gauging on structure we generally prefer crawlers or conventional technicians, using drones for visual assessment and to target where gauging is actually needed.
Tell us the vessel, the port and the window. You get a scope, a crew size and an honest duration — usually the same working day.
