Customer needs
A LNG (Liquified Natural Gas) company needs to inspect some oil separator vessels and various tanks on one of their main LNG plant. There are manholes but they want to avoid any man entry into confined space. Some nozzles have been identified but they are 50 mm to 100 mm diameter. Vessels and tanks size vary and are up to 10m high and 5 m diameter.
Rvi Inspection purpose is to check presence of any foreign object, state of internal surfaces, presence of corrosion and welds conditions.
There are two challenges :
- To find a compact enough camera for smallest nozzles (50 mm).
- While having sufficient lighting for oil and gas inspection of bigger vessels.
The solution : Visioprobe remote inspection camera
- Visioprobe equipment for oil and gas inspection
- Pan & Tilt 45 mm for small nozzle tanks, 90 mm zoom camera for bigger tanks
- Control Unit
- 15 m flexible cable
- Centering device
All inspections could be performed in a timely manner with the same range of products. The image quality was excellent in all conditions and allowed for a complete check of asset integrity.
The product ease of use and its robustness also meant that several operators teams could share one equipement with no damage and no additional training. The product was bought by the LNG plant operator and its specifications were also shared with all inspection companies involved on the plant.
/// All inspections performed in a timely manner
