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 :
