Oil & Gas Sector Inspections :

The oil & gas industry, also known as the petroleum and natural gas industry, includes the global processes of exploration, extraction, refining and transporting of petroleum and gas products.

Oil and gas industry operates according to stringent standards that primarily strive to keep equipment running efficiently while maintaining workplace safety. Conforming to such standards is challenging because oil and gas operations involve drilling (both on land and offshore), reservoir engineering, well servicing, production services, refining and transportation of petroleum products, and many other operations.

Not only is it challenging to conform to industry standards, but it is expensive to maintain a safe workplace and to protect workers from harm. It is necessary to equip workers with protective apparel; to continually train them on practicing safety procedures; and to keep them up to date on practicing improved equipment inspection techniques.

Offshore & Marine Inspections:

LIA is a Registered and Approved company in India and Globally to perform inspections of Ships , Boats and Vessels inspected for safety before the Ship/Boat or Vessel is put into service or on first registry and annual inspected thereafter.

Should an accident occur which affects the safety of the ship or important repairs be made then the ship is required to be inspected to ensure its seaworthiness. LIA - National safety inspection certificates for All Ship/Boat or Vessels are required to be renewed annually.

A ship can be inspected by Authorised Marine Surveyors of the LIA or by any LIA Authorised Sub Agents.


Oil Rigs or Oil platform or Offshore platform is a large structure with facilities for well drilling to extract and process oil and natural gas, or to temporarily store product until it can be brought to shore for refining and marketing. In many cases, the platform contains facilities to house the workforce as well.

Depending on the circumstances, the platform may be fixed to the ocean floor, may consist of an artificial island, or may float. Remote subsea wells may also be connected to a platform by flow lines and by umbilical connections. These sub-sea solutions may consist of one or more subsea wells, or of one or more manifold centres for multiple wells.
