Mechanical Integrity – Static Equipment

Ankaa Consulting are well experienced in developing inspection plans for static equipment utilising RBI methodologies in accordance with API 580/581 for onshore plant and DNV-RP-G101 for offshore topsides equipment. Typical facilities that can be considered include:

1) Onshore facilities – gas processing, receiving facilities, & LNG.

2) Offshore facilities –FPSO, production & wellhead platforms

3) Petrochemical Plant – Oil Refinery, NH3, Urea, Methanol, Nitric Acid, tank farms, etc.

Inspection methodologies applied following RBI assessment are consistent with the requirements of API 510 / 570 / 653 as appropriate. Written schemes of examination (WSE) are typically developed for the assets concerned.
