Derrick MAST survey
A quick search of the internet will present you with a whole variety of different companies offering to undertake these inspections for you. You don’t have to look too deeply to realise that most of these are either unqualified, lacking the relevant product knowledge or experience therefore hiding these facts with words and reference to specifications to distract you from the fact that they are simply not qualified.
The facts remain that unqualified companies and/or personnel increase the risk to your operations where as ZENGARY represents both a reduction in risk and a positive move toward a safer working environment.
Derrick/mast related incidents on land rigs and offshore derricks still represents an unacceptable amount of oil rig accidents, which is not helped by untrained or inexperienced personnel and companies inspecting drilling derricks.
The API approved course that ZENGARY has developed and successfully implemented now provides the industry with the standard with which to move forward and further improve the safety statistics of derrick related incidents.
ZENGARY carries out API 4G Cat III & IV Inspections all over the World on a day to day basis.
