• API RP 4G Derrick, Mast & Substructure Inspections
Masts and derricks support enormous loads when drilling and running casing. API-recommended practice for mast and derrick inspections is a critical element to avoiding potentially non-productive time or even serious incidents and catastrophic events during drilling operations or following rig reactivation.
Sources Technology Co. offers full API 4G derrick inspections in line with API-recommended practice. API-recommended practice 4G has established four categories for drilling and well servicing structure inspections and sets forth personnel qualifications for these inspections.
CATEGORY ICategory I inspections are carried out by general rig personnel conducting daily observation of the mast/derrick and substructure during operation to determine indications of inadequate performance.
CATEGORY IICategory II inspections are performed by personnel having adequate experience and knowledge in masts/derricks.
CATEGORY IIIOur Category III inspectors are in possession of a recognized degree, certificate, or professional standing, or who by knowledge, training, or experience have successfully demonstrated the ability to resolve problems related to the subject matter or work in question.
