Dropped Object Surveys and Inspections are a key element of dropped object control and prevention management systems. Rig personnel regularly perform dropped object inspections as part of routine maintenance and operational activities.
IES offers large scale Dropped Object Survey to complement the rig dropped object prevention inspection program. The survey provide added assurances that all potential dropped object hazards are identified, assessed and recorded such that control measures and corrective actions can be recommended and implemented.
