Asset Integrity Management:

Simply put ‘AIM’ means “having a strategy to get the most out of your asset in a safe and efficient manner, whilst lowering the associated cost. It is a tactical plan for managing an organization’s assets to deliver an agreed standard of service. Typically, an asset management plan will cover more than a single asset, taking a system approach – especially where a number of assets are co-dependent and are required to work together to deliver an agreed standard of service.

Dropped Objects Survey:

By identifying objects that are at risk of falling from the derrick or other raised structures, such as nuts, bolts or lifting points etc. that are improperly added to structural members, we can reduce potential hazards. Dropped objects are an all too common occurrence and simple procedures and vigilance can significantly help reduce these. In the interests of reducing risk we have seen the dropped object surveys broaden its remit in recent years to now cover the whole installation, and our surveys have evolved to cover all of the relevant areas for you, to the extent that we now offer one of the most comprehensive services available. We have however, retained our approach to these inspections as being as practical and pro-active to ensure that we solve as many issues as possible on site, so as to reduce or eliminate the amount faults/ failures in the report and to reduce items to be attended to going forward.


Masts and derricks support enormous loads when drilling and running casing, 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. A comprehensive review of all items in the derrick and sub-structure with the potential to become dropped object based on a sequential review of all likely well operations to be carried out (drilling, casing, wire lining, etc.) a task analysis is conducted with each item of equipment required for each task being identified and its position within the derrick and substructure. Sub-divide the derrick and sub-structure into manageable areas for inspection.

CATEGORY 1: Conducting daily observation of the mast/derrick and substructure during operation to determine indications of inadequate performance.

CATEGORY 2: Includes a thorough inspection of load-bearing areas, including sheaves, for cracks, damage, corrosion, loose or missing components and premature wear.

CATEGORY 3: Inspections focus on load-bearing components and members to determine the condition of the mast/derrick and substructure. CATEGORY 4: Inspection, and cleaning required to conduct NDT of all defined critical areas. All welds are being visually examined and welds in critical areas should be inspected using magnetic particle or liquid penetrant method.
