OES inspection reports are compiled with the inclusion of substantial photographic and visual references making it easier for post inspection work to be completed. Core sections are also made available online at where the client can securely log in, access, interact with and update certain sections of the report. In addition also enables clients to:

View and search all visual, test, MPI and corrective action registers
View quarantined and rejected registers. View the corrective actions register (CAR); which highlights all major findings during the Inspections, as well as allowing the CAR to be updated to its current status, which acts as centralised “live” document between those involved; for example the Rig Manager (offsite) and the rig personnel (onsite).
Create lists of equipment added to or removed from the rig site.
Download a copy of the report.

OES has become industry renowned for its accurate, intuitive and detailed reports which provide practical tools for clients to utilise in working towards improvements in safety and efficiency. We understand that providing the best report we can, gives our clients the best tool to implement improvements. We also know that information is only of use if clients can find what they are looking for and easily interpret our findings, therefore OES’ reports are laid out in a manner that our clients have had as much say in as we have.

We know that each rig is an individual operation and each inspection we conduct is different, therefore our work-scopes and reports are carefully tailored to meet the requirements of each job.

Compiled using easy to understand terminology, report binders are sectionalised via custom made “quick reference” dividers and soft copies are electronically bookmarked, effortless.



A dramatic increase in the oil industry’s awareness of dropped objects and potential dropped object scenarios surge in requirement for inspections. has prompted a these specialised inspections.

Selecting OES’s dropped objects package (DropsTrack) takes the headache out of initiating a dropped objects program, by providing an off-the-shelf solution.

OES provide qualified inspectors to conduct a thorough dropped objects survey of the Derrick/Mast and agreed surrounding areas, documenting findings with photographic support and providing recommendations for their rectification. All findings are then presented in our exclusive corrective actions register format in hard, soft and interactive online copies.

The team also prepare a complete dropped objects scheduled-inspection follow-up program, for post OES inspections by the rig crew. This program is built on a level-by-level basis, detailing items to be checked and what to look for, text is clear and easy to follow, with all items supported by a photographic reference.

OES also have a broad range of experience reviewing, implementing and following up on client’s pre-purchased or internal dropped objects packages should another format be agreed for dropped objects. This ranges from implementing a clients own; or already purchased, dropped objects package to auditing an already implemented dropped objects program.



The statement that Derricks and Masts form the backbone of the drill floor needs no further explanation. OES offers its clients a wealth of expertise and experienced teams to assist in keeping this structure compliant, safe and reliable. OES provides numerous

specialist Derrick and Mast related including:

  • services,
  • Upgrades
  • Repairs
  • API inspections
  • Bolt change-outs
  • NDT
  • Dropped objects surveys
  • Audits
  • Inventories
  • Rope access services and more


OES Liquid Penetrant Inspection

Liquid Penetrant Inspection (LPI) is one of the most widely used non-destructive testing (NTD) methods. Its popularity can be attributed to two main factors: its relative ease of use and its flexibility. LPI can be used to inspect almost any material provided that its surface is not extremely rough or porous.

LPI offers flexibility in performing inspections because it can be applied in a large variety of applications ranging from automotive spark plugs to critical oil and gas components. Penetrant can be applied with a spray can or a cotton swab to inspect for discontinuities known to occur in a specific area or it can be applied by dipping or spraying to quickly inspect large areas. In the image on the right, visible dye penetrant has been locally applied to a highly loaded connecting point to check for fatigue cracking.


OES Magnetic Particle Inspection

Magnetic Particle Inspection (MT) is a non-intrusive method used for detecting defects using magnetic fields and small magnetic particles (i.e. iron filings) to detect flaws in components.

MT is fast and relatively easy to apply, and part surface preparation is not as critical as it is for some other NDT methods. The only requirement from an inspection standpoint is that the component being inspected must be made of a ferromagnetic material such as iron, nickel, cobalt, or some of their alloys.

Ferromagnetic materials are materials that can be magnetized to a level that will allow the inspection to be effective. These characteristics make MT one of the most widely utilized non-destructive testing methods.


OES Acoustic Emission (noise Level) Surveys

Acoustic Emission Surveys are carried out by OES personnel utilizing fully calibrated noise monitoring devices and bespoke software.
Surveys are conducted at the request of the client on both on and offshore facilities, to establish and record background noise levels and qualify noise levels win accordance with the industry standard.


OES RFID (Radio Frequency Identification)

All of the OES services can now be enhanced though RFID tagging, RFID (or Radio Frequency Identification) provides a method of attaching tag to an asset to aid rapid information retrieval. A scan of a tag would pull up information about that asset, including manufacturer information, inspection certificates, maintenance information and so on. An RFID tag can be thought of like a barcode, except is much more rugged, cannot be copied or tampered. It also does not necessarily require line of sight to get a read. This is especially useful for warehousing stock control and management.

Through our partner Askaris, we can also provide innovative database solutions which are especially suited to use in the Oil & Gas Sector. Featuring true scalable architecture, it is able to manage many millions of assets without performance degradation. it also works in environments where there is poor or no internet connectivity.

Applications using RFID technology include:
ARCUS-EX EX Survey with RFID tagging
ARCUS-HORM Hose Register Management
ARCUS- PIPE Drill pipe management
ARCUS-TRACK Asset and maintenance management
ARCUS-DOPP Proactive Dropped Object Prevention Programme.


OES Rope Access

With our own team of IRATA qualified rope access personnel, OES have the capability to expand any of a broad range of inspections to most vertical areas inaccessible by standard methods, therefore removing the requirement for alternative, generally costly and disruptive forms of access, like scaffolding.

This provides our clients with the opportunity to implement any of our broad ranges inspection services in awkward locations as well as the option for a number of specialized derrick services, structural surveys or just providing a team to complete a job in an awkward area.


OES Ultrasonic Flaw Detection & Thickness Gauging

These two main ultrasonic methods use high frequencies sound energy to indicate material defects such as longitudinal and transverse cracks (flaw detection) and dimensional charges such as thickness (thickness gauging).

Typically the UT inspection system consists of a transducer, pulser/receiver, and display unit. A pulser/receiver is an electronic device that can produce high voltage electrical pulses to the transducer. When driven by the pulser, the transducer generates high frequencies ultrasonic sound energy into the material in the form of sound waves. When there are discontinuities. such as inclusions, porosity, cracks, etc. in the sound path, part of the mechanical energy will be reflected from the discontinuities ‘(reflectors;) surface.


OES Vibration Analysis

The OES Oilfield Services Group is excited to introduce a new business offering: the Dropped objects Prevention Programame (DOPP). DOPP is set to raise the standard of Dropped object surveys and which the help of technology, minimize the likelihood of potential drops incidents.

Dropped object area a real hazard within the oil and gas industry and DOPP has been specifically designed with this in mind. DOPP supports and enhances the delivery of a dropped objects prevention plan.
DOPP is the first of a series of new products from OES designed to make managing risk and safety on oil installations easier. By providing control and visibility to rig personal and management so that they are aware of the status of their installation at all times.

A tablet application is introduced at Stage 3. This has been designed to build an inventory of permanent and temporary equipment on the rig and is ultimately handed over to the crow the real-time reference. Information from the surveys is also automatically linked to OES Dropstrack Premium Reporting System. OES also offer a technical query application that allows Drops related queries to be answered and advice received at the push of a button.


Dropped Objects eLearning Awareness Training Package For employees and sub-contractors

Dropped Objects eLearning is an annual, online training and competency verification system that ensures all rig operatives have an up to date knowledge of Dropped Objects best working practices.

Several versions of this course are available, from a version designed for non-technical staff, through to a course for engineers who will actively install and maintain equipment at height.

If all personnel have an up to date, verifiable knowledge of the best DROPS working practices, potential hazards are more likely to be identified and resolved before sn incident occurs.
