Maintenance Services

Maintenance Services

From single equipment maintenance to comprehensive maintenance packages, our maintenance offering supports the full lifecycle of our products.



The first phase is to identify the status of the equipment. This results in fact-based decision support material, covering both the equipment status and an evaluation of performance enhancing upgrade opportunities. The assessment and planning phase results in a clear Scope of Work (SOW) with identification of critical materials and source. Experienced project managers provide decision support which helps to ensure realistic time assessments.
In the execution phase, materials are prepared and used for either overhaul and repairs or directly for installation and commissioning.


Inspection Services

Our rig inspection program is proactive and equipment specific. With the use of annual and preclass inspections as well as condition monitoring tools we are able to detect faults early. All inspections are carefully prepared by reviewing and analyzing the maintenance and usage history. After the equipment inspection, test results and potential degradation issues are identified and reported to you. Our technical support professionals provide you with detailed advice on the appropriate Scope of Work (SOW) for maintenance to increase your rig’s uptime. With improved maintenance planning, potential HSSE and commercial risks of maintenance are minimized.


Our inspection services enable specific, condition based planning of maintenance

Rig Storage and Reactivation

Many of our customers experience challenges when reactivating a stacked rig due to degraded equipment and unknown condition of the equipment. As an Original Equipment Manufacturer (OEM), MHWirth provides reliable, safe and efficient rig storage and reactivation services to ensure efficient and predictable reactivation process. This will qualify your equipment for an extension of Certificate of Compliance (COC). Depending on our customers’ operational needs, MHWirth can provide a full package of reactivation services. Our Service Account Managers will support and guide you during the reactivation process.


OEM documented condition of equipment will benefit you for new drilling contracts, and save you cost when bringing your rig back to operation

Condition Based Maintenance and Condition Monitoring

As a certified service supplier, we advise on maintenance requirements based on the actual condition of the equipment instead of on a calendar based schedule. This provides you with scheduling flexibility and a lower total cost of ownership on your  equipment. In addition to manual inspections by our experienced specialists, our Riglogger™ technology continuously collects data about the condition and use of the equipment. Combined with other condition monitoring technologies on the rig and detailed analysis, this gives an accurate status report of the equipment.
Maintenance can be scheduled to suit your operation allowing actions to be taken before critical faults occur. This results in the extended life of the equipment and reduces the total cost of ownership.


As a certified supplier of condition monitoring services, we support condition based maintenance
