With our portfolio of Condition Monitoring (CM) tools, MHWirth assists you in optimizing maintenance costs and improving the operational predictability of your rig.Condition Monitoring (CM) improves the knowledge about actual equipment condition and upcoming maintenance needs. Equipment availability and predictability in operations are our main focus areas.

With our comprehensive portfolio, MHWirth can execute any CM services. Our portfolio comprises the following tools and techniques:■ Visual inspections – suitable for all equipment subject to

maintenance and classification■ Vibration monitoring – suitable for rotating drilling

equipment. The level of CM instrumentation required varies depending on machine criticality, ease of access and mechanical design

■ Oil monitoring – suitable for equipment with lube oil or hydraulic circuits. The level of instrumentation varies depending on machine criticality and physical layout

■ Structural resume – documentation of load carrying integrity is relevant for all class I lifting equipment when pursuing changes to the five-year reclassification interval

MHWirth is an approved CM service supplier by DNV for contribution towards customers applying for offshore CM survey arrangements according to DNV and ABS regulations.

Track Record in Vibration MonitoringMHWirth has successfully applied vibration monitoring on top drives for more than ten years – from manufacturing throughout the value chain and into operation. The technique has also been adopted in the company’s internal Quality Assurance (QA) work to ensure optimal condition of all new and overhauled top drives.

Condition Monitoring

Benefits

■ Detailed information about machinery condition, also with regards to non-visible components

■ Allows early fault detection, leading to improved predictability in operation and reduced risk of costly equipment failures and downtime

■ Reduced maintenance costs when replacing calendar based maintenance with Condition Based Maintenance (CBM)

■ Vibration monitoring as CM technique is critical when pursuing offshore CM survey arrangements
