Case Study: 12-Month PdM Rollout at a Mine and CHP — Artesis, Bently and SDT

Note: composite case based on typical KEG TRK projects in Kazakhstan/CIS. Figures are anonymised; methodology reflects real deployments.

Site: concentrator + CHP (~450 drives, 2 × 60 MW steam turbines, 4 DGS, 12 conveyor lines).

Strategy: three-tier model + Artesis + Bently + SDT integration.

12-month timeline (summary)

Quarter	Focus	Key tools
Q1	Discovery, SDT baseline	SDT 340, LUBExpert
Q2	Fleet scan, conveyors	AMT Pro, Orbit DCM
Q3	Online pilot	e-MCM, e-PCM on DGS
Q4	Scale + IoT	+8 e-MCM, Artesis IoT

Results at month 12

Metric	Before	After
Unplanned drive trips / year	23	9
Conveyor downtime (hours)	186	62
Compressed-air leaks	—	−34%
Online ESA points	0	13
Programme ROI	—	14 months

Technology contribution

• SDT — fast ROI on leaks and early bearings
• AMT Pro — prioritised e-MCM targets
• Orbit DCM — conveyor trips prevented
• e-MCM — mill and pump lead times 3–6 weeks
• e-PCM — DGS test-run trending
• Bently 3500 — turbines unchanged, complemented by e-PCM on generator
• Artesis IoT — holding-level reporting

Lessons

Start with AMT Pro + SDT, not 20 e-MCM points. One programme owner. Weekly cross-tool review. IoT in Q4 when data exists.
