Lets say you operate a ship…
Wärtsilä keeps the worlds ships moving and lights on in cities across the globe. Behind that complex operation is Maximo, supplied by Nexer
Wärtsilä keeps fleets moving and power plants running worldwide. This reference story shows how their teams use IBM Maximo to plan maintenance, forecast parts and resources, and cut unplanned downtime—at scale. It’s a straight look at real operations, not a product demo.
You’ll see how work orders, spare parts, schedules, and reporting are aligned in one system to make maintenance predictable and repeatable across sites. You’ll also see the role Nexer plays: turning business goals into a practical Maximo setup, shaping workflows and data so the system fits the work—and keeps improving.
From Forecast to Work Order—At Scale
The Wärtsilä reference story shows how one system—IBM Maximo—aligns forecasts, work orders, parts, schedules, and reporting across fleets and plants, and how Nexer designs, configures, and supports it to cut unplanned downtime, extend service intervals, and give leaders end-to-end operational visibility.
Maximo fits your operation—at any scale, in any industry
Maximo adapts to you—not the other way around. Its flexible setup lets us mirror your assets, sites, and everyday processes: multi-site structures, job plans and preventive maintenance, service levels and contracts, plus rules that trigger work from real conditions or events. It runs either on your own servers or as MAS in the cloud. With Nexer, the build matches how your crews work today and scales cleanly from one plant to a global fleet—no rip-and-replace
WHY THIS MATTERS
Because downtime costs money and guesswork doesn’t scale. This reference shows how Wärtsilä runs maintenance planning in the real world and what that means for you.
● How forecasts become work, parts, and schedules in one system
● How forecasts become work, parts, and schedules in one system
● What changes when planning is standardized across sites/fleets
● Practical outcomes: fewer surprises, longer service intervals, better visibility
● The split of roles: Wärtsilä operates; Nexer designs, configures, and supports
● The path forward: moving toward MAS without ripping and replacing
RESULTS IN PRACTICE
– Fewer unplanned stops; more work is planned.
– Longer service intervals with a clear PM library.
– Higher wrench time—less chasing parts, more doing the job.
– One way of working across sites; standard job plans and roles.
– Parts and people ready when the schedule says “go”.
– Clear ownership and KPIs; reporting that stands up to audits.
– Faster onboarding—new crews follow the same playbook.
– Scales from one plant to a global fleet without rework.
