Asset renewal
Upgrade or replace: which option meets the need, and at what cost over time?

Compare your options. Invest with a clear rationale.
Maintain, upgrade or replace: we compare future spending and the feasibility of each option. Your teams receive a costed dossier to choose a solution, prepare the budget and decide when to act.
Is a cost or cause still unclear? A focused diagnostic can complement the study.
A defined need
The required service and site constraints.
Options compared
Future spending, production and feasibility.
A documented decision
A recommendation, a budget and a schedule.
Your existing installations
An investment grounded in your operations.
Replacing a machine involves more than its purchase price. Installation changes, energy, maintenance and interrupted production affect the cost and value of the project.
We start with the required service and how the site actually operates. Finance, maintenance and production agree on common assumptions to compare feasible options.
Where we start
- Supplier quotes
- Operating expenses
- Maintenance history
- Consumption and volumes
- Drawings and manufacturer data
- Production constraints
- Financial assumptions
The questions we handle
The choices behind your next investment.
Our studies bring together the economic and technical aspects of the decision: what each option costs, what it delivers and what must be checked before committing.
Recurring repairs
Should you keep repairing or invest in a modification that addresses the cause?

An investment decision
P-204: keep repairing or invest?
Repairs to P-204 keep recurring. Replace the pump, modify the installation or adjust its operation: compare the future spending and consequences of each option.

Costs are reconciled with available sources. Technical checks target uncertainties that could change the decision.
What could change the choice
A new pump will not necessarily address the cause of the repairs. These checks help determine which options are relevant.
Cavitation
Available NPSH against required NPSH at the actual operating point, high-frequency noise and vibration, impeller condition at inspection.
Incorrect sizing
Measured operating point against the OEM curve, current process needs against design data.
Operation away from BEP
Flow distribution over the history, time spent far from the best efficiency point.
Misalignment
Vibration components at one and two times running speed, alignment reports after interventions.
Control strategy
Control valve behaviour, start-stop cycles, setpoint changes.
Inadequate piping
Straight run at suction, elbows close to the flange, loads transmitted by the piping.
Lubrication
Lubricant type, top-up frequency, bearing temperature, oil analysis.
Process constraints
Fluid temperature, viscosity and solids content against selection assumptions.
What you receive
A dossier to choose and commit.
You receive the economic and technical inputs to review the project, prepare its budget and organise the next steps with your teams.
A need and its assumptions
Required service, site constraints and sources used. Documented spending and estimates remain identifiable.
Options compared
Future spending, availability and feasibility over the same period. The effects of key assumptions on the choice are examined.
A costed recommendation
The preferred option, planned budget and reasons for the choice. Spending commitments are distinguished from expected benefits.
A schedule to prepare
Deadlines, shutdown constraints, specialist calculations and approvals needed to prepare implementation.
The study prepares the decision. Works, specialist studies and financing support are scoped separately for each project.
Tools and partners
The right expertise to support the choice.
Your software stays in place
Your ERP, CMMS and calculation tools provide spending, histories and simulation results. We bring them together in one dossier to compare options.

FAQ
What to clarify before an engineering study.
What investment are you preparing?
A replacement, an upgrade or several options to compare: let’s define the decision, scope and data needed for the study.
Discuss my projectAgreed scope · Quoted study
Renewal, upgrades, capacity, availability or energy: we study options for an asset, a line or an agreed scope. Production needs and site constraints guide the comparison.
Quotes, operating expenses, consumption, volumes and maintenance history, supplemented by drawings and manufacturer data. Financial assumptions and the required service are defined with your teams.
No. We compare continued operation, upgrades, replacement and relevant operating changes. A solution must meet the need and its constraints; purchase price alone is not enough to choose it.
Over the same period and for a comparable level of service: purchase, installation, operation, energy, maintenance, downtime and residual value as relevant. Price and discounting conventions are agreed with finance. We examine assumptions that could change the choice while avoiding double counting.
NetForge prepares the inputs and incorporates results into the analysis. Calculations run in the appropriate tools. When a regulatory sign-off, specialist expertise or on-site work is required, an engineering firm, EPC, manufacturer or authorised expert performs or validates the work.
Diagnostics explain a cost or uncertainty. An investment study examines options to prepare the choice and budget. REX supports ongoing decision tracking. Financing addresses the means to deliver the selected project. The study is a separate engagement from the REX subscription.
