NNT Services
Optimize and Empower: At NNT we unlock the full potential of your industrial equipment with our comprehensive suite of services. From gas turbines and turbomachinery to pumps and gearboxes, we offer expert solutions across all major brands (GE, Baker Hughes, Siemens, etc.) to maximize your equipment's performance, reliability, and lifespan.
01Gas Turbine Mapping
We assess how a gas turbine behaves across its operating range by relating load, ambient conditions, process constraints and available control-system data. The work can include reviewing fuel and air scheduling, combustion-related trends and the settings that influence stable operation, with the applicable equipment documentation as the reference.
Our approach combines operating-data review, an agreed measurement plan and a documented comparison of operating points. Proposed adjustments are evaluated against OEM limits, protection requirements and site procedures, helping the client identify practical tuning opportunities and the checks needed before implementation.
Service scope
- Operating-point and trend assessment
- Mapping and tuning test planning
- Documented findings and recommendations
02Vibration Analysis
We help maintenance teams understand vibration behaviour in turbines, compressors, pumps, motors and associated equipment. Where suitable measurements are available, we review overall levels, frequency spectra, phase relationships and operating conditions to distinguish recurring patterns from transient events.
The investigation considers possible contributors such as imbalance, alignment, looseness, process excitation and bearing-related behaviour. We connect the measured evidence with machine configuration and maintenance history, then propose targeted checks and corrective actions. This gives the maintenance team a clearer basis for prioritising work rather than relying on an isolated alarm value.
Service scope
- Measurement and sensor suitability review
- Spectral and operating-condition analysis
- Maintenance priorities and follow-up checks
03Electrical Analysis & Commissioning
We support the transition from installed electrical equipment to a documented, operable system. The scope is defined around the equipment and interfaces involved and can include drawing review, inspection support, signal verification, interlock checks and coordination of the relevant electrical tests.
Particular attention is given to the interfaces between electrical equipment, control systems, protection functions and operator displays. We help structure test procedures, record discrepancies and track corrective actions through commissioning. Work is coordinated with site isolation procedures, the responsible electrical personnel and the applicable supplier requirements.
Service scope
- Electrical and control-interface review
- Commissioning procedures and test records
- Punch-list tracking and handover support
04Performance Tests
We plan and support performance assessments that compare actual equipment behaviour with agreed operating requirements. Depending on the asset, the scope can cover generator output, efficiency, temperature rise, auxiliary consumption and the relevant turbine or process parameters.
Useful conclusions start with representative operating conditions and trustworthy measurements. We review instrumentation, test boundaries, stabilisation criteria and data recording before assessing the results. Reports describe the calculation basis, operating conditions and measurement limitations, allowing the client to separate an equipment-performance issue from changes in ambient conditions, load or data quality.
Service scope
- Test boundaries and measurement planning
- Operating-point recording and calculations
- Performance report and improvement priorities
05Data Collection & Analysis
We turn fragmented operating and test records into information that can support engineering decisions. Data can be assembled from control-system exports, historians, commissioning records and condition-monitoring sources, with consistent tag identification, units and timestamps.
The analysis focuses on the question the client needs to answer: a performance change, a recurring alarm, an equipment event or a comparison between operating periods. We check gaps, sampling behaviour and operating context before drawing conclusions. The resulting trends and summaries explain what the data supports and what requires a further measurement or site check.
Service scope
- Tag, unit and timestamp reconciliation
- Trend and event comparisons
- Traceable engineering summaries
06Generators & Protections
We provide engineering support for generator commissioning, startup and troubleshooting, including the interfaces between the generator, excitation system, protection equipment and plant controls. The work can cover configuration review, signal and interlock verification, event-record interpretation and coordination of agreed functional tests.
Protection settings and test boundaries are assessed against the approved protection study, equipment documentation and the site's operating requirements. We help identify discrepancies, improve the quality of test records and organise handover information. Any proposed setting change follows the client's engineering approval and authorised implementation process.
Service scope
- Generator and protection-interface checks
- Event and disturbance-record review
- Functional-test and handover support
07Remote Support
Remote engineering assistance helps site teams investigate faults, review configuration and prepare corrective actions without waiting for every issue to become an on-site visit. We can examine the supplied trends, event logs, logic extracts and operating history, then work with local personnel to narrow the problem and define the next checks.
Support may be organised for planned troubleshooting sessions or agreed on-call coverage. Access, response times and escalation routes are established for each engagement. Recommendations are documented so the site retains a clear record of the evidence reviewed, the proposed action and the items that still need local verification.
Service scope
- Remote evidence and configuration review
- Structured troubleshooting with site personnel
- Agreed support coverage and escalation
08Advanced Vibration Analysis
For persistent or complex vibration problems, we extend the investigation beyond a single spectrum or overall reading. The scope can include synchronous and non-synchronous components, phase behaviour, run-up and coast-down data, transient events and comparisons across multiple measurement locations.
We correlate these observations with speed, load, temperature, process conditions and maintenance interventions to test competing explanations. Where measurements do not discriminate between possible causes, we define the additional evidence needed. This supports a focused inspection or repair plan and a meaningful check of whether the intervention addressed the observed mechanism.
Service scope
- Transient and multi-channel assessment
- Correlation with operating and maintenance history
- Discriminating measurements and verification planning
09Spare Parts
We support the technical definition and sourcing coordination of spare parts for gas turbines, steam turbines and associated auxiliaries. The starting point is an accurate equipment identity, part reference, revision and installation requirement, helping avoid selection based only on a general description.
The scope can include reviewing bills of materials, identifying critical spares and checking the information needed to evaluate a quotation. Where a replacement or alternative is considered, compatibility, documentation and the required approval are addressed explicitly. Provenance, availability and delivery commitments are confirmed for each supply enquiry rather than assumed.
Service scope
- Part identification and compatibility review
- Critical-spares and outage-material planning
- Supplier documentation and sourcing coordination
10Beyond Services, a Partnership
We work with clients to understand the operational problem behind the requested task, then shape a practical engineering scope around it. This may combine equipment expertise, control-system review, site coordination and data analysis instead of treating each discipline as an isolated activity.
A useful partnership has clear priorities, responsibilities and checkpoints. We agree the deliverables, identify dependencies and maintain a visible record of decisions and open actions. The aim is to leave the client with an implementable solution and usable technical knowledge, supporting continuity after the immediate intervention has ended.
Service scope
- Needs assessment and scope definition
- Coordinated engineering workstreams
- Decision records and knowledge transfer
11Explore Your Potential
We help clients identify where an existing installation could operate more reliably, use its information more effectively or reduce avoidable maintenance effort. An initial review can examine recurring problems, bottlenecks, manual tasks, obsolete components and opportunities to improve the use of existing controls and data.
Opportunities are prioritised by operational value, implementation effort and the evidence available. The outcome is a staged improvement roadmap, distinguishing practical near-term measures from changes that need further study or investment. This gives the client a clear basis for deciding what to investigate, implement or defer.
Service scope
- Operational opportunity and gap review
- Prioritised improvement options
- Staged technical roadmap
12Compressor & Steam Turbine Optimization
We assess compressor and steam-turbine operation in the context of the process they serve. The review can relate performance trends to inlet and outlet conditions, speed, load, control behaviour and auxiliary-system condition, identifying where the operating envelope or equipment health may be limiting useful output.
For compressors, the scope may include reviewing the available performance information and anti-surge interfaces; for steam turbines, it may include steam conditions, valve behaviour and governing-system trends. Recommendations connect the evidence to practical operating, maintenance or control improvements and specify the checks required before changing an approved configuration.
Service scope
- Process and equipment performance review
- Control and auxiliary-system assessment
- Prioritised optimisation and verification actions
13Engineering Assessments & Reverse Engineering
We help rebuild a reliable technical picture when drawings, configuration records or equipment documentation are incomplete. The assessment combines available records with agreed field observations, measurements and system exports to identify interfaces, dependencies and differences between documented and installed conditions.
Reverse-engineering work can support replacement planning, interface design, configuration recovery and maintenance preparation. Deliverables identify the source of each conclusion and distinguish verified information from assumptions that still need checking. The resulting documentation gives future interventions a stronger engineering basis and reduces reliance on undocumented site knowledge.
Service scope
- As-installed information and interface review
- Drawing and configuration reconstruction
- Assumption register and technical recommendations
14Precise Outage Planning & Execution
We support outages from scope definition through execution tracking and return-to-service preparation. Planning can include equipment priorities, work packages, critical spares, specialist resources, inspection points and the dependencies that determine the practical sequence of work.
During execution, we help coordinate technical activities, track findings and manage the actions needed for handover. A clear inspection and test plan connects the maintenance work with the restart checks, rather than leaving acceptance to the final day. This helps teams control avoidable delays and make informed decisions when the outage reveals unexpected conditions.
Service scope
- Work packages, resources and outage dependencies
- Inspection and corrective-action tracking
- Restart readiness and handover records
15Pump & Gearbox Reliability
We support the investigation and maintenance planning of pumps, gearboxes and their associated drivers. The review can connect vibration, temperature and lubrication information with alignment, operating duty, process conditions and the history of repeated interventions.
For pumps, hydraulic operating conditions and possible cavitation or recirculation are considered alongside mechanical behaviour. For gearboxes, the investigation may examine load, lubrication condition and gear-mesh-related measurements where available. Findings are translated into targeted inspections and practical maintenance priorities, followed by a check of performance after the agreed corrective work.
Service scope
- Mechanical and operating-duty assessment
- Lubrication, alignment and condition-data review
- Reliability actions and post-maintenance checks
16Advanced Diagnostics & Optimization
We combine operating trends, control-system behaviour and equipment-condition evidence to investigate problems that cross disciplinary boundaries. A symptom such as unstable load, elevated vibration or reduced output may involve process constraints, instrumentation, control configuration or a mechanical condition; the investigation follows those connections.
Our approach tests explanations against timing, operating changes and the available measurements. Improvements are ranked by likely value, required evidence and implementation effort. Where appropriate, targeted instrumentation or a controlled test is proposed before committing to a larger change, helping the client direct expenditure toward the cause that the evidence actually supports.
Service scope
- Integrated process, control and equipment diagnosis
- Hypothesis testing and targeted measurement plans
- Prioritised optimisation actions
17Gas Turbine Excellence
We support gas-turbine installations across commissioning, startup, operation, troubleshooting and maintenance preparation. The scope brings together the turbine, its auxiliaries, instrumentation, control system and operator interfaces, recognising that reliability depends on the complete installation.
Work can include reviewing recurring operating issues, checking configuration against available documentation and preparing test or maintenance activities. We help clients connect immediate troubleshooting with longer-term reliability priorities, using a documented record of findings and corrective actions. The intended outcome is a clearer path to dependable operation and a more informed use of maintenance resources.
Service scope
- Lifecycle engineering and auxiliary-system review
- Operational troubleshooting and test support
- Reliability and maintenance improvement planning
18Turbomachinery Expertise
We provide engineering support for rotating-equipment applications where mechanical performance, process requirements and control behaviour must be considered together. The scope can cover gas and steam turbines, compressors, pumps and related auxiliaries across commissioning, operation and maintenance.
Our work starts with the specific machine configuration and operating duty, then connects the available measurements, documentation and inspection findings. We can help structure commissioning checks, investigate recurring issues and prepare maintenance priorities. Recommendations identify the equipment and interfaces involved, so the client can assign the right action to the right discipline.
Service scope
- Machine and process-interface assessment
- Commissioning and troubleshooting support
- Condition-based maintenance recommendations
19Site Management Mastery
We support the coordination of technical activities on industrial sites, connecting engineering requirements with the day-to-day execution of work. The scope can include work-front planning, specialist coordination, interface management, technical queries and progress reporting.
Clear responsibilities and current information are essential when several contractors and disciplines share the same installation. We help maintain action lists, inspection records and handover requirements, bringing unresolved technical items into view early. Work is coordinated within the client's permit, isolation and HSE arrangements, with return-to-service readiness considered throughout the activity.
Service scope
- Technical coordination and interface management
- Progress, queries and action tracking
- Inspection records and handover readiness
20Commissioning & Startup Success
We help industrial teams move from installation completion to controlled startup through a defined sequence of checks. Activities may include mechanical-completion review, I/O and loop verification, interlock tests, auxiliary-system checks and coordination of the agreed functional-test programme.
Startup support connects the test procedures with the equipment operating limits, protection functions and operator information. We record discrepancies, track the actions needed for acceptance and help organise the documentation for operations and maintenance. Readiness is demonstrated through completed checks and resolved priorities, rather than assumed from installation progress alone.
Service scope
- Commissioning sequence and procedure preparation
- Functional testing and startup coordination
- Acceptance records and operational handover
21Our Skilled Engineers
We organise engineering support around the expertise the assignment requires, whether the immediate need is rotating-equipment troubleshooting, commissioning, controls, operator displays or data analysis. The objective is to provide practical technical assistance that fits the installation and the client's available resources.
Engineers work from the applicable documentation, supplied evidence and agreed procedures, maintaining a clear record of findings and open actions. The engagement can include collaboration with site teams, support for specialist interfaces and knowledge transfer. Responsibilities, access and deliverables are defined at the start so the support integrates effectively with the client's organisation.
Service scope
- Assignment-specific engineering support
- Collaboration with operations and maintenance teams
- Technical records and knowledge transfer
Automation, Digital Systems & Diagnostics
22Industrial Automation & Control Systems
We support the assessment, troubleshooting and evolution of industrial control systems, including GE Mark VIe / Mark VIeS and ToolboxST environments. The scope can include control-logic review, I/O mapping, configuration comparison, sequence analysis and investigation of inconsistent signal behaviour.
We trace information from field signals through control logic to operator displays and event records, helping distinguish communication, configuration and equipment issues. Proposed modifications are prepared with documented interfaces, verification steps and a recovery plan. Changes to critical control or protection functions are subject to the site's engineering approval and commissioning process.
Service scope
- Control logic, sequences and configuration review
- Field-to-controller-to-HMI signal mapping
- Change planning, test procedures and recovery preparation
23HMI / SCADA Modernization
We modernise operator interfaces with a focus on clarity, continuity and maintainability, including GE CIMPLICITY environments. The scope can cover screen development, point mapping, scripts, alarm presentation and recovery of existing configurations, with the operator's real tasks as the starting point.
A staged approach can improve an installed system without requiring a complete replacement. We review obsolete dependencies, repeated manual work and display inconsistencies, then define the workstation, application and interface changes needed. Migration plans address backups, licensing dependencies, test cases and rollback, helping preserve essential operator functions during the transition.
Service scope
- Operator screens, alarms and point mapping
- Automation scripting and configuration recovery
- Workstation migration and continuity planning
24OPC & Industrial Communications
We help industrial teams connect and troubleshoot data interfaces using OPC DA, OPC UA and EGD. The work can include endpoint and server configuration review, tag mapping, update behaviour, network dependencies and assessment of the compatibility between legacy and newer systems.
For OPC UA, certificate trust and session settings are considered alongside data quality and subscription behaviour. For legacy interfaces, dependencies and migration options are identified explicitly. Verification follows a defined signal path and test matrix, helping the client distinguish a successful connection from reliable transfer of the data that the application actually needs.
Service scope
- Protocol, endpoint and tag-map review
- Certificate, quality and update diagnostics
- Integration testing and migration assessment
25Historian & Operational Data
We design and improve historical-data collection around the engineering questions and operating tasks it must support. The scope can include tag selection, sampling and deadband requirements, trend configuration, alarm and event retention, and the interfaces between the control system, SCADA and historian.
Collection design balances useful detail with storage, network and maintenance requirements. We review timestamp consistency, gaps and signal quality before using the history for reporting or analytics. The result is a clearer data structure for troubleshooting, performance assessment and future condition-monitoring or machine-learning applications, with priorities tied to actual operational use.
Service scope
- Historical tag and collection-strategy design
- Trend, alarm and event-data review
- Data quality, retention and capacity planning
26Trip Investigation & Troubleshooting
We investigate turbine and compressor trips by reconstructing the event sequence from available control logic, trends, alarms, event records and instrumentation information. The review follows the signal and logic paths that could explain the shutdown, comparing their timing with the actual machine and process behaviour.
A documented investigation separates observed events from the supported preliminary mechanism and any physical defect that remains unverified. We identify the measurements or inspections that can distinguish between competing explanations, then help prepare targeted verification steps. This gives the site a practical basis for corrective work and a clearer record for reviewing recurrence.
Service scope
- Event-sequence and control-logic reconstruction
- Quantitative comparison of signals and timing
- Targeted field checks and corrective-action planning
27Electrical Asset & Condition Monitoring
We support monitoring architectures for electrical assets, energy use and equipment condition, connecting suitable measurements with the information maintenance and operations need. The scope can include meters, sensors, gateways, communication interfaces and the integration of measurements into dashboards or historical records.
Where appropriate, the assessment can consider motor current signature analysis alongside load, supply conditions and other condition indicators. We review measurement suitability, baseline requirements and interpretation limits before proposing monitoring actions. A staged design helps clients prioritise important assets and expand the system as the usefulness of the information is demonstrated.
Service scope
- Measurement and monitoring architecture
- Electrical, energy and motor-condition data integration
- Baseline, alarm and maintenance-use assessment
AI, Maintenance & Industrial Productivity
Practical digital services that build on your installed equipment, connect engineering knowledge with operating data, and help maintenance and operations teams make better use of their time.
28AI & Machine Learning for Industrial Productivity
We help clients apply AI and machine learning to defined industrial problems: identifying abnormal behaviour, recognising operating patterns, prioritising investigations and reducing repetitive information work. Applications are selected around a measurable operational need and the data already available from historians, SCADA, maintenance records and engineering documents.
A practical engagement progresses from data assessment and baseline analysis to a bounded pilot, historical validation and controlled integration into existing workflows. Statistical methods and machine learning are compared with simpler rules so the solution remains proportionate to the problem. Performance, false alerts and user feedback are reviewed before wider adoption, with engineering judgement retained for consequential decisions.
Service scope
- Use-case selection and data-readiness assessment
- Anomaly detection, pattern analysis and pilot development
- Model validation and integration with existing workflows
29Preventive & Predictive Maintenance
We help maintenance teams combine scheduled preventive work with condition-based and predictive information. Plans can relate equipment criticality, operating hours, starts, supplier recommendations and maintenance history to condition indicators from vibration, electrical measurements, process trends and inspections.
Machine learning may support the detection of developing anomalies or changes in degradation behaviour where the available data permits meaningful validation. Findings are translated into prioritised inspections, work-order recommendations and maintenance-window planning. Predictions are evaluated against historical events and operational feedback; remaining-life estimates are considered only where asset history and failure evidence support them.
Service scope
- Asset criticality and preventive-task review
- Condition indicators and predictive-model assessment
- Maintenance priorities, inspection triggers and planning support
30Cost-Conscious Modernization & Asset Life Extension
We look for ways to improve an existing installation through targeted engineering changes before committing to a complete replacement. Opportunities can include repairing data interfaces, simplifying scripts, improving operator screens, upgrading selected workstations and adding measurement or analytics around equipment that still serves its purpose.
Options are compared by compatibility, operational benefit, implementation effort and lifecycle cost. A phased roadmap distinguishes configuration improvements from software, hardware or instrumentation investment, making budget decisions easier to justify. The objective is to keep expenditure proportionate and reduce avoidable replacement work while addressing the actual reliability or usability constraint.
Service scope
- Existing-system and obsolescence assessment
- Reuse opportunities and incremental upgrade options
- Phased implementation and cost-benefit comparison
31Operator Workflow Simplification & Decision Support
We redesign routine operator tasks around the information people need to act confidently. The scope can include clearer synoptics, consistent navigation, practical alarm context, guided checks, automated reporting and better access to approved operating or maintenance procedures.
Where useful, an AI-assisted knowledge interface can help retrieve the relevant procedure, summarise an event record or assemble a draft shift report from approved sources. Responses should retain source references and expose missing information rather than conceal it. Integrations support the operator's decisions; critical actions and control changes remain within the site's authorised procedures and review process.
Service scope
- Operator-task mapping and HMI usability improvements
- Guided workflows and routine-report automation
- Source-backed engineering knowledge and decision support
32Industrial Data Readiness & AI Integration
Reliable analytics starts with a reliable connection between the asset, its signals and its operating history. We assess whether existing data sources provide the timestamps, units, sampling behaviour, maintenance context and event labels needed for the intended monitoring or AI application.
The work can include selecting a useful tag set, reconciling naming conventions, checking gaps and defining interfaces between historians, SCADA, maintenance systems and an analytics environment. A staged integration keeps data access and processing proportionate to the use case. Clear ownership, access controls and validation criteria help the client maintain the solution as equipment, configurations and operating conditions change.
Service scope
- Signal inventories, context and data-quality checks
- Historian, SCADA and maintenance-data integration planning
- Access, validation and ongoing model-monitoring requirements
