ROMVECs maintenance services philosophy

There are two main ways of arranging such on-site service and maintenance.One is with the original equipment manufacturer (OEM) or supplier, and thesecond is with a specialist third party organization. ROMVEC INDUSTRIE is such athird party Service Company. It delivers maintenance services and efficiencyprogrammes in a users facility and accepts some technical and financial risk.Payment is based on meeting quality performance standards and/or energy

efficiency improvements. ROMVEC INDUSTRIE will alsodeliver plant repair and maintenance over the contractperiod.Maintenance warrantycontracts require that amonthly fee be paid by theplant owner; that is, in effect,a continuous full protectionplan for equipment and

accessories. The purpose is to achieve immediate, fast(typically eight-hour) response times by service

personnel in repairing failed equipment from the plant.

S&M and O&M

63 /

8/9/2019 FINAL 54 -72

12/22

Service and maintenance (S&M) agreements are designed to obtain reliablelong-term availability and performance from plant equipment using a competentauthorized third party when the OEM is far enough (generally for the importedequipments) and has not established an own service / maintenance centre inRomania. Operation and maintenance (O&M) agreements, on the other hand,may include the day-to-day operation of the entire plant. This leaves the plant to

ROMVECs on-site technical team to do what they do best.S&M covers boilers equipment (generally burners & automation system) ratherthan the whole boiler house . Most on-site boiler house owners contract outS&M simply because they have to - most dont have the sheer expertisenecessary to carry out routine maintenance tasks on steam boilers, heatexchangers, power generating units, etc., let alone major repair or replacementoperations. From all the thero energetical equipments Gas turbines aredefinitely the province of the professional. In such cases, hosts often contract tobuy maintenance services from the OEM or specialist third party contractor forseveral years at least. Therefore it is usually for the customer (owner) only aquestion of whether to stay with the OEM or to use a third party.Maintenance operations, performed systematically, greatly improve plantreliability, reduce equipment degradation and maximize energy efficiency andshareholder value.

The serviceThe service itself typically offers a full after-installation service that providesmonitoring and maintenance on all systems supplied - tailored to eachcustomers precise needs. ROMVECs Service Department may offer remote 24-hour monitoring operating the installed equipment. Often, automatic phonedialers will contact service personnel for immediate service even before the

owner is aware of a problem. Monthly reports show the electrical and heat loadsand how they are performing. The customer can, therefore, concentrate on coreactivities.

Inclusive five-year (sometimes up to 20-year) service/maintenance contractsprovide full service for scheduled and un-scheduled outages. The requiredengineering and spare parts are usually included, as may be guarantees forplant availability and performance. Penalty schemes mean that the maintenancecontractor pays the bill if it fails to respond to an emergency within the agreed-on time period.Such contracts are generally tailored to larger plants, but for smaller packaged

plant, ROMVEC often suggest that customers opt for a largely fit and forgetunit in the boiler house. This is monitored remotely by the ROMVECs ownengineers back at HQ.

ROMVECs maintenance services offered to the customer

Once a maintenance contract has been settled, it is essential to establishclear lines of communication, feedback and protocols regarding emergencyservice, after-hours service and regular planned maintenance visits. For shortnotice unplanned maintenance, a maintenance staff rota system and 24-hourhelpline guarantee site attendance to customers within a few hours of a call.

64 /

8/9/2019 FINAL 54 -72

13/22

Maintenance scheduling can be problematic, so careful planning is crucial. Thecontract should also clearly state grounds for cancellation.A maintenance service plan should require that the contractor carry out workbased on the plant owners needs and the plant design documentation. It shouldcontain an equipment list and the operating and maintenance tasks for allequipment, along with the service schedule. A list of important data to be

tracked over time should be drawn up - performance, fuel consumption ( a clearparameter for thermal efficiency), exhaust emissions, all temperatures andpressures, electrical and thermal parameters, and other performances.ROMVEC as a maintenance contractor should ensure that periodic instrumentcalibration checks are carried out by independent test establishments orgovernment agencies. For the all-important diagnostics, ROMVECs maintenanceteams use performant calibrated instruments in measuring the variousparameters that indicate correct plant operation.

Remote monitoring

Boiler houses and CHP plants, with their many systems, need careful conditionmonitoring to get the best out of them. Predictive and periodic maintenancetechniques are essential to obtain best service and life. An excellent way ofachieving this is to use remote monitoring techniques. These are highly cost-effective for organizations wanting to re-deploy resources and interrogateunmanned facilities by downloading data to a central site.Also, power plant is increasingly sited remotely and is, therefore, helping tobring the concept of remote monitoring into its own. It is not cost-effective tohave engineers stay for hours in-plant to observe operating strategies. Today,equipment can be checked from the comfort of a cosy office, sometimeshundreds of kilometres away.

Remote monitoring systems typically employ: simple hard-wired fieldbus systems forplant-wide applications wireless systems such as radio frequencyor GSM telemetry for communication that ismore remote the internet for global communication.Such remote monitoring covers many layers,including supervisory control and dataacquisition (SCADA), condition, environmental

and equipment monitoring, communication/networking, industrial control and automation,telemetry and device equipment management.The data obtained can be interfaced to othersystems. Very sophisticated software-oriented,non-intrusive, on-line signal processing and analysis techniques are available sothat plant operation can continue even while investigation is taking place. Theserely on state-of-the-art signal processing and analytical techniques, and theyalleviate the need for costly purpose-built monitoring systems.

Electrical equipment maintenance

ROMVECs maintenance teams are aware they must carry out all maintenancework necessary to ensure that a boiler / equipment runs correctly over a longperiod, whatever its manufacturer and rating. Preventative maintenance is just

65 /

as important here. Electrical inspections include all auxiliaries such as the powerdistribution unit, any batteries and chargers.
