RFT for the Provision of Electrical Services Framework at MEDITE Europe DAC ‘25

Description

Medite Europe DAC are seeking tender submissions from suitably qualified electrical companies with extensive experience in the MDF / wood processing industry for appointment to a Framework Agreement for a range of small to medium sized Mechanical works at their plant in Redmondstown, Clonmel, Co. Tipperary, E91 V584. Types of works: 1) Annual Large-scale shutdown works 2) Fortnightly shutdown works 3) Hourly rate works related to projects An example of the type of work involved is listed but not limited to the table below No. Electrical Activity Performance Characteristics 1. Visual Inspections Inspection should look for: Evidence of damage caused by dirt, loose parts, or foreign objects. Verification that air inlets are not blocked. Evidence of moisture and/or dirt build-up Unusual noises, leaking oil seals, or high vibration. Oil level gages (if present) should be checked. Evidence of degradation of foundation, bed plates, anchor bolts Evidence of oil rings turning (if applicable) Evidence of leaking oil and water piping and connections 2. Temperature monitoring of bearings and windings If motor is not equipped with installed sensors: record bearing temperatures and stator temperature using thermo graphic imaging. This data should be trended. The monitoring should be completed at similar motor loading and ambient temperature to allow for accurate trending. 3. Vibration Record and trend vibration levels. This should be done by a trained and experienced technician, preferably a qualified level II technician. 4. Oil Analysis Sample and analyse. Look at overall conditions and check for foreign matter, additive depletion, varnish precursors and metallic elements. 5. Running Current Record and trend all three phase currents and verify the currents are balanced and do not exceed nameplate rating. Each phase should be within +/- 5per cent of the average of all three phases 6. Cabling / Re-wiring Pulling cabling in to place and wiring according to specification outlined. 7. Insulation resistance (IR) Perform IR check between motor leads and ground. This determines condition of the ground insulation. Record, temperature correct and trend Motor Test Acceptable voltage voltage(Vdc) reading 8. Winding Resistance A comparison of the line-to-line resistances of the motor’s winding. This test should be done at the motor terminals using a meter capable of measuring low resistance (milliohms). A typical ohm meter does not have adequate accuracy. Record, temperate correct and trend. Each phase should be within +/- (3 - 5 per cent) of the average of all three phases 9. Bearing Insulation Resistance Check (if applicable) Completed similar to other IR (megger) test. Used to verify condition of insulation on a bearing. Test voltage: 500 Vdc Acceptance criteria: 1 megohm 10. Shaft Total Indicated Run Out (TIR) Measure the trueness of the shaft extension. A high value can cause vibration issues. Acceptance criteria: 3600 rpm max .001 in Please see attached tender doc for full scope of works
