I assisted with various electrical and mechanical maintenance tasks aboard an offshore vessel including replacing submersible pumps and electrodes, verifying shale shaker engines, checking mud pump engines, greasing pumps and agitators, cleaning air conditioning systems, checking refrigerant pressures, replacing lamps, assisting with a pressure washer connection, replacing a winch brake gearbox and encoder, measuring voltages of fuses and contactors, and checking engine and connection temperatures with a thermal camera.

1. 1. I receivedinformationaboutelectrical intallation, the locationandprinciple of operationforeachpart
of it:generators,transformers,electrical panel etc;
2. . I participatedinsubmersible pumpreplacement, i measuredandcheckedinsulationresistances
(withmegohmetre) atbothpumps,the replacedandthe new;
3. I participatedinreplacementelectrodesat "Anti-FoulingSystem": beforereplacement andafter
beingassembledandtestedinstallation, Imeasured insulationresistance of the 4 new electrodes;
4. I participatedinverificationof shale shakers engines( twomotorsfor linearmotion,one motorfor
eliptical motion); usingthe ammeteri measured currentintensityforeachphase andinsulation
resistance;
5. I participatedincheckingthe enginesof mudpumpNo.1 ( DC motors);On thisoccasionI checkedthe
condition of eachsetof brushes, connectionscondition,i cleanedthe collector,andalsoImeasured
insulationresistance;
6. I greasedthe the mud pumpsand mudagitators engines;
7. I participatedinthe cleaningof airconditioningsystems:cleanfilters,removableindoorunitand
cleanthe turbine;
8. I checkedthe pressure of the refrigerantinairconditioningsystems,andwhere wasnecessaryi
completed;
9. I replacedlamps(neon) burnedfromdifferentlocations(legs,accommodation,deck etc.);
10. I participatedinapump supplypressure washer: afteri checkedthe operatingparameters Ichosed
the correct cable whichI connectedto440 V panel (panel connectedtothe auxiliarygenerator60 HZ );
11.I participatedinreplacementof gearbox andencoderfromwinchbrake ( LIDAN brake) ;
12. I measuredthe voltage (withmultimeter) tofusesandcontactorsof differentpanels (Derrickpanel,
sumersiblepumpspanel etc);
13.I checkedwiththermovisioncamerathe enginesandconnectionstemperature;
