Craig T Mitchell Online<3000KW Chiefs Oral 18Th June 2020 GMA Candidate
Carried out By Andrew Duewer @ 1000-1125

ON the road up to the oral I was emailed by MCA Office(mine was Glasgow) confirming I had access to Microsoft Teams and requested scanned copies of Government ID(Passport, Driving licence) Discharge book and NOE and confirmation that you had a office area where you could take the exam. Once confirmed you have the above a time is allocated and a link is sent for participation.

My Duewer started off by explaining the situation and confirming the secutity of the system, he was happy I had down loaded the teams App and as I was using a MACBOOK seemed happy, I’m thinking if it was a PC you’d need to ensure virus softwear etc. He then confirmed my identity by me showing him my passport and discharge book. He then wanted the laptop camera panned around the room to ensure I was alone.

He then started the exam,
Question seemed to flow into each other so there was no specific numbers. He started off with Engine performance, as chief engineer on a UMMS ship you notice after a period of UMMS black smoke exiting the funnel whats your actions?
I state that I would first ask the bridge to reduce speed and after donning correct PPE I would proceed to the control room to access engine parameters. I’d be checking all exhaust temperatures and if there was a deviation on one would request an engine shut down as suspected a faulty injector, he seemed happy with this.

He then carried on stating all exhaust temperatures were low and how would you proceed? I stated this now sounds like a lack of air problem so I would investigate the charge air system, blocked coolers, turbo, block air filters, blocked engine room ventilation, I stated if the door to the engine room was stiff to open I would investigate external flaps and if they were clear request an engine shut down as had indication of blocked air supply to the engine room. He was reluctant to realy on any sensors and wanted to hear local temp pressure gauges and manometers to gauge coolers.

We then moved onto assessing engine performance, he was not happy with the use of any Dr Diesel system and wanted to hear about taking manual settings like,Govenor Quadrant , fuel rack positions, turbo before and after temps(using “Loss of Q” for load on turbo), cooler before and after temps, all manually taken and then peak pressures to asses engine load. Wanted to hear about comparing to previous readings, he stated that the engine performance data from test bed was not really relevant as it’s an old engine now.

We them moved on to Marpol Aneex 6 and what information we’d find from this relating to cert held on board, I stumbled here a great deal but he pulled me through. Wanted to hear about what information you’d get on the IAPP cert etc.

We moved from there to Electrical discrimation, I was all over this by couldn’t remember the wee relays were called and he want to here how an over current trip in a breaker work, I talked about bymetalic strips and a coil which the current is passed through to generate the heat to trip the breaker.

We them moved onto a new component to be fitted with a sensor cable to be ran through the engine room how would you do it.
I stated that the bulkhead penitiration must by A60 rated and the cable should be sufficiently shielded and kept away from and electrical power cables to prevent disrupitons. Talked about meatal cable securing on the deck head for fire and also if you had to run over a power cable how would you do it, I said at 90 dgress and as quickly as possible with additional shielding if possible. He seemed happy with this.

Moved onto A60 bulkheads, he was not happy with the no higher than 139 degree above ambient temp in 60 mins at all. What he wanted was “prevent the passage of smoke, flame or heat for 60 mins” for an A0 we talked a great deal about this and he seemed happy with my answer of the smoke/flame/heat thing.

We than moved onto fire fighting and particularly BA controller, I said the BA controller should only have one job and a stop watch/alarm on his board to give him the times the team should be out etc. He was very keen on the alarm bit and that the tea should be well out into the fresh air before the whistle goes off.
Afte all of this he looked at his clock and noticed we’d went over time, was pleased to say that he had passed me. All through the exam he was very easy to talk to and helped me through on anything I was struggling with.
