Chief Engineer interview questions

I start with accurate data: daily soundings, flow meter readings and consumption reports that match each other, so I can see trends and catch problems early.

The main areas I work on are:

• Main engine condition: correct fuel injection and combustion, clean turbochargers and scavenge air coolers, and regular performance measurements compared with the shop test.
• Hull and propeller: I report to the company when performance data shows fouling, so cleaning can be planned.
• Auxiliary consumption: running the right number of generators, avoiding unnecessary pumps and heating, and steam plant efficiency.
• Speed and voyage optimisation together with the Master, following charterer's and company instructions.

I follow the ship's SEEMP and the data collection for the IMO Carbon Intensity Indicator (CII), and I make sure the engine crew understands why efficiency matters, so they do not run equipment out of habit.

I keep the engine room ready at all times, but before an inspection I check the items inspectors look at most:

• Emergency equipment: emergency generator, emergency fire pump, quick-closing valves, emergency stops, fire dampers and fixed fire-fighting system, all tested and working.
• Pollution prevention: oily water separator, oil content meter and 15 ppm alarm working; Oil Record Book entries matching the soundings; no unofficial connections; MARPOL Annex VI documents, fuel samples and bunker delivery notes in order.
• Machinery condition: no leaks, good housekeeping, guards in place, bilges clean and dry.
• Records: PMS up to date, overdue jobs explained, certificates of class items valid.
• Crew: engineers able to demonstrate starting the emergency equipment and explain their duties.

I accompany the inspector myself, answer openly and never try to hide a defect. A known defect with a repair plan is acceptable; a hidden one destroys trust.

The priority is restoring power fast and safely, because the bridge has lost propulsion or steering.

1. Confirm the emergency generator has started and supplies the emergency switchboard: steering gear, emergency lighting, communications.
2. Inform the bridge immediately and keep the communication open, so the Master can anchor or use other measures.
3. Restart a main generator: if standby generators did not start automatically, start one manually, check it is safe to close the breaker and restore the main switchboard.
4. Restart essential services in sequence: lube oil, cooling water and fuel pumps, steering gear pumps, then prepare the main engine.
5. Find the cause before loading the plant again, for example a fuel supply problem, a dirty filter, a tripped breaker or an overload, to prevent a second blackout.

Afterwards I record the event, report it to the company and review the causes. Blackout drills help the engineers react quickly when it really happens.

Under MARPOL Annex VI, ships in a sulphur ECA must use fuel with not more than 0.10% sulphur. The ship must carry a written fuel changeover procedure.

My steps:

1. Plan the time of changeover with the Master, based on the procedure and the system volumes, so that the changeover is fully completed before entering the ECA.
2. Prepare the system: check the compliant fuel tanks, the viscosity and temperature control, and the lubrication oil compatibility with the engine maker's recommendations.
3. Change over gradually, controlling the temperature change in the fuel system to avoid thermal shock and fuel pump sticking.
4. Record in the logbook the date, time, ship's position and the quantities of compliant fuel in each tank at the start and completion of the changeover, as MARPOL requires.

I also check the fuel's viscosity, because low-viscosity fuels can cause pump wear or problems starting the engine.

I see the Second Engineer as my right hand: he plans and runs the daily work and I support him with priorities, spare parts and decisions. I hold a short daily meeting to agree the plan, safety issues and any problem from the night.

I give each engineer clear responsibility for their equipment and expect them to know it well. I check the work, but I do not micromanage: people learn when they own a job.

For juniors and cadets I make sure they get proper familiarisation and real training, not only cleaning jobs. I involve them in overhauls and ask them to explain systems to me, which shows quickly what they understand.

I also look after the team: fair workloads, respect for rest hours and a working atmosphere where people report mistakes early. In my experience, an engine room where people are afraid to report problems is an unsafe engine room.
