What you need to perform it
Primary qualification
- STCW Regulation III/2 Chief Engineer certificate of competency (management level) for ships of ≥ 3,000 kW, or III/3 for 750–3,000 kW.
- Spain: professional title of Chief Engineer of the Merchant Navy (Royal Decree 973/2009), with attributions without power limit on Spanish merchant ships.
- Endorsements per ship: V/1 for tankers (advanced cargo level where duties apply), V/3 (IGF Code) on ships using low-flashpoint fuels.
Basic STCW
- A-VI/1-1 Personal survival
- A-VI/1-2 Fire fighting

- MARPOL Annex I and VI: 15 ppm separator, ORB and SOPEP/SMPEP plan

Indicative experience
STCW III/2: minimum 36 months' seagoing service as engineer officer, of which at least 12 with second-engineer responsibility. Under the Spanish route, the Chief title additionally requires the second-engineer time set by RD 973/2009 (indicative, check the DGMM call).
Observations
Typical route: Engineer Officer (III/1) → Second Engineer (III/2) → Chief Engineer. Certificate class depends on propulsion power (750–3,000 kW / ≥ 3,000 kW); five-yearly revalidation. Naming note: Spanish 'Jefe de Máquinas' = Chief Engineer.
