Eligibility & requirements
- Spanish Bachillerato (upper-secondary leaving certificate) or equivalent.
- Maritime medical fitness certificate.
- Sea-internship phases embedded in the degree.
- Spanish language; English required for STCW certification and international employment.

Frequently asked questions
What is the DGMM in Spain?+
The Dirección General de la Marina Mercante (DGMM), part of the Ministry of Transport, is responsible for certifying merchant officers, registering ships, and implementing maritime safety and STCW regulations in Spain.
Are Spanish maritime qualifications valid across the EU?+
Yes. Spanish STCW CoCs issued by DGMM are recognised across EU/EEA member states under the relevant EU directives, though individual flag states still require their own endorsements.
The realities of life at sea
Things the recruitment brochures leave out — and every candidate should know before committing.
Shore leave is disappearing
Modern container and tanker ports turn ships around in 8–16 hours. Officers can arrive in Rotterdam, Singapore or Houston and never step off the gangway. For months at a time, the ship is the entire world.
Paperwork has overtaken seamanship
ISM, MLC, ISPS, SMS — every incident generates a new form. Industry surveys show senior officers spending 2–3 hours daily on documentation. Many describe it as the most demoralising part of the job.
Mental health is the unspoken crisis
Confinement, isolation, repeated separation from family, and a culture that equates stoicism with professionalism combine into a serious mental-health risk. Seafarer well-being surveys consistently record depression and anxiety rates well above land-based populations.
Your contract governs more than you think
The flag state, not your nationality, determines most of your working rights at sea. A Filipino officer on a Liberian-flag ship managed by a Greek company operates under Liberian law and ITF-negotiated terms — not Filipino labour law.
No employer pension — ever
Most seafarers are employed on fixed-term contracts through manning agencies. There is no employer pension contribution as standard. Retirement planning is entirely self-managed, yet most young officers spend freely during high-earning years.
Re-entry shock is real
After 4–6 months aboard, returning home is not just a relief — it is a social recalibration. Children have grown; spouses have adapted; social groups have moved on. Officers repeatedly describe feeling like a visitor in their own home.
