What you need to perform it
Primary qualification
- No dedicated STCW certificate of proficiency: this is the engine-department entry position, accessible with Basic Safety Training and a valid medical certificate.
- Spain: signing on with the Seaman's Book (Libreta de Inscripción Marítima) and crew dispatch per DGMM requirements (verify current requirements).
Basic STCW
- STCW A-VI/1 Basic Safety Training (survival, fire fighting, first aid, personal safety and social responsibilities).
- Security awareness training A-VI/6-1 and a valid seafarer medical certificate.
Specific courses
- Onboard safety familiarisation and engine-room-specific familiarisation (ISM Code).
- Safe handling of cleaning chemicals and degreasers (safety data sheets, PPE — company training).
- Confined spaces and permit-to-work before entering bilges, tanks or crankcases.
Indicative experience
Entry position: no previous seagoing service required. As a guide: 6–12 months as wiper before promotion to oiler/engine-room watch rating (STCW III/4), depending on company policy and flag.
Observations
First rung of the engine ladder: Wiper → Oiler (III/4) → Able Seafarer Engine (III/5). Those who make the most of the job leave knowing the ship better than anyone of their intake. Bilge cleaning has direct MARPOL implications: not a drop of oil overboard, and transfers are recorded in the Oil Record Book by the officers. Attitude in this position defines the career: chief engineers promote the ones who ask questions.
What this role does
Entry position of the engine department: plant cleaning, workshop support and learning the ship. Its real value is formative — identifying lines, valves and equipment while cleaning is the best engine-room school there is, and it feeds the pipeline of oilers and engine ratings.
