You need an able seafarer engine certificate under STCW III/5. First you must hold an engine-room watch rating certificate under STCW III/4. You also need STCW basic training and security-awareness training.
How much sea service do I need for the able seafarer engine certificate?
After you qualify as an engine watch rating, you need approved seagoing service in the engine department of not less than 12 months. The time is reduced to not less than 6 months if you complete approved training.
