Certificate of Competency

Certificate of Competency issued by a flag-state Administration under the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) certifying that the holder is qualified for the assigned deck or engine rank. The CoC is the foundational document for officer service worldwide. It carries an STCW endorsement to confirm cross-flag recognition. STCW Reg. I/2 sets the standards; revalidation is required every five years under STCW VIII/1 with continued professional competence demonstrated through sea service or refresher training.
