The international certificates of competency for deck and engine officers are valid for five years. Most of the certificates of proficiency are also valid for five years. The certificates of competency for crew are valid until further notice. There are different options for the revalidation of the certificates depending on the certificate of competency or proficiency.
The training required for issuance of Certificates of Competency (CoC) and Certificates of Proficiency (CoP) must be provided by a Maritime Education and Training (MET) provider approved by Finland. Mainly these approved MET providers are located in Finland. On the basis of training conducted not in Finland, a CoC or CoP is sought from the authority who approved that training, usually the maritime authorities of that country.
