Applicants have to be at least 18 years old and must pass an initial diving medical examination no longer than three months prior to the start of the course to ensure that they are medically fit to dive.
Diving medical examinations can only be carried out by approved medical examiners in Denmark. A list of the doctors approved by the Danish Maritime Authority can be found here.
For students from outside of Denmark, the medical examination can be arranged by the diving school.
As professional diving requires a high degree of physical and psychological fitness, applicants are also required to pass a physical fitness test with the following tasks:
- 1000m surface swim without fins in under 30 minutes
- 2.5 km run in under 15 minutes
- 25 m underwater swim without fins (fully submerged)
- 1 minute breathholding in swimming pool at 2 m depth
