| GWO Wind OEUK with Chester Step Test | Up to 2 years |
| Chester Step Test | Per operator requirement, typically up to 2 years |
| Seafarer medical certificate (STCW) | Up to 2 years |
| Smoke diver / ERT | Follows your OEUK Medical |
| Mast & Pole Certificate | Per Swedish requirements, agreed on the day |

| INEOS health certificate (DANOP) | Per company requirement |
| Petronas Malaysia | Per Petronas requirement |
The doctor can set a shorter validity than the standard if there are health conditions that should be followed more closely. That is not a rejection, but an agreement to look at it again sooner.
It is always agreed with you on the day, and you are told why. You will not be sent home with a shorter certificate and no explanation.
For the seafarer medical, a shorter validity may also apply to applicants under 18.
Vattenfall, INEOS and Petronas set the validity on their own certificates. It can be shorter than the industry certificate, and it is stated in the mobilisation letter or on the certificate itself.
If in doubt, check the certificate or call +45 70 60 33 38. We can usually look it up.
Book a couple of weeks ahead. That way you are not left without a valid certificate if a supplementary examination is needed.
If you change operator, a different certificate may be required even though your current one is valid.
That is not a problem. You simply need a new one, and in many cases it can be done the same day.
