AI answer written only from the numbered passages below
Broadly yes for safety training: the industry bodies for the UK (Offshore Energies UK), Denmark (Dansk Offshore), Norway (Offshore Norge) and the Netherlands (Element NL, still trading standards under the NOGEPA name) have agreed to accept each other's safety training standards, so a worker trained to one North Sea country's offshore standard does not have to retrain from scratch for another sector 1. The condition is that the training body — OPITO or a national equivalent — is an approved provider 1. Medical fitness is treated separately: the Dutch sector does not use an identical certificate to the OEUK medical, but North Sea operators commonly expect an equivalent medical fitness standard, increasingly the IMHF 'Medical Fitness for Offshore Work' guideline, 7th edition of May 2024, before someone goes offshore or boards a helicopter to an installation 2. An OEUK medical certificate is normally valid for two years, shorter if a doctor recommends it, and Issue 8 of the OEUK Medical Standard took effect on 1 November 2025 2.
Not in the sources: The passages do not name which specific UK certificates (for example BOSIET or MIST) are recognised, nor the Dutch legal basis or any individual operator's own requirements.

Passage 1: North Sea training mutual recognition
Because the North Sea is split between several national offshore safety regimes, the industry bodies for the UK (Offshore Energies UK), Denmark (Dansk Offshore), Norway (Offshore Norge) and the Netherlands (Element NL, still trading standards under the NOGEPA name) have agreed to accept each other's safety training standards, so a worker trained to one country's offshore standard does not have to retrain from scratch to work in another North Sea sector — the training body (OPITO, or a national equivalent) still has to be an approved provider.

Passage 2: Validity and 2025 update
An OEUK medical certificate is normally valid for two years, shorter if a doctor recommends it. Issue 8 of the OEUK Medical Standard took effect on 1 November 2025 with updated examination requirements. The Netherlands sector does not use an identical certificate, but North Sea operators commonly expect an equivalent medical fitness standard (increasingly the international IMHF 'Medical Fitness for Offshore Work' guideline, 7th edition, May 2024) before allowing anyone offshore or in a helicopter to an installation.
