The certification question on an offshore panel is the same one asked onshore — zone, gas group, temperature class, protection concept — and it is covered on our Ex-rated panels page. This page is about what offshore adds on top, because that is what decides the design. Deck space and weight come first, both rationed, and they frequently push the build towards a purged enclosure holding standard components densely rather than a larger increased-safety one. Heat rejection is the twin problem: a sealed panel in salt air cannot use filtered fans, so cooling is a vortex unit, a certified air conditioner, or keeping dissipation down. Then the two constraints that strand equipment on a deck. Purge air has to be genuinely reliable, since losing it shuts the panel down. And the lifted dimension has to suit both the crane and the route to the final position, because a panel that will not pass the module opening stays where it was landed.
The more of this you send, the closer the first quotation lands.
| Certification basis | Zone, gas group, temperature class and scheme — the same as any Ex equipment |
|---|---|
| Protection method | Ex p purged, Ex e increased safety, or Ex d flameproof |
| Purge supply reliability | Losing instrument air shuts a purged panel down |
| Deck space and weight | Both are rationed — they often decide the protection method |
| Internal heat load | Watts dissipated, since filtered fans are not an option |
| Cooling method | Vortex cooler, certified air conditioner, or reduced dissipation |
| Ambient temperature range | The certificate is issued for a stated range |
| Enclosure material | 316 stainless or GRP, with the operator coating system |
| Function | Motor control, instrument marshalling, control, or distribution |
| Lifted dimensions | Crane capacity, and the route to the final position |
| Cable entries | Certified glands matched to the offshore cable type |
| Documentation | Assembly certificate, drawings and the marking plate details |
| Sea transport and preservation | Packing, desiccant and preservation for the voyage and lay-down |
| Offshore commissioning | Whether vendor attendance offshore is in scope, and the POB constraint |
