A fatality occurred in January 2023, on an offshore worksite, whereby a worker fell overboard because of a dislodged section of polymer grating, commonly used in the offshore industry.
What happened?
(This incident did not occur on an IMCA Member's facility.)
On a jack-up rig in transit, a crew member was reported missing, believed to have gone overboard.
The missing crew member finished their shift at 18:00 and was last seen just after 19:00.
During the investigation it was identified that a section of polymer grating outside an accommodation door, used to provide a means of access and egress, had become dislodged, thereby exposing employees to the hole in the decking area.
It is understood that the lost crew member must have fallen through this hole.
Further inspection by the UK Health and Safety Executive (HSE) revealed that further multiple polymer grating systems had been installed similar to the one that was dislodged and were found to be unsecure.

Actions
There is potential for a similar incident to occur on IMCA members’ vessels or installations, in work areas such as towers, reels, cranes and access platforms, or ROV systems, and on external walkways.
- Identify areas on the vessel where this kind of grating is found (Glass Reinforced Plastics (GRP) or Fibre Reinforced Plastics (FRP)) and ensure that the fasteners are installed as per the OEM instructions.
- Ensure the possibility of such grating coming loose and falling, is included in existing dropped object checklists.
- Update planned maintenance systems as required.
