Rope Access Team Member Inadvertently Entered Sea

The first section of clamp had been successfully lowered into position below the leg mooring ring.

One team member ascended to the spider deck to prepare the second clamp section for lowering, leaving one over-side team member on the mooring ring.

The first team member partially rearranged one of the ropes to improve access for lowering the second clamp section.

The second team member remained on the mooring ring and positioned himself to access a chain block, changing over ropes to do this.

The second member transferred onto a rope loop, which unravelled when full weight was applied, resulting in an unplanned descent from the mooring ring onto the water surface.

- No injuries were sustained.

- Individual remained connected to ropes at all times during this unplanned descent.

On contact with water his lifejacket activated and he was picked up by the on-scene daughter craft within 2 minutes

Causes:

Inadequate communication between team members: The temporary change in status of one of the rope systems was not effectively communicated between the team members.

Improper decision making or lack of judgement: Individual connected to a rope which he had not adequately confirmed as having sufficient tension to apply his full weight.

Supervision:

- Inadequate monitoring of ongoing work.

- Standards of performance missing or not enforced.

- Inadequate change management.

Routine activity without thought: Over-reliance or overconfidence using the mooring ring as a working platform.
