Description: | The Neptune platform TEMPSC and davit were being routinely checked for operability during a visit to the normally unattended installation, (NUI). The release system is hydraulic, as opposed to the standard mechanical type. It was discovered that the hydraulic accumulator, (bladder type), which is required for release of the holding brake, did not possess any fluid pressure or charge pressure. As a consequence the TEMPSC could not have been released from the davit. |
Specific Equipment: | No details available. |
Lessons Learnt: | · The hydraulic system pressure had decayed to zero. Regular checks must be carried out.
· There was no pressure indicator on the hydraulic system that could provide immediate visual indication of the system status.
· Without sufficient hydraulic pressure, the TEMPSC cannot be released from the davit. There is no override to the hydraulic release system. |
Task Description: | No details available. |
Recommendations: | · Operators should review their davit release systems in order to satisfy themselves that they are at all times able to affect a launch of their TEMPSCs.
· Manufacturers agreed modification to this system is the inclusion of a check valve and pressure indicator on the hydraulic pump discharge line to the accumulator. |
