Description: | A routine inspection of lifeboats on an offshore installation revealed extensive corrosion to the Davits (lifeboat holding equipment). The corrosion was discovered on the inner side of the beams local to the top sheave.
Further examination revealed more scale that had previously been painted over. Thorough NDT (Non-Destructive Testing) was carried out on all structures to assess integrity as a consequence of which the davits along with lifeboat were deemed unfit for use.
The davits affected were an older type (`A' frame) of davit, fabricated using two `C’ type steel beams back-to-back. |
Specific Equipment: | No details available. |
Lessons Learnt: | `A’ frame davits are prone to structural corrosion especially behind the top pulley/sheave, due to possible retention of water. |
Task Description: | No details available. |
Recommendations: | - Conduct routine visual examinations of all `A’ frame type davits.
- Include the above visual examinations in the annual lifeboat maintenance routines.
- Although the new design for davits (box type structure) is not prone to similar types of corrosion, they should also undergo a periodic structural examination.
