Lessons Identified

A number of lessons arise from this incident:

1. The procedure for identifying and recording 3rd party potential DROPS must be clearly communicated.

2. Procedures for the removal of obselete equipment should be improved.

3. 3rd party contracting companies must have their own procedures in place for safely securing equipment at height.

4. All task risk assessments and STOPs for routine drilling activities to be reassessed for potential dropped/falling objects.

5. Independent audit of DROPS procedure

6. Raise awareness of company DROPS procedures, vessel modification procedures.

7. Consider implementation of exclusion zones around rotary table for certain drilling operations.
