Critical Contributing Factors

Procedures not followed

• JSA 145 was not used/referenced prior to the job.

Failure to secure

• The Side Door Elevator not securely latched

• The safety latch lock pin was installed incorrectly. Pin was found

inserted behind the latch handle.

Lack of clear responsibility

• No specific actions assigned to a responsible person.

• Multiple/different rig crews were responsible for latching elevator.

• Practice of only drilling contractor to operate around rotary table

Critical Contributing Factors

Breakdown in communication between work teams

• Rig crews changed tasks throughout the job. This occurred during

the 6 joints that were laid down, not standard rig floor practice

• Change of duties on the rig floor should be managed

Insufficient training

• Lack of training and underpinning knowledge of rig crew to check

safety pin is properly installed and elevator latch is completely

closed.

Equipment deficiency

• Frank’s had carried out retrofit per Varco Service Bulletin 17 but

not Service Bulletin 47

• Frank’s service bulletin 23 and subsequent retrofit 38 did not

address Varco SSD series

Conclusions

The root causes of this incident;

• Incorrect latching and installation of safety pin by

floorman.

• Failure to carry out a required retrofit update to the

elevator. This would have avoided the incorrect

installation of the safety pin, which was a

contributing factor leading to the incident.

• Communication of responsibilities (casing crew to

operate own equipment)

Mitigation

• The subject SSD elevator was immediately pulled from service

• Frank’s identified that there are five Varco Model SSD Side Door Elevators in inventory. All are taken out of service.

• March 2013, Frank’s issues Retrofit Notice RF – 229 – Following incident, detailed instructions required to install Latch

Lock Safety Pins sent to the three Frank’s locations where Varco Model SSD Side Door Elevators are located.

• All other side door elevators models worldwide have been subjected to checks – Ensure fit for purpose per Frank’s Service Bulletin 177

Other mitigation methods: Hands Free Systems.

• Use of automated systems including ;

- remote tong technology

- Hands free technology (elevators) used in conjunction with remote tongs.

- CRT systems

• All of which take away the manual handling and need for people on the rig floor
