PSA investigation of lifting incident on Scarabeo 5

During installation of a hydraulic lifting cylinder on the catwalk machine on the drilling facility Scarabeo 5, one person sustained a serious shoulder injury. During the period 13 May -15 May 2007 the Petroleum Safety Authority (PSA) conducted an investigation of the incident on the drilling facility, which is located on the Kristin field where Statoil ASA is the operator. Our general impression following the investigation is that the incident was caused by deficient planning and deficient understanding of risk, among other things.


In connection with the installation of a hydraulic lifting cylinder on the catwalk machine on the drilling facility Scarabeo 5 on 11 May 2007, one person sustained a serious shoulder injury and was sent by SAR helicopter to the hospital in Kristiansund.

The incident occurred during installation of a hydraulic lifting cylinder weighing 1300 kilos and with a length of 6 meters (hereafter called cylinder), in connection with replacement of a defect cylinder. The installation was carried out using a temporary lifting assembly consisting of a chain hoist and associated lifting gear. Three persons were involved in the lifting operation at the time.

When the cylinder came into position above the notch, the fiber sling came loose from the cylinder resulting in the cylinder falling about two meters.

A coupling block was welded on to the cylinder about 2.8 meters above its bottom and protruding 20 cm from the cylinder. This coupling block hit the person's hard hat and then his shoulder.

Our general impression following the investigation is that the lifting operation was characterized by deficient planning and deficient understanding of risk.

Identified non-conformities:

  • Deficient facilitation of the work.

  • Deficient risk identification.

  • Deficient work supervision - roles and responsibilities.

  • Person under hanging load.

  •  

We were informed that for future replacements of this type of cylinder, a separate clamp will be made and mounted on the cylinder, and the lifting sling can then be fastened to this.
