Failures of manually operated side-door elevators

Health and Safety Executive - Safety Notice
Department Name: Offshore Division
Bulletin No: OSD 4-2010
Issue Date: 7 June 2010
Target Audience: Offshore Industry
Key Issues: Unplanned opening of latch mechanism of side-door elevators lifting large diameter well casing from the horizontal position

Introduction:

There have been several serious dropped object incidents in offshore Northern Europe, including a near fatality, involving the use of manually operated side-door elevators to lift large diameter well casing. The incidents involved the unplanned opening of the elevators, during tailing-out or lifting of pipe from a horizontal position, allowing the load to fall. Investigation of the incidents has raised concerns about the safety of the latching mechanism.

Background:

The incidents came to our attention through the North Sea Offshore Authorities Forum (NSOAF). The Forum represents the offshore safety regulators of Denmark, the Faroe Islands, Germany, Ireland, the Netherlands, Norway, Sweden and the UK.

In view of the serious nature of the incidents, the Health and Safety Executive is issuing this notice to draw the attention of duty holders in UK waters to the issue, to the recommended actions and to the relevant UK regulations.

Action required:

Users of the equipment should ensure that:-

Users purchasing or renting new manual side-door elevators should verify with the manufactures or suppliers of the equipment that the design and manufacture of the equipment has been reviewed to ensure the safety of the latching mechanism. Users should satisfy themselves that the mechanism is safe and reliable for all foreseeable operations.
