NOPSEMA recently issued a safety alert following an incident which involved a lifting operation on an offshore facility and one worker was injured and transferred onshore for medical treatment.
The incident involved a monorail hoist dropping a 500kg piping spool (including ancillaries) when its beam trolley, chain hoist and suspended load overran the end-stop.
NOPSEMA deployed inspectors to the facility to investigate, and preliminary findings identified that the monorail hoist was not fit for purpose, specifically the monorail end stops and beam trolley width.
In addition to this finding, the beam trolley had been modified outside of the management of change processes and the lift plan was not followed, resulting in unsafe operation of the monorail hoist.
Recognising an immediate threat to the health and safety of the workforce, NOPSEMA issued a prohibition notice requiring the duty holder to cease the use of ‘any beam-and-trolley type lifting appliance’ for the ‘lifting of any kind without the express and written approval of the facility Offshore Installation Manager that risk has been appropriately managed’.
NOPSEMA is monitoring the duty holder’s internal investigation including the identification of root causes and remedial actions.
NOPSEMA has previously drawn industry’s attention to the real and significant threat from lifting operations, dropped objects and crane failures to the offshore workforce.
The regulator said all lifting equipment must be designed, installed, inspected, and maintained in accordance with the relevant standards and by a competent person, and highlighted a number of key lessons:
