Problem:

Original EPCM contractor had underestimated the requirements of servicing conveyor head pulley.

Conveyor head pulley was unable to be replaced by technician during major service.

Solution:

Trang performed a site visit and evaluation, and designed a certified service jig to allow access and replacement during major service.

Detailed stress analysis was performed, and detailed drawings were produced for fabrication.

Outcome:

• Allowed service technicians access to head pulley
• Created a safe working environment for technicians
• High risk elements identified during assessment
• Detailed engineering workshop drawings supplied
• It was found that preliminary information provided was structurally inadequate, and was treated as a 'Near Miss' by site safety
