THE SOLUTION

Traditionally maintenance is not done on Corroded Contact Areas between pipe supports and pipelines due to the High Safety Risk resulting in Production Downtime and Cost. In order to gain access to the contact area, vertical displacement of the pipe or piping system from the pipe support is required.     

A SAFE Engineered Jacking System allowing access to Multiple Work Areas while the equipment is in Operation provides the solution. A combination of JAKU ARM JACKS, rated at a 6000 kg safe working load each, are utilised in achieving the required vertical displacement of selective or multiple product lines. 

The patented* jacking equipment achieves a vertical lift of up to 80 mm, sufficient to perform all inspections (NDE, Visual) and maintenance / improvements. Initial lifting (break away) is done remotely to avoid any personnel exposure in case of a resulting leak in suspect contact areas. Mechanical lifting follows the initial breakaway. The piping system gets furthermore vertically secured by means of an engineered double lock-out system on the jacks thereby not creating a suspended load (working underneath is safe).

IMPORTANT: 

Lifting is done whilst the pipelines are in production and we always emphasise to our clients that this is dangerous if not dealt with professionally. It is important to understand that a Jacking Solution is provided, contrary to the selling or rental of jacks. This solution involves thorough upfront engineering (piping stress analyses) to determine a safe jacking procedure and jack positions. It further extents to Safety Procedures, Trained Personnel, Potential Deviation Analyses, Emergency and Safety Management and strict adherence to Client Safety Procedures.
