Deep Panuke Project

M & A Engineering Ltd won the contract to design, manufacture and utilise specialised pipe machining equipment for the ‘Deep Panuke Development’; Nova Scotia.

 

The ends of some 204 ‘Buckle Arrestor Pipes’ had to be machined over a length of 250mm from a nominal diameter of 565.4mm to 559.0mm . The main criterion of the task however was to maintain the wall thickness tolerance. Each pipe could be up to 5mm out-of-round and so the machines had to be designed to follow the profile of each individual pipe. A blended 1:4 run-off was also required between the machined diameter and body of the pipe.

Six machines were manufactured and, with the associated hydraulic drive equipment,

transported to Italy where the machining work was carried out.

 

The Task Ahead

 

 

The external weld bead had to be ground flush prior to machining.

Great care was required to ensure the pipe wall thickness was not undercut.

Each pipe had both ends worked on simultaneously.This ensured a quick turn-around

for moving the pipes onto the shot blast and coating processes carried out by the customer.

Production targets were critical as the pipes were required in Nova Scotia before the weather closed in towards the end of the year.

 

M & A successfully surpassed production expectations and the project was completed ahead of schedule and to the complete satisfaction of the customer.
