The Chilime
HEP has been significant for us in that we were responsible for
all aspects of the penstock pipe. This included design and
factory pressure testing of the bifurcation joint. We also
used the opportunity of the contract to design, manufacture and
instal the gates to review and improve our designs for roller and sliding gates.
One of the roller gates, 4m x 5m in size, was also the largest we have
made. |
