Wave energy developer Carnegie Wave Energy has retrieved the second CETO 5 unit and deployed CETO unit #1 in its place last week.
CETO 5 Unit #2 was retrieved by disconnecting the Unit from the seabed foundation, using the hydraulic “quick connect” technology. CETO 5 Unit #1, which had been inspected and overhauled over the past months, was then installed in the former position of Unit #2, the company explained.
This operation was carried out in the higher sea state conditions that tend to prevail off the Western Australian coast between July and September.
Carnegie Chief Operating Officer, Greg Allen, said, “The successful retrieval of the CETO units after record breaking operational hours has validated Carnegie’s installation and retrieval methodology. We have shown that our units are able to survive and operate over a sustained period of time in a variety of weather conditions, addressing the key industry challenges of survivability and reliability.”
The Perth Project has now been operating for over 13,500 cumulative hours. The learnings from these operation and maintenance activities are being fed into the design phase for the CETO 6 Project at Garden Island, Carnegie added.
