Suction piles have been used effectively as mooring anchors and foundations since the 1990s. Suction piles (also called suction caissons or suction anchors) are a long steel cylinder topped with a pile top or cap. The cap comprises valves to assist with embedment as well as connections that differ depending on the use of the pile.
Franklin Offshore subsidiary CFE Engineers Asia has completed fabrication and load-out of 12 suction piles for Chevron’s $4 billion Jansz-lo compression project offshore Western Australia.
Hanwha Ocean (ex-Daewoo Shipbuilding & Marine Engineering) commissioned the mooring piles after securing a $545 million construction contract from Chevron in early 2022 for the project’s field control station for the Jansz-Io compression project.
The suction piles, weighing almost 4,500 metric tons in total, were manufactured in Singapore and lifted using Franklin Offshore's NEXUS synthetic sling system.
