6 anchor piles for FPSO Mooring system

6 ANCHOR PILES FOR FPSO MOORING SYSTEM

In 2018, the CAPE VLT-80 was used to upend and install six 60 inch diameter anchor piles with a length of 30 meter, in a water depth of 26 meter.

Using the CAPE VLT, no seabed installation frame was required, which is expensive, complex to handle and takes a lot of deck space.

With the CAPE VLT, the piles were placed in record time. As the piles had to finish below the mud line, an impact hammer with a follower was used after the piles had reached stable penetration.
