310msw (1020fsw) Rated 170ton Piled Anchorage System PROJECT
Delivered design and detailed engineering for four different types of 36m long vertically piled 170ton in air weight subsea transition anchorage structure.
The Piled Anchor Blocks (PABs) have operational water depths ranging from 280msw to 311msw and with subsea slopes ranging up to 17deg.
PABs are designed to include 40ton post installable weight blocks to keep the overall system in air weight within vessel crane capacity and also to increase the in water weight of the PABs during in-place operational conditions.
