To accommodate a new 170m long vessel, Citic Pacific required the port’s berthing pocket to be deepened from 10m to 11m.
The existing rock revetment had been sized for smaller vessels and needed stabilisation
Subcon designed a bespoke stabilisation and scour solution for the above conundrum. The design was done in house and scale testing of the solution was done at the University of New South Wales’s Water Research Laboratory.
A total of 3000m2 of mattresses were fabricated, transported by road to the remote site and installed.
