As part of an upgrade to berthing dolphins at the Cape Lambert A Berths, MES was commissioned to undertake a detailed geophysical survey to develop a geological and seafloor feature model for assessing pile foundation design and assessing seabed obstructions. The key objectives were to identify presence of chert, banded iron formation or other strong rock that may cause early refusal of driven piles as well as man-made obstructions such as decommissioned cut off piles on the seabed which could impact the positioning of the new piles and installation.
TECHNIQUES USED
- Deep marine seismic refraction
- Sub-bottom profiling
- Side scan sonar
