Port Maintenance Dredging Project


LOCATION: Pasir Panjang Terminal, Singapore
TYPE: Civil Engineering
Client: PSA Corporation Pte Ltd
CONTRACT VALUE: S$4.66 Million
COMPLETION DATE: Jan 2020
About The Project

Unlike conventional dredging operations, maintenance dredging is highly challenging due to the stringent requirement in dredging design depths. Having an allowable tolerance of only fractions of a metre, such operations by massive vessels are required to be carried out with immense care to avoid any over-dredging. The fact that it is carried out in one of the world’s busiest ports heightened the difficulty level of project planning and execution.

Maintenance dredging was carried out in an area of 280ha in Pasir Panjang Terminal within 9.5 months. State-of-the-art hydrographic survey equipment was adopted to address the strict hydrographic survey requirements set out by the client. Enhancement to our vessels’ depth sensory equipment enabled our team to perform maintenance dredging within the terminal up to the required accuracy. This allowed an economical and efficient dredging and dumping operation to be carried out, delivering the project within budget and on time.
