mmhe q6 dredging (west)

The Construction and Completion of Seabed Deepening at MMHE Quay No. 6 in Pasir Gudang, Johor, was a critical project aimed at providing an adequately deepened berthing pocket for load-out barges and vessels. 

The project’s scope included the excavation and dredging of both soil and rock from the seabed to achieve a depth of -10 meters Chart Datum (CD). This involved dredging to the specified design layout and levels, followed by the disposal of dredged materials at approved dumping grounds located at Ramunia Shoals, approximately 37NM from the site.

Given the concurrent operations at the shipyard, SYS was required to coordinate access for ongoing activities, including works, load-outs, and fabrications, as directed by MMHE. The dredged volumes consisted of 131,132 cubic meters of soil and 18,000 cubic meters of rock. Notably, as the depth increased, the dredged materials became more challenging, with rock samples tested at Geolab laboratory revealing hardness levels necessitating rock blasting.
