Wicks B.V. is proud to announce the successful completion of a technically challenging project in Indonesia for the East Java Multipurpose Terminal.
A total of 1.7 million linear meters of Prefabricated Vertical Drains (PVDs) were installed within the footprint of a future 1.8-kilometer-long breakwater.
The works were executed from a barge in open sea conditions, with water depths ranging from 6 to 14 meters, and PVD installation depths between 6 and 28 meters below the seabed.
Despite these demanding conditions, an installation tolerance of just 15 centimetres was consistently achieved. This level of precision is essential to meet the installation criteria to ensure proper consolidation of the very soft marine clay.
To minimize PVD material losses, a semi-automatic system enabled underwater cutting of the drains just above the seabed.
Wicks B.V. developed a specialized marine installation method, combining modified PVD installation equipment with a barge specifically adapted for the project.
Specialized measurement techniques were implemented to provide real-time installation data. The operation relied heavily on RTK positioning, integrated with the powerful inhouse VOSS survey software.
Together, these elements provided a reliable and innovative marine ingenuity solution.
Working around the clock, seven days a week, a dedicated team successfully delivered the project ahead of schedule, driven by strong collaboration and excellent teamwork.
