Heavy lifting operations for Singapore’s land reclamation project

Specialized Heavy Lift and Transport Solutions for Singapore’s Offshore Island

As explained in a statement by Mammoet, the land reclamation project Pulau Tekong Polder supports the transformation of Singapore’s landscape. This innovative initiative has created the country’s first polder, reclaiming approximately 800 hectares of land. The Housing Development Board (HDB) is leading the project, while the Boskalis Penta Ocean Joint Venture (BPJV) is responsible for the construction.

Innovative Land Reclamation Method

Unlike the conventional method of land reclamation, which involves dumping sand, the project utilizes the novel „Empololdering“ method. This technique involves constructing a dike around the designated area, from which water is then pumped out to create a low-lying land area, the polder. The dike protects the newly reclaimed land from the sea, while a network of drains and pumps controls the water level. This approach significantly reduces the need for fill material, thereby lowering construction costs.

Complex Salvage Operations

As part of the project, a rainwater catchment basin was established in the polder to store excess rainwater. Various floating devices and barges were used to deepen this basin. Upon completion of the work, the equipment and barges needed to be salvaged and relocated to ensure continued operations. In total, twelve barges weighing between 680 and 990 tons had to be salvaged, transported over a newly constructed access road to the dike, and subsequently released back into the sea.

Experienced Partners for Challenging Tasks

Mammoet was selected for its extensive experience in similar projects, particularly for the use of airbags and winches during barge launches. A team of local and international experts was assembled to bring the necessary expertise to the project.

The salvage operations were carried out in carefully planned phases. Mammoet deployed 68 airbags and four winches with a capacity of 60 to 85 tons to salvage and launch each barge from the rainwater catchment basin. Precision and careful management were crucial for the safe recovery of the barges.

Precise Execution and Impressive Results

The airbags were placed under the bow of each pontoon, and after connecting all cables, two winches pulled the barges out of the water until 18 jacks were positioned. After the salvage, the barge was lifted to remove the airbags, and SPMTs (Self-Propelled Modular Transporters) were used to transport the barges to the launch site. The launch process was repeated for all twelve barges.

Despite unforeseen weather conditions, Mammoet adhered to a strict schedule, demonstrating flexibility and commitment. The results of the operation were remarkable: Mammoet not only met tight deadlines but also played a central role in a project that expands Singapore’s landmass.

„We are very proud of our role in the Tekong Polder project. By leveraging our global expertise, we have contributed to strengthening Singapore’s geographical presence,“ said Anandan Lokantham, Sales Director at Mammoet Projects AMEA.
