Artificial Reef

Sisters' Islands, Singapore

This is a project in collaboration with a tertiary institution, to design and construct a seabed structure that will provide an additional 500 sq m of reef area for Sisters’ Island Marine Park in Singapore, as part of the reef restoration efforts to support existing habitat enhancement and conserve marine biodiversity.

The artificial reef, covering an area slightly bigger than a basketball court, will be formed by pre-fabricated concrete structures about 10m tall that will be sunk into the waters of the park. Occupying the entire water column from sub-surface to the seafloor, the structures, which are the size of three-storey terrace houses, are designed to provide numerous and unique habitat niches for a wide variety of marine life.

The artificial reefs are also designed to be self-sustaining, requiring minimal or no maintenance.

The structures, which would sit on the seabed without piling or major works, are conceptualised to minimise impact to the existing marine environment.

This project is estimated to be completed in Nov 2018. Construction method video may be viewed here.
