This project, based on the thesis Human-Made Ocean: Exploring the Possibility of Offshore Oil and Gas Platforms, envisions a future where decommissioned offshore platforms are repurposed to support marine environments and human activities sustainably. The project envisions a future where these industrial structures can coexist harmoniously with nature and society, achieving a balance between human intervention and the preservation of natural life. The concept addresses both global and local needs in a world transitioning away from oil dependence. Globally, the project leverages the widespread distribution and natural cooling benefits of offshore platforms for decentralized data cloud storage, addressing issues like privacy, energy efficiency, and environmental impact. This global prototype aims to transform these platforms into data storage hubs to support sustainable industry. Locally, the project focuses on a community-centered prototype for Sungai Apit, on the island of Sumatra, Indonesia. Historically, offshore platforms provided economic benefits through oil extraction but did not integrate well with local communities. By deconstructing and reassembling these structures, their prototypes aim to create spaces that protect mangrove forests and support local economies. Human-Made Ocean advocates for site-specific, flexible strategies that consider environmental, economic, social, and cultural factors. By transforming industrial relics into sustainable assets, the project enhances ecological sustainability and community resilience. It demonstrates how reusing offshore platforms can provide wide-ranging benefits, fostering a holistic and inclusive approach to marine and urban development. This unified vision shows that global and local perspectives can coexist within sustainable projection for the future.
