Interesting idea! I love how something as, well, out there as an oil rig can also be its own city-like ecosystem. It reminds me of this animation from the French school of animation Gobelins, and also of this poem by Pablo Neruda (though it's about freighters, and not oil rigs, but for some reason inspires the same 'vibe' as this seed) — it'd be cool to have some sort of psychological horror drama on the platform. Or maybe a simple ghost story would do nicely too.
