Coy set to float first made in nigeria air boat modular refinery

I think there may be some confusion here.

Firstly, "Coy" is not a well-known term in the context of airboats or refineries. Could you please clarify what you mean by "Coy set to float"?

Secondly, Nigeria is a country in West Africa, and while it has a rich oil and gas industry, I'm not aware of any "air boat modular refinery" being built or operated in Nigeria.

Lastly, airboats are typically used for transportation or recreation on water, while refineries are large industrial facilities that process crude oil into various petroleum products. They are two very different things!

If you could provide more context or clarify what you mean by "Coy set to float" and "air boat modular refinery", I'd be happy to try and help you with your question.
