Bananas are different though - they are often packed warm, and brought directly to the ship. They are also kept at +14degC. This means the refrigeration needs to work harder.

We are now looking at as much as 20kW to cool that container when it comes onboard, and 8kW to maintain the temperature. We've jumped to 8MW at least! That's changed what you are doing in the engine room.

Each of the 5 generators on the Emma Maersk is around 4MW. You are now running 3 generators just to keep the ship running in port!

Worse still, the shaft generator (the thing that recovers power from the main engine) is only 8.5MW. You are now having to run extra generators. Not economical. But doable.

So where does all that heat go from the refrigerated containers? The air. That's fine above the hatches. But what about below the hatches? Well, you need fans. And a lot of them.

No container ship I worked on had enough below hatch ventilation to handle 100% bananas. 100 containers dumping 8kW of power under a hatch is a lot. Total guess, but I don't think you'd manage more than 75% of reefer being at full load.

So I think at best... we have 750 * 120k = 90 Mega Bananas. Enough for everyone in the UK and me.

How do shipping companies handle this? Well, there are actually special banana ships - they are open hatch and can easily handle the load. Anyway, hope that was fun :)

This is what happens when you just multiply containers by how much you think is in them.

For those of you interested in what the engine room of a container ship looks like, I posted some pictures last year:https://twitter.com/cybergibbons/status/1176182170546835456 …

Cybergibbons! (Project Zero Hounslow) @cybergibbonsA couple of days ago, I talked about an "engine the size of a house". It's a not an exaggeration. What are the engines and other equipment like on a container ship? This is a 66,000gt ship, approximately 280m long. Rated about 5500 TEU. This is the top of the main engine. pic.twitter.com/v8CFDrClpfPrikaži ovu nit63 proslijeđena tweeta 568 korisnika označava da im se sviđaPrikaži ovu nit
All I see is a massive climate death machine.

Odgovor korisnicima @quinnnorton @cybergibbons
Yeah it is. I wish ships hadn’t wind-foils or sails or something. If the entire fleet of container ships were 10% more efficient it would make a big difference.
