As our swimming action in front of Chevron's ship enters its third day, we've been stopping the deepwater oil drillers for a week now.
First the portaledge on their anchor chain, then the pod, and now swimmers in the water.
And we're still continuing.
The white board next to the mess room has all the rota details: two boat crew and two swimmers at all times, running four-hour shifts day and night. Pretty much everyone on the Esperanza is in the sea at some point.
The water is pretty cold - as you'd expect on the 'Arctic Frontier' - but fortunately the immersion suits keep you warm. Well, most of the time.
But while the temperatures might be low, our morale is high and we're all happy to be able to stop this reckless deepwater drilling, trying to do our bit to push companies like Chevron and our politicians to go beyond oil.
It's not only a case of protecting the environment from a catastrophic oil spill like we saw in the Gulf of Mexico this summer, it's also about stopping climate change. If we drill, extract and burn the oil in places like the west of Shetland we risk an average rise in global temperatures of between five and six degrees.
That's why we're here, trying to stop Chevron and it's 228-metre drill ship from continuing this madness. We're holding out as long as we can, but just wanted to say thank you for all your messages of support, on Facebook, Twitter and here on our website.
