We've been watching/listening again. Theres a Global Hawk in the area now as well.
The third issue is very specialised and involves a wee bastard called Cladinosporum Resinae (the useless shit I remember). It’s a fungus that lives on tank walls and feeds on the hydrocarbon in the fuel but needs water so usually is found at the boundary between fuel and water in the sump. It breaks up and can clog filters. Draining the water helps but this stuff can live on water dissolved in the fuel so chunks of Strontium are bolted into the tanks which pisses on its fuse apparently.
Haven't heard Cladinosporum Resinae for a while. We used to have to dip the tanks and test for water at the bottom of the tanks if any was found there was another test to look for Cladinosporum Resinae but it lives in the interface between the fuel and water so is very hard to get to.

Prior to and on completion of refuelling on offshore installations the fuel from the hose is sampled by these babies. Fuel is squirted through the capsule by a syringe and if water is present the yellow core goes dark green. The deck crew show the result to the helicopter crew.
Can be a right bastard to get a good result when it’s lashing with rain.
