The media have their heads up their holes with the reporting. There`s probably 6-10 portable compressors on site. Most will probably fill 2 tanks at a go, i.e. 2 fill whips (hoses). A 12 ltr tank takes about 10 -15 mins to fill properly. So with 10 comps (with 2 fill hoses) they can fill 20 tanks every 15 mins. Allowing time to to disconnect full and connect empties, add 5 mins to that, so 20 mins for 20 tanks. I hour for 60 tanks, 5 hours for 300 tanks. The divers also have to stay out of the water for a specific time to decompress nitrogen from their blood. The required time is calculated by using computerised dive tables or US Navy dive tables / British Sub Aqua Club dive tables (both come in hard copy).
There will be divers ready to place drop tanks before the rescue divers head in to the boys again. The lads will have learned a huge amount on the first rescue. They`ll know if more tanks are needed (I don`t know how many they have,300 is just a guess) and will have refined the extraction plan further. Don`t be surprised if they get the remaining 9 out today .
