Dive #97-99

 

Location: Eslövs Swimcentre, Sweden
Time down: 18:00 | Time up: 21:01 | Divetime: 181 min | Max depth: 4 meter | Average depth: 2 meter
Water temp: 20° | O² used: 400 litre | Dil used: 400 litre | Total RB divetime: 32h 56min

Three pooldives compiled into one logged dive. I don’t normally log a pooldive, but since this was connected to the RAID 40m Deco Rebreather course, I was under the obligation to log the dives. Did in total some 3 hours in the pool with lots of different error management, equipment handling and so on.

Dive #96

 

Location: Josefinelust, Kullaberg, Sweden
Time down: 13:34 | Time up: 14:34 | Divetime: 60 min | Max depth: 13.4 meter | Average depth: 6.3 meter
Water temp: 16° | O² used: 81 litre | Dil used: 54 litre | Total RB divetime: 29h 55min

Second dive of the day, after a nice lunch break on the beach we went in again for another 60 minutes. Nothing fancy, stayed more static at depth this dive, which resulted in less diluent used. O2 consumption was still low. I now have my 30 hours on the MkVI Rebreather, time to start that 40M Deco course.

Dive #95

Location: Josefinelust, Kullaberg, Sweden
Time down: 11:27 | Time up: 12:27 | Divetime: 60 min | Max depth: 16.8 meter | Average depth: 9.4 meter
Water temp: 16° | O² used: 75 litre | Dil used: 102 litre | Total RB divetime: 28h 55min

After the amazing wrecks of the U-boat massacre, a dive on the local divesite didnt look so interesting. Although, a dive. Did some training and tried to be really calm and relaxed. It paid of in terms of O2 consumption. 75 litres on 60 min, that is 1.25 lpm which by my standards are low. I usually use more like 2 lpm. Really warm in the water, a nice 16 degree C, compared to the 5 degree C we had in the Baltic Sea last week. Diveplan was 60 minutes, and 60 minute it was.

Dive #94

Location: S/S Nicomedia, Baltic Sea, Sweden
Time down: 16:15 | Time up: 17:06 | Divetime: 51 min | Max depth: 29 meter | Average depth: 19 meter
Water temp: 5° | O² used: 102 litre | Dil used: 180 litre | Total RB divetime: 27h 55min

Second dive on S/S Nicomedia, was much more relaxed, stayed pretty much on the deck of the wreck. I most definitely need to revisit these wrecks again, before the crumble down to a heap of steel.

Dive #93

Location: S/S Nicomedia, Baltic Sea, Sweden
Time down: 13:20 | Time up: 14:02 | Divetime: 42 min | Max depth: 35 meter | Average depth: 22.3 meter
Water temp: 5° | O² used: 90 litre | Dil used: 150 litre | Total RB divetime: 27h 04min

Went out on the Baltic sea for the second day, today we where going to dive the S/S Nicomedia, which is the biggest ship of the 4 sunk by the British submarine E19 in 1915. S/S Nicomedia LOA is 120 metres. It was a great dive, my MkVI worked flawlessly, and it was an impressive wreck to dive on. I will need to go back here, once my deco course is completed.  As you can see on my divelog above, we missed the wreck, following the anchor line down to the bottom at 35 meters. It was impressive to see the whole ship in front of you, looking up some 10-12 metres to the deck and railing. Went into some of the large cargo holdings. Great dive.

Dive #92

Location: S/S Director Reppenhagen, Baltic Sea, Sweden
Time down: 14:53 | Time up: 15:33 | Divetime: 40 min | Max depth: 38 meter | Average depth: 23.2 meter
Water temp: 5° | O² used: 102 litre | Dil used: 180 litre | Total RB divetime: 26h 22min

My first dive on what is called the U-boat massacre. In 1915, an british U-boat (E19) sank 4 merchant vessels in one day. They where an route to Germany with iron and other supplies. S/S Director Reppenhagen is one of these 4 ships. I did a video with my new Hero GoPro 2. I got a C1 alarm during the dive (low confident in oxygen cell). So I bailed out, stopped and thought about it. Went back to the loop, semi closed for a minute. Machine was working properly, could hear the O2 solenoid firering, pPO2 looked good. Alarm cleared in a minute. Continued the dive. It was a great dive, and my deepest Rebreather dive to date. Light Deco obligation on the MkVI, which cleared as we ascended.

Dive #91

Location: Ablahamn, Kullen, Sweden
Time down: 18:09 | Time up: 19:49 | Divetime: 100 min | Max depth: 20.9 meter | Average depth: 15.0 meter
Water temp: 8° | O² used: 165 litre | Dil used: 255 litre | Total RB divetime: 25h 42min

Goal of today was to do a 100 min dive with bailout exercise, and handling of twin stage tanks. The dive went smooth with an average depth of 15 meters. They say that training makes it perfect, and I need a lot of training handling two tanks on the side. I definitely need more practice. Being shallow when practising makes it more difficult, but if you can handle buoyancy and tank switches on 6 meters, you can do it just as easy at 21 meters. But it was cool doing a 100 minute dive.
