On Monday 7th September I flew to Istanbul, Turkey to complete my adjudication of the longest scuba dive in a controlled environment. I had seen the beginning of the attempt as in my previous blog, so now was the time to return to examine the evidence.
To recap, Cem Karabay went into the tank in the car park of the Beylikduzu Migros Shopping Mall in Istanbul on 30th August at 19.45. His attempt was streamed live on his website and as per the guidelines provided by Guinness World Records, he had a support team to aid his various neccesities such as changing oxygen tanks and any health/sanitary requirements. He was also required to be monitored by two witnesses at all times, who had to rotate every 4 hours, signing at the beginning and end of each shift. As controlled environment was a new category, Guinness World Records had stipulated that in order to set this new record Cem would need to at least equal the existing record for open fresh water of 120 hours, 1 minute and 9 seconds.
I had learned that Cem had surfaced prior to my arrival, but it was still necessary to verify his time underwater and the evidence as required by the guidelines. On arrival at the shopping mall the atmosphere was intense. There were around 12 press channels waiting for my verdict and the certificate presentation if the attempt was successful. I took my time to carefully examine the evidence and when I was satisfied with what I had seen, I announced my findings to the large audience and press. Cem Karabay had managed to remain underwater for 135 hours, 2 minutes and 19 seconds, setting a new Guinness World Record.
Below are some pictures of the event including a press cutting showing Cem's hands shortly after emerging from the tank!

Longest Scuba Dive - controlled environment
On Sunday 30th August I flew to Istanbul to adjudicate the start of Cem Karabay's attempt to set a new Guinness World Record for the longest time spent submerged underwater, in a controlled environment, using self contained underwater breathing apparatus (SCUBA). Cem (pronounced 'jem') is aiming to spend 10 days and 10 nights in a tank in the car park of a well known shopping centre, without rest breaks and without coming to the surface.
On arrival I immediately noticed how much preparation had gone into this attempt. Everything had been incredibly well organised and every member of Cem's support crew were trained divers. Leading the crew was Namik Ekin, ex Navy Seal, who had set up several fitness centres in Istanbul over the years and had trained all of the divers present. According to the guidelines, Cem is allowed a support crew to change his oxygen tanks etc, but is not permitted to come to the surface or have any link with the surface for the duration of the attempt.
A lot of people present including the press were curious how Cem would eat, sleep and use the toilet during his time underwater. I asked him beforehand and he answered that eating and drinking would not be a problem as you can't eat or drink and breath at the same time anyway. He explained that when he wants to sleep he has a full face mask, enabling him to breath normally in his sleep. Regarding using the toilet, he will have a special tank-like piece of equipment built into his diving suit which can be changed by the support crew during the attempt. Interestingly, among the various things in the tank with Cem, which includes a blow-up mattress and a glass table, there is an exercise bike. I was told that as he would be out of normal gravity conditions, he would need to exercise in order to prevent muscle wasting!
At 19.45 in front of an audience of around 10,000 people, Cem descended into the tank after doing many interviews with the national and international press. He seemed confident, joking around doing break-dance moves and signaling to the public who were now crowded around the tank.
After a couple of hours however, he started to shake uncontrollably and I watched divers in rotation frantically diving with hot water bottles in an attempt to warm him up. The water heaters had not arrived in time for the start of the attempt, so the crew were forced to improvise. A few hours later they finally managed to get it under control and as Cem prepared to sleep, I returned to my hotel.
The next morning I returned to the site and Namik showed me a painting done by a 7 year old girl the evening before of Cem in his tank. He translated her message written on the back saying, "Heroes always make it, because they are strong. According to my idea, you are a hero and you will make it".
The underwater video of this attempt is being streamed live on Cem's website, www.cemkarabay.com. Click the Union Jack flag to translate into English. Only viewable using Internet Explorer.
